Hydroxypropyl Methylcellulose (HPMC) For Wall Putty

Wall putty is a white cement-based powder made of polymer and other minerals that make the wall look smoother. It is primarily used to fill in cracks and holes in walls and prepare an even wall surface before applying paint. Using wall putty helps to provide better protection against stains, mould & cracks for your walls.

Wall putty is a versatile material that can be used on any wall, from precast walls to concrete and even rendered walls, providing the best paint and wall finish. Also referred to as paint putty, wall putt is usually applied before you paint the walls, as this helps better cover up cracks and holes that may otherwise obstruct the smooth application of wall paints. Depending on the surface, it may take 1-2 coats of painting putty coupled with sanding to make the surface ready for new paint.

The Role Of HPMC In Wall Putty:

● Good water retention will make sure all the additives reach the best performance in the product formulation.

● Good workability to increase the efficiency.

●HPMC/MHPC could provide a good filming property on the surface of the wall putty, could reduce the water absorption of the base wall. Reduce the risk of cracking.

● Good say-resistance property by providing a good viscosity of the wet mortar.

SLEO is a leading manufacturer of specialty chemicals, with a focus on producing Hydroxypropyl methylcellulose (HPMC), Methyl Hydroxyethyl Cellulose (MHEC), and redispersible polymer powder (RDP).

Advantages:

Improved Workability: HPMC enhances the workability of wall putty, making it easier to apply and spread smoothly on surfaces.

Water Retention: It provides excellent water retention, ensuring that the putty does not dry out too quickly, which allows for better curing and reduced cracking.

Adhesion: HPMC improves the adhesion of the putty to various surfaces, including concrete, plaster, and gypsum, resulting in a more durable finish.

Consistency and Stability: It helps in achieving a uniform consistency, preventing sagging and ensuring a stable mixture during application.

Resistance to Shrinkage and Cracking: The inclusion of HPMC reduces the risk of shrinkage and cracking as the putty dries, leading to a smoother and more uniform surface.

Note:

Addition ratio: Make sure to add HPMC to the putty in the ratio recommended by the manufacturer. Excessive addition may change the fluidity and drying time of the putty and affect the construction performance.

Uniform mixing: To ensure that HPMC is evenly distributed in the putty, mechanical mixing equipment should be used for sufficient mixing. Manual mixing may not achieve the desired uniformity.

Storage conditions: HPMC should be stored in a cool and dry place, avoiding moisture and high temperature to prevent agglomeration or failure.

Construction environment: Environmental conditions such as temperature and humidity should be considered during construction to ensure the best performance of the putty. Extreme temperature and humidity may affect the drying time and final quality of the putty.

Construction method: Use appropriate tools and techniques for construction, and ensure that the putty is evenly applied and of moderate thickness to avoid cracking or falling off.
