Things to note when using a Tjhoko – Yellow, Red or White colour to paint over a dark surface.
- Clean the surface properly by washing it off with Lacquer Thinners.
- Wait 20-40 minutes for the Lacquer thinners to dry.
- Depending on the surface you are painting you can either use a Paint Brush, Foam roller or Mohair roller.
( For large flat surfaces use a Mohair roller. For Kitchen cupboards a foam roller is better to use. ) paint a base coat in Stone Wash and allow to dry.
- Ensure that your applicator is clean a dry and that the base coat has dried properly before you start painting on top of your base coat with White, Yellow or Red Tjhoko Paint colours.
- Very important is to allow for each coat of paint to dry completely before applying the next coat.

How to paint:
Step 1 – Clean surface PROPERLY with Lacquer thinners (we use Powerfix Lacquer thinners). Wear gloves and work in a well-ventilated space.
Wait until the lacquer thinners is dry 20 – 40 minutes. I would then repeat the cleaning process again. (WE DON’T RECOMMEND TO PAINT ONTO A VARNISHED SURFACE IF THE SURFACE HAS BEEN VARNISHED WITHIN THE PAST 6 MONTHS. Varnish takes at least 6 months to cure. When painting onto an enamel surface – contact us at support@tjhokopaint.co.za to give the right advice.)
Step 2 – Start painting. We recommend painting at least two coats. Very important when painting is to always allow a coat of paint to dry properly before the next coat of paint is applied. Depending on the colour being used a third coat would be necessary for example painting a white paint onto a darker surface.
The equipment you use for painting also plays a role. A foam roller leaves a much thinner coat of paint than a paint brush. Therefore, more coats of paint would be required when working with a foam roller.
The paint does have a matt finish (Tjhoko Paint is a self-sealing, water-based, matt chalk paint) it does not need a sealant unless you have the piece of furniture outside or in a room like the kitchen or bathroom where there is lots of moisture. The Glaze makes the surface water and UV-Resistant. It also prevents stains and provides a more washable surface. We also recommend to seal tabletops and pedestal tops, kitchen, and bathroom wall tiles (painting in showers not recommended).
Step 3 – If you are applying the clear glaze, always allow the paint to dry for at least 4 hours before starting with the glaze application. In coastal areas or during winter months we recommend to only start glazing the next day (leave paint to cure overnight).
- Dilute the Clear Glaze with 30% water (30ml of water for every 100ml of Glaze) or 3 parts Clear Glaze and 1-part water. (we recommend cooled, boiled water as it is less contaminated)
- On darker Tjhoko colours we recommend 50/50 (1-part Tjhoko Clear Glaze and 1-part water. You can also use this ratio for a less sheen finish.)
- Dampen a clean, colourless cloth with water and squeeze to remove all excess moisture. A Microfibre cloth works best.
- Dip the cloth completely in the mixture to absorb the mix and then squeeze to remove excess moisture.
- Evenly wipe onto the painted surface. Work in a well-lit room to ensure that the entire surface is covered. If streakiness or lines occur – (it is caused by the fabric / cloth) just apply a second coat, half an hour later.
- Should you wish to change colour or add paint techniques over the clear glaze, you can do so once it it has cured for an hour or longer.

A rust product that you can use to treat rust is a product called Rust Converter.
In the areas that you have applied and used the rust converter you will also be washing the surface off ( this is all part of the instructions)
You would not need to then clean these washed areas with Lacquer thinners as the Rust Converter etches the surface and cleans it. Only the areas that you have not cleaned with the Rust Converter would require for you to clean with the Lacquer thinners.

- The Enamel surface needs to be older than 6 months.
- Test a small area to see if sanding would be needed in conjunction with the cleaning.
- Clean a small area with Lacquer thinners – wait 20 minutes and paint your first coat – allow to dry and then paint your second coat.
- Wait for 24 hrs and then test by scratching the surface.
- If the paint is removed by scratching we advise that you sand first and then clean with Lacquer thinners – this will make sure that the paint will grip onto the surface. Once you have painted x2 layers and waited 24 hrs – repeat the scratch test again. If the paint continues to be scratched off, a universal undercoat would then be need to be applied.
- It is not uncommon for many enamel surfaces to pose a problem when painting on top of them.
- Sand with 100grit sandpaper.
- Clean well with Lacquer thinners and then start painting.
- Larger surfaces need to be tested before painting starts. ( As above)

Yes, you can. It is important that the furniture is in a good condition. If it is water damaged or very rough, you need to sand it first so that the wood surface is even. The next step is to clean it very well with lacquer thinners. Wait 20-30 minutes for it to dry and then start painting. You will need 2-3 coats depending on the colour of the paint and also the colour of the surface that you are painting on. After your final coat, you must wait at least 4 hours. You can then apply glaze. Dilute it with 30% water and apply it with a damp cloth. Rub it evenly over the surface. Make sure your cloth is not too wet. Apply at least 3 coats of glaze and wait at least 30 minutes between every coat. Maintenance will still be necessary, if you see any damage, touch it up with paint and glaze. Wood will shrink or swell because of the fluctuations in temperature and therefor touch ups may be needed.

- Clean the surface well by wiping clean with a cloth dipped in Lacquer Thinners.
- Wait 20 minutes for the Thinners to dry.
- Use a dry, clean paintbrush for painting.
- Paint a base coat in one of the Tjhoko Paint colours like Sherif’s Stone and allow to dry.
- Sir the Metallic Paint well before and during use.
- Paint with clean, dry brush.
- Allow for each cost of paint to dry completely before applying the next coat.
- Coverage of metallic paints differ from normal Tjhoko colours due to the water-based metallic composition.
- Dry-brush technique also recommended.
See the whole article
• Always work with a clean, dry
paintbrush.
• Ensure that the surface being painted on is clean and
mould-free.
• Do not add water into the paint container.
• Ensure that the rim of the jar is cleaned after each
use and that the lid is properly sealed after each use.

The trick to stencilling is to use as little paint as possible, evenly distributed onto a stencil brush. Test by wiping the stencil brush on a piece of newspaper, if the stencil brush is wet you are using too much paint. Remove any excess paint onto a piece of newspaper. The dryer the brush the greater the success.
Secure the stencil using masking tape. The masking tape secures the stencil but also allows a larger area to work on.
Move the stencil brush in a circular movement when applying it to the stencil. Holding the stencil down with your free hand.

Remove any excess paint with a damp cloth or rag that you do not mind throwing away. Flush out the stain with warm running water, starting from the back of the clothing item. Create a solution of equal parts dish-washing liquid soap and warm water. Rub the solution into the stain with either your fingers or a different, clean rag to attempt to remove any remaining paint on the garment. Rinse the item, and repeat the process if necessary, to remove any remaining paint.
Wash the item as directed on the tag. Pour any detergent used in the wash directly on the stain prior to placing it in the wash for extra stain removing power. Inspect after the cycle ends. If the stain is not completely removed, repeat this step until the stain is removed. Do not dry the garment until the stain has been removed.
Bicarbonate of Soda can also be mixed with water into a paste and rubbed into the stain. Soak for a few days and hand wash regularly.

Yes, but because plastic is an oily surface, we would suggest that you:
Step 1: Lightly sand the entire object, just to create enough of a rough surface area for the paint to hold.
Step 2: Clean well with Lacquer Thinners and allow to dry for 20 minutes. (refer preparation with Lacquer thinners).
3) Start painting.
4) If the object or piece of furniture is going to be outside, we would finish with a clear glaze which will protect it against the outside elements. (refer Clear Glaze application)

Yes. Although we would rather recommend stencilling the tablecloth.
We suggest ironing the back more or less an hour or two after painting. Hand wash in cold water and ensure that you paint on natural fabric, not something with a shine.
We don’t recommend painting on synthetic fabrics.
See the whole article
Yes, you can. It is very important to remember is that paint will change the feel and texture of fabric. Also depending on the flexibility of the foam, hairline cracks might appear. The more flexible the foam, the more movement there will be. The amount of paint needed will depend on the absorbency of the foam and fabric. More or less 1 L per 2 squares are required on fabric, but it can differ.
Steps to follow:
Evenly spray the fabric with water. Don’t dilute the paint and evenly and thinly paint a first coat of paint. Wait for first coat to be hand dry (meaning if you touch the paint there is no paint coming off) then apply a second coat of paint. In some instances, even four coats can be required. The number of coats needed depends on absorbency of fabric and foam.
No sealing or glaze is needed once paintwork is complete.
We ALWAYS suggest TO TEST FIRST to see if you like the effect and different texture caused by paint on a fabric and only then continue.

Yes, you can. Just remember to clean with Lacquer Thinners (wear gloves and mask) to remove grease and dirt. Allow the surface to dry and then paint.

Yes, you can use Tjhoko Paint on genuine leather. You just need to make sure that the leather is cleaned properly and is grease free before you start painting.
Clean well using Lacquer Thinners to remove all the oil, allow to dry for 20-30 minutes and then start painting. No need to seal with Clear Glaze.

Solvent paints take 14 days to cure, varnish and linseed oil take6 months. So, when painting on an oil based surface the best advise is to rather first prime it with Universal Undercoat. Allow 24 hours for Universal Undercoat to dry and then apply Tjhoko Paint in the preferred colour.
On varnished or oil treated surfaces (not furniture polish) allow 6 months for varnish or oil to cure and only then paint.
Furniture oil needs to be removed properly using Lacquer Thinners. Wear gloves and a mask
See the whole article
You would need to make sure that the wall you are going to paint on has not been painted with an oil-based paint, this would inhibit the Tjhoko Paint from sticking to it.
If this is the case, you would need to apply a Universal Undercoat or remove the oil based under layer.
All peeling paint would need to be removed. Cracks need to be filled and thereafter cleaned with Lacquer Thinners.
You will then be ready to paint.

If the paint is not gripping it might be because of a few spots of cleaning that may have been missed or in some instances when the varnish hasn’t cured.
If the surface is cleaned properly with Lacquer thinners this should not be a problem.
Recently varnished surfaces. Varnish needs more or less a 6-months curing time before you can paint onto a varnished surface.
An oil treated surface (linseed oil and other oil products) also needs more or less a 6-months curing time.
See the whole article
The cleaning process is very important and all oil needs to be removed before starting to paint. Another important factor is a clean brush and equipment. One of the reasons why this is happening is due to oil on the surface that prevents the paint from gripping.
See the whole article
- Recently varnished surfaces. Varnish needs more or less a 6-months curing time before you can paint onto a varnished surface.
- An oil treated surface (linseed oil and other oil products) also needs more or less a 6-months curing time.
- If a surface was waxed within 6 months you need to sand first. The paint will not grip onto wax as the wax itself disintegrates. The surface needs to be wiped down WELL with Lacquer thinners.
- Wait 20 minutes and then start painting.
See the whole article
Yes, you can! There is no need to sand the piece of furniture, you just need to make sure it has been cleaned. We always suggest a wipe down thoroughly with Lacquer thinners. Refer to the cleaning guide.
We do not recommend painting on a recently varnished surface or a surface that has recently been oil treated (like raw linseed oil treated surfaces). Surfaces like the above needs a 6-month curing time before paint work can be attempted.
Waxed surfaces and plastic surfaces need to be sanded first with 100 grid sandpaper and then thoroughly cleaned with Lacquer Thinners.
Surfaces like previously varnished surfaces (varnish older than 6 months), laminated surfaces, melamine surfaces, wall tiles, leather and faux leather need to be wiped clean properly using Lacquer Thinners. Use a mask and gloves and clean these surfaces well. Wait 20 minutes and then start painting. If it is a very oily surface cleaning will need to be repeated until all oily residues are removed.
Once you have finished painting you can decide if you would like a matt or sheen finish. We recommend using the Clear Glaze in areas such as bathrooms, kitchens and outdoors. Tabletops and pedestal tops need to be glazed with the Clear Glaze.
The paint naturally gives a matt finish, but by applying our Clear Glaze as per the instructions (refer to Clear Glaze application) this will give you a subtle satin finish. Should you want a higher gloss finish, more coats of Glaze can be applied, wait 30 minutes in between coats.
Sometimes you might find yourself painting a piece of furniture that has been polished and cleaned for years, this may lead to oil seeping through when it is painted, even after the cleaning process.
In this instance the following is recommend:
- After your second coat of paint, wait at least 4 hours.
- Put on gloves. (The Glaze is nontoxic it is a water based pure acrylic sealant and a latex film will be left on your hand if not wearing gloves. Your hands can be washed with warm soapy waters should you prefer not to wear gloves. Just a useful tip!
- Dip a damp, clean, colourless cloth in the Clear Glaze (do not dilute the Glaze). It works well if you pour the Glaze into an ice cream tub and work from there. Squeeze out excess moisture and evenly wipe the surface with a good, even coat of Clear Glaze.
- Leave for 12 hours and then repaint onto the Glaze.
The Glaze acts as a barrier between the bleeding and the paint coat.

Yes, absolutely you can paint your dining table.
A mohair roller works well to paint a large flat surface.
Below some steps
- Make sure that the table is clean before you start painting. Clean properly with Lacquer thinners. Refer to the cleaning guide.
- Wait 20 minutes for Lacquer Thinners to dry.
Once the surface is clean and dry you can apply your colour. We would suggest you use a Mohair roller for the application of the paint to make it more even, below is a link to our video gallery. Watch the video below to see how to use this roller.
More than one coat will be necessary. Always wait in between coats for paint to dry.
Once you have finished painting allow to dry for 4 hours and then apply our clear glaze to seal the tabletop and if the table is standing outside seal the legs too.
Always allow the paint to dry for at least 4 hours before starting with the Glaze application. In coastal areas or during winter months we recommend to only start glazing the next day (leave paint to cure overnight)
- Dilute the Clear Glaze with 30% water (30ml of water for every 100ml of Glaze) or 3 parts Clear Glaze and 1-part water.
- Dampen a clean, colourless cloth with water and squeeze to remove all excess moisture.
- Dip the cloth completely in the mixture to absorb the mix and then squeeze to remove excess moisture.
- Evenly wipe onto the painted surface. Work in a well-lit room to ensure that the entire surface is covered. If streakiness or lines occurs (it is caused by the fabric/cloth) just wipe a second coat, half an hour later.

Yes, you can paint on bathroom wall tiles.
What you need:
- Lacquer Thinners
- 2 pieces Mutton cloth cut to the size of a kitchen towel
- 110mm or 160mm foam roller and handle or paintbrush depending on your preference.
- Paint Tray
- Tjhoko Paint in a colour of your choice
- Tjhoko’s Clear Glaze
Method:
1. Clean the surface well with Lacquer Thinners.
2. Important is to use gloves and a mask.
3. Wait 20 minutes for Thinners to evaporate
4. Pour some Tjhoko Paint in a paint tray
5. Use the foam roller and wet it well in the paint ensuring that it is covered in paint all around.
6. Start by evenly rolling the paint onto the surface. Don’t worry if air bubbles appear. These will disappear as the paint dries. Be careful not to over work the foam roller: Don’t roll too much – this is when a rough surface is created once the paint has dried.
7. Once the first coat is evenly applied, allow the paint to dry (more or less 30 minutes) before the next coat is applied.
8. Once the paintwork has been completed wait at least 4 hours before the glazing process starts.
9. Apply the clear Glaze:
Clear Glaze is a pure acrylic product, which proves to be an excellent sealant.
It is water-based.
- Clear Glaze: As the name describes, it is colourless. Dilute 100ml Glaze at a time with 30ml of water in a different container
- It helps to wear gloves.
- Use a clean, colourless piece of cloth (mutton cloth or T-shirt material) and dampen the cloth with water. Squeeze and remove any excess water.
- Dip the damp cloth in the Glaze mixture and once again squeeze to remove excess Glaze mixture.
- Wipe very evenly onto the painted surface.
- Work in a well-lit area to ensure that the entire surface is covered and that no blank spaces are left un-glazed.
- One glaze coat is enough. When a higher satin finished is required or to remove any streakiness, a second coat of Glaze can be applied.
- When the cloth becomes dry or sticky, rinse in water and repeat the process.
Stand back and enjoy your creation!

Yes, of course you can paint kitchen cupboards.
What you need:
- Lacquer Thinners
- 2 pieces Mutton cloth cut to the size of a kitchen towel
- 110mm or 160mm foam roller and handle or paintbrush depending on your preference.
- Instead of using a foam roller a Mohair roller can be used on large flat surfaces or cupboard doors
- Paint Tray
- Tjhoko Paint in a colour of your choice
- Tjhoko’s Clear Glaze
Method:
- Clean the surface well with Lacquer Thinners.
- It is important to use gloves and a mask.
- Wait 20 minutes for Thinners to evaporate

We don’t recommend using Tjhoko paint on floors. Floors are very specific and tricky, they are generally very high traffic areas and need a cover that has been specifically designed to last through the repetitive wear and tear.
See the whole article
The number of coats that will need to be applied, will depend on the absorbency of the fabric and the foam. Each layer needs to be hand dry (dry to the touch) before the next coat is painted on.
It is the flexibility of the foam inside the coach that determines whether the fabric will crack or not.
The more flexible the foam the higher propensity there may be for the fabric to crack, but sometimes this does not happen.

Below are two links that will assist you with the application of the paint on fabric.
Ensure that you are working on a natural fabric item, like suede or cotton, and not something that is synthetic. Always keep in mind that paint will change the texture of the fabric. We always recommend painting a small section and test first.
Tips: Never dilute the paint with water.
There is no need to apply a sealant or Clear Glaze afterwards.
Care instructions: Hand wash in cold water.
- When painting on upholstery, first moisten the fabric with some water. (A spray bottle filled with water works well.) This will help to use less paint and add some elasticity to your first coat of paint.
- Then apply the 1st coat of paint on top of the moist fabric, wait for the paint to be hand dry.
Hand dry means that when you touch it, no paint should come off.
- Next apply a 2nd coat of paint and depending on the fabric you are painting onto maybe it will need a 3rd or 4th coat (No sealant is required or needed)
The 1st link shows you the application onto an ottoman. The 2nd link shows the application of the paint onto a table runner. Both fabric applications are towards the end of the content clips. On a loose item such as a runner or tablecloth, iron on the back more or less 2 hours after the painting has been completed.

We haven’t actively used the paint to dye with,
but we do have a stockist that does it on natural fabrics so it can be done. Best is to always do a test run first and rather use natural fabrics than synthetic fabrics.
This is how she does it:
- In a basin or bowl, pour lukewarm water and add the paint colour of your choice, as much as what is needed to get the desired colour.
- The fabric is placed in the water and stirred every 1/2hr over a 2-6 hr period until the fabric is dyed evenly.
- Remove from water and allow to dry.
- Iron the fabric
- Care Instructions: hand wash in cold water.
- Fabric should be a natural woven texture and not synthetic.
We do suggest you try a small piece first.

Sometimes if a piece of furniture has been oiled so much over the years that streaking and discoloration of the paint may appear even after you have cleaned with Lacquer Thinners and prepared the piece of furniture for painting. This is called bleeding and occurs due to the amount of oil that has been absorbed into the wood. In this event we recommend doing the following:
- After your second coat of paint, wait at least 4 hours.
- Put on gloves. The Glaze is non-toxic and is a water based pure acrylic sealant that will leave a latex film on your hands if you are not wearing gloves. It can however be cleaned from your hands with soap and warm water should you prefer not to wear gloves- Just a useful tip!
- Dip a damp, clean, colourless cloth in the Clear Glaze (do not dilute the Glaze). It works well if you pour the Glaze into an ice cream tub and work from there. Squeeze out excess moisture and evenly wipe the surface with a good, even coat of Clear Glaze.
