J.K. Wall Putty
For silky Interior/Exterior finish of your Dream House
Owing to its constant R&D efforts and technology updations, J.K. White Cement launched a value added product in 2002.
J.K. Wall Putty is a white cement based fine powder which provides an ideal base for concrete / cement plastered walls and ceilings. It gives you the most beautiful walls, is damp resistant and provides a smooth finish for further application of all kinds of paints. Its water repelling properties prevents flaking of your expensive paints.
J.K. Wall Putty is much better than ordinary putty as it becomes an integral part of the plaster due to its White Cement constitution. This gives better compatibility, adhesive-strength and a long-life to J.K. Wall Putty.
How to Apply
Preparation of J.K. Wall Putty paste
- Take required quantity of J.K. Wall Putty in a pan. 35-40% water by volume is required to prepare paste of good consistency.
- Mix half of required water quantity into it. Knead/Mix the Putty & wait for few minutes.
- Mix remaining quantity of water to get desired consistency.
- Mix vigorously for 5-10 minutes for making a lump-free and uniform paste.
- Mix the product in such quantities that it should be used within 2 hours of preparation.
- Mixing may be done manually or by using a suitable electric mixer.
Application of J.K. Wall Putty
- Ensure that surface is totally clean
- Ensure that surface plastered or made with cementitious material.
- The surface should be moderately rough and in just-wet condition.
- Apply 1st coat of J.K. Wall Putty (1.5 mm thickness) using a blade / spatula on the wall with a "bottom to up" configuration
- Apply 2nd coat of J.K. Wall Putty (1.0 mm thickness) preferably after 4 hours in summers and after 12 hours in winters. Second coat shall be applied "horizontally" to even out application marks of 1st coat, if any.
- Remove putty paste again for 1 minute, if it is left undisturbed for 30 minutes.
- Allow complete drying for 3 days and then use a fine emery paper to remove application marks, if any.

What is J.K. Wall Putty ?
J.K. Wall Putty is a White Cement based fine powder which provides an ideal finishing for concrete / cement plastered walls and ceilings. It provides an ideal base for painting and damp resistant smooth finish for further application of all kinds of paints. (It is very important to understand that damp resistance means resistance to water in humid air and not physical water contact / leakages).
What is the covering capacity of J.K. Wall Putty?
Maximum thickness of 1st coat (layer) 1.5 mm and maximum thickness of 2nd coat (layer) 1.0 mm. Approx achievable coverage is 35 sqft./mm/kg of J.K. Wall Putty. However, actual coverage achieved depends on the base surface condition and finished thickness.
Why is primer not required before painting when J.K. Wall Putty is applied on the wall ?
Since J.K. Wall Putty is made with very fine white cement and it fills all the pin holes and pores of plaster resulting in surface that has very less tendency of absorption, therefore, primer is not recommended after application of J.K. Wall Putty.
After how many days of application of J.K. wall putty, can paint be applied on the wall ?
Painting can be done after 3 or more days after application of J.K. Wall Putty but it should be ensured that J.K. wall putty is completely dry before applying paint.
How should the surface be prepared for J.K. wall putty application if the wall is showing signs of efflorescence / salt deposition?
If due to salty water or salt in sand / bricks, problem of efflorescence is observed then plastered surface should be treated with mild acid like citric acid before application of J.K. Wall Putty. Otherwise, wall putty will not stick to the wall and problem of flaking may arise. After 30 minutes of treating the surface with mild acid, surface should be washed thoroughly so that no acid remains on the wall. After drying properly, J.K. wall putty can be applied as normal. This treatment should be done under proper supervision.
What is reason of poor adhesion and flaking of J.K. wall putty near skirting?
During grinding of floor and skirting, slurry is produced. It sticks to the wall and becomes hard if not cleaned properly with wire brush before application of J.K. wall putty. The putty applied on surfaces will not give good result. Therefore, before applying J.K. wall putty near skirting it should be cleaned properly (with wire brush) and washed thoroughly to avoid flaking and poor adhesion, so that slurry deposited on the wall during grinding is removed totally. After drying the wall, putty can be applied as normal.
What is the reason of Peeling (Bubbles on wall) from base surface?
There are many reasons for (bubble) peel off. To obtain extra smooth and zero undulation finish, applicators exceeds the specified limit of thickness of J.K. wall putty film and also because when second coat is applied over freshly (poorly set) applied first coat of J.K. wall putty. The other reason could be that wall may have been painted earlier with cement paint or other paint which is water repellent. This results in reduced adhesion to wall and consequent spalling.
What is the pot life of the J.K. wall putty?
The pot life of J.K. Wall putty is 2 - 2.5 hours.
How much water is required for making paste of J.K.Wall Putty?
For making J.K. Wall putty mix approximately 33 to 38 percent of water is required by volume.
For how long J.K. Wall Putty mix can be used after mixing of water ?
Product should be mixed in such quantities that it can be used within 2 hours of its preparation. Mixing could be done by electric mixer rather than manual mixing.
What precautions should be taken during application of J.K. wall putty?
Ensure that surface is plastered or made with cementitious material. Ensure that surface is totally clean. Ensure that surface is moderately rough (Neither too-rough nor too-smooth). Ensure that surface is just wet. Over-wetting resulting in accumulation of water on surface should be avoided.
What is the time gap between first and second coat of J.K. wall putty.?
Apply second coat preferably after 4 hours in hot season & after 12 hours in cold season. Ensure that second coat is applied until first coat is fully set.
Should we add water into putty or putty into water ?
Always add water to J.K. wall putty while making paste. Adding putty in water may lead to formation of small nodules which will reduce the performance of the putty.
Is curing required after applications of J.K. Wall Putty ?
Curing is not required after applications of J.K. Wall Putty, However, after application, just sprinkling of water over applied surface for 2 days will enhance the hydration of cement particles which will give better results.
What is J.K. Coarse Wall Putty and what are the applications ?
J.K. Coarse Wall Putty is a White Cement based putty for plastered walls and ceilings. J.K. Coarse putty is a coarse powder specially formulated to be used as base coat to cover up undulation and uneven surfaces of cement plastered walls and concrete surfaces for exteriors and interiors. It can also be used directly over Brick work, Hollow Blocks, Precast Wall, Over Concrete and Ceilings.
