Product Information

Extended Coverage, Strength and Durability

A coat of JK PRIMAXX provides several benefits including: concealment of stains and reduction of blisters, extension of paint durability etc. Further more, applying this product before painting will provide extended coverage and a smoother finish.

Improved Paint Adhesion:

JK PRIMAXX has a distinct property of absorbing less paint when applied over new surfaces. It performs the dual functions of adhesion to the surface and also ensures that any successive layers of paint adhere to the surface more efficiently.

Effecting Hiding of Seams and Joints:

Due to its high cement content, the product has a very firm and inseparable grip over the wall. Being a Cement-Cement joinery, the joint is more natural and hence, any chances of cracks appearing due to physical forces of temperature i.e. heat and cold effect are eliminated.

Reduction in Construction Time and Cost:

The traditional primers increase/prolong construction time since they can be applied only when the plaster layer has completely dried out. Whereas. 1K PRIMAXX can be applied almost simultaneously while plastering work is going on. This reduces the total construction time and results in big savings in the overall project cost.


When using JK PRIMAXX in the wall finishing process, you get a dry polymerized material and water may be added on site. However, in the case of wet acrylic primers, you end up paying 50% just for the cost of water. By using JK PRIMAXX you end up saving 50% of your cost without compromising on quality.

Method of Application

Surface Preparation

Ensure that surface is completely free from all dirt, oil, grease or any other foreign matter. In case of old painted and unpainted surfaces, please remove thoroughly, loosely held plaster, powder by residue, any previous growth of fungus, algae or moss by vigorous wire brushing and cleaning with water. Prior to application, any cracks, voids & minor damages should be repaired.

Prior to applying paste, the surface should be pre-wetted properly to get better workability, binding property and coverage. This is one of the most important steps for achieving best results.


JK PRIMAXX is a product that needs careful mixing with water. Make a thick paste of the product by adding 50% water. Knead it by hand for 1 minute. Add balance quantity of water to the mix and a free flowing creamy solution is ready for placing on the wall by Spray/brush or roller application. Mixing could be done manually or by mechanical stirrer. Normally 1:1 mixing delivers a perfect solution. However, in extremely hot weather, water content can be raised even upto 1:1.3 to compensate the water loss due to high temperature and to kill the heat absorbed in the wall.

It is always good to leave the solution for the initial 10 minutes enabling it to mature. Always shake well before use and ensure that no settled materials are seen at the bottom of the bucket at the time of application. Make sure to use prepared mix within 3 to 4 hrs after preparation of paste.

Surface Application
  1. The thoroughly mixed paste should be applies by paint brush, roller or spray gun on the surface.
  2. If applied by a roller or brush, the direction of the movement should only be horizontal. This helps in getting a better finish, free of any brush marks.
  3. Apply 1-2 coats, leaving a minimum of 2-3 hours between different coats.
  • The approximate covering capacity of JK PRIMAXX is more than 100Sq. ft per coat.
  • The coverage depends upon various factors like Climatic condition and Temperature/Surface situation/preparation and porosity of the surface.

Surfaces Where it can be Applied

It can be used on all types of interior and exterior cement plasters, exterior ceilings, asbestos sheets, concrete and existing painted and unpainted surfaces.
