How to Make Your Own Wall Putty with White Cement and Talcum Powder

Wall putty is a material that is used to fill up the fine pores and cracks in the walls and ceilings, and to provide a smooth and even surface for painting. Wall putty can also protect the walls from moisture, efflorescence, and flaking. Wall putty is usually made of white cement, fillers, polymers, and additives. However, you can also make your own wall putty with some simple ingredients that you may already have at home.

In this article, we will show you how to make your own wall putty with white cement and talcum powder, based on a guide formulation from Hoffmann Mineral[^1^] and a product description from Jay Chemical[^2^]. You will need the following materials:

White cement (240-300 grams)

Talcum powder (550-700 grams)

Water (180-210 ml)

A mixing bowl

A spatula or a blade

An electric mixer (optional)

Follow these steps to make your own wall putty:

Put the white cement and the talcum powder in the mixing bowl and mix them well.

Add water slowly and gradually while stirring the mixture until you get a smooth and consistent paste. You can use an electric mixer to speed up the process.

Use the wall putty within 2-3 hours of preparation. If the paste becomes too thick or dry, add some more water and mix well.

Apply the first coat of wall putty on the wall with a spatula or a blade, starting from the bottom and moving upwards. Make sure the surface is clean, damp, and moderately rough.

Let the first coat dry for 6-8 hours in winter or 4-6 hours in summer.

Apply the second coat of wall putty horizontally to even out the application marks of the first coat. The total thickness of both coats should not exceed 1.5 mm.

Let the second coat dry for 3 days and then use a fine emery paper (not less than 500 number) to remove any imperfections.

Your wall is now ready for painting.

This homemade wall putty has many benefits, such as:

It is easy to make and use.

It is water-resistant and durable.

It reduces paint consumption and enhances paint adhesion.

It gives a smooth and white finish to your walls.

If you want to learn more about wall putty formulation, you can also check out this patent from Google[^3^] that describes a putty powder formula for exterior wall that uses calcium carbonate, cellulose ether, redispersible latex powder, hydroxypropyl methylcellulose, polyvinyl alcohol, sodium hexametaphosphate, sodium carboxymethyl cellulose, defoamer, fungicide, and water.

Wall putty is not only useful for improving the appearance and durability of your walls, but also for enhancing their thermal and acoustic insulation. Wall putty can help reduce heat loss and noise transmission through the walls, making your home more comfortable and energy-efficient. Wall putty can also prevent the growth of mold and mildew on the walls, which can cause health problems and damage the paint.

However, wall putty is not a substitute for proper plastering and curing of the walls. Wall putty can only cover up minor defects and irregularities in the wall surface, but it cannot fix structural issues or cracks that are deeper than 3 mm. If your walls have major damages or cracks, you should consult a professional before applying wall putty or paint.

Wall putty is also not suitable for all types of surfaces and paints. Wall putty is best applied on cement-based surfaces, such as concrete, plaster, or aerated light-weight blocks. Wall putty may not adhere well to other surfaces, such as wood, metal, or plastic. Wall putty is also compatible with most types of paints, such as acrylic, emulsion, or distemper. However, wall putty may not work well with oil-based or enamel paints. You should always check the compatibility of wall putty and paint before using them on your walls. aa16f39245
