HPMC for Wall Putty
Wall putty, AKA skim coat. It’s a material used for preparing and smoothing walls before painting. HPMC hydroxypropyl methyl cellulose is an essential additive in wall putty mixture.
HPMC for wall putty works perfectly for both indoor and outdoor walls. It’s a drymix material where you mix all the ingredients first and then add water to it at construction site.
At WOTAIchem, our HPMC provides multiple benefits in wall putty application.
- High water retention and excellent workability for putty mortar.
- Extend the opening time, allowing you more time to apply.
- Fast dispersion in cold water, reducing your stirring time.

4 Key Benefits of HPMC in Wall Putty
Excellent Water Retention
HPMC is a reliable and consistent ingredient for creating a uniform putty solution ready for application. It is created to ensure enough moisture remains in the substrate and achieve full hydration.
Increase Operationality
HPMC is a highly efficient ingredient that dissolves rapidly in cold water. It increases the solution’s viscosity. As it has a hydrophilic nature, HPMC can also extend working time. Consequently, waiting times are shortened, and productivity is increased
Enhance Workability
HPMC offers superior thickening, dispersion, and film-forming capabilities. It reduces moisture evaporation during wall putty application. And it greatly improves work efficiency. Thus, HPMC is an ideal selection for wall putty applications.
Sag Resistance
HPMC for wall putty excels in preventing drips and sags. It keeps wall putty firmly in place on vertical surfaces, ensuring a smooth finish for your wall putty projects. Whether you’re a professional or a DIY enthusiast, HPMC simplifies your work.

Major Application Scenarios for HPMC in Wall Putty
FAQs
HPMC is an important ingredient in wall putty to prepare walls for painting or wallpapering. WOTAI HPMC is a non-ionic cellulose ether derived from natural polymer materials. It has many beneficial properties in wall putty applications.
In addition to its benefits for wall putty, WOTAIchem HPMC is also used in many other applications in construction. It is used as a binder in cement and concrete. A thickening agent in tile adhesives and grouts. And a water retention agent in gypsum products.
Wall putty coming off is a common issue during the rainy season. The possible causes are:
1.Insufficient Cement Addition:
Not using enough cement in the mixture can weaken the putty, making it more susceptible to damage and peeling.
2.Adding PVA:
Polyvinyl acetate (PVA) is not water-resistant. Using PVA in the putty mix can result in the putty absorbing moisture and coming off.
3.Excess Sodium Gluconate:
Adding too much sodium gluconate can reduce the strength of the cement, leading to a less durable putty that is more likely to peel off.
Recommendations
For exterior walls, ensure that the amount of white cement in the water-resistant putty is at least 30%.
1.Add 5-10% lime (quicklime) to enhance the water-resistant effect.
2.Keep the amount of sodium gluconate to 0.15% of the cement weight to maintain the strength of the putty.
Many people think that as long as you choose nice paints, you will achieve a beautiful wall finish, but in fact, you need more than that. The best paints are necessary for flawless and shining walls.
However, you can’t do that without wall putty. Your wall painting depends on wall putty design in the first place. it’s the fundamental thing. Wall putty makes your painting strong and long-lasting. You may consider to take the following steps:
- Clean the walls. Use sandpaper to polish the surface.
- Mix putty with water in the right ratio, refer to the user guideline.
- Apply the first layer of putty. leave it for 6-8 hours to dry out.
- Avoid overcoating. The maximum thickness should be 1.5mm.
- If the first layer isn’t good enough, apply a second layer.
Wall putty powdering issue is mainly related to the quality of calcium hydrate (lime). It has little to do with HPMC. The powdering is influenced by the low calcium content and improper ratios of CaO and Ca(OH)2 in the calcium hydrate.
If there is any connection to HPMC, it would be related to its water retention properties. Poor water retention of HPMC could contribute to powdering. However, HPMC itself does not participate in any reaction.
Wall putty is essentially made for filling in gaps, cracks, and even holes on the wall surfaces, and leaving a plain and even surface before applying paint. Wall putty applies to the internal and external walls of the building.
Wall putty. The walls need to be cleaned first with a metal brush, and sandpaper. Putty is used to smoothen the walls, and remove uneven surfaces. POP stands for plaster of pairs. Constructors apply a thick layer of pop straight away on the brick walls. POP is not applicable to outdoor walls because it doesn’t last long.
HPMC serves 3 functions in putty powder: thickening, water retention, and facilitating construction. It does not participate in any chemical reactions.
Bubbles may occur due to excessive water content or applying a new layer of putty before the underlying layer has dried. We recommend to add antifoaming agent in your putty formula.
Waterproof putty is specifically formulated to resist moisture and prevent water penetration. Making it suitable for damp or wet areas. RDP and HPMC are recommended to add to the formulation. Normal putty lacks this water-resistant feature and is used in dry environments.
