HPMC for Wall Putty

Wall putty is also known as a plaster/skim coat. It is the material used for preparing and smoothing walls before painting.

 

WOTAIchem is your trusted HPMC manufacturer in China. We provide quality HPMC for wall putty that reduces water loss in mortar or cement formula.

 

WOTAIchem HPMC for wall putty works perfectly for both interior and exterior wall applications in dry mix mortar formulations. Our HPMC polymer provides thickening, water retention, and lubrication resulting in wall putty.

 

  • Extend the opening time.
  • Fast dispersion in cold water.
  • Provide high viscosity for wall putty.
  • High water retention. HPMC chemicals can maintain enough moisture in putty mortar.

China HPMC Manufacturer - WOTAIchem

Wall putty is made from fine white cement-based powder, that pastes on the walls before the painting job. It makes your wall surface even and smooth. Before painting, wall putty is a significant step to increase the endurance and hardness of your wall.

 

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 is applicable to the internal and external walls of the building. The 2nd layer of wall putty touches up to fix all the imperfections, and the 2nd layer makes a smooth and polished surface.

The 4 Biggest Advantages of HPMC in Wall Putty

HPMC-application
WOTAIchem Hydroxypropyl Methylcellulose

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.

FAQs

What is the most crucial additive in wall putty appltion?

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.

 

 

6 Easy Steps to Apply Your Wall Putty with HPMC?
What could be the reasons for wall putty coming off during the rainy season? How to solve this problem?

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.

Apply Wall Putty Tips & Tricks

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.
Is there a relationship between the powdering of putty powder and HPMC (Hydroxypropyl Methylcellulose)?

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.

What Is wall putty?

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.

What are wall putty advantages?
Wall putty is an important step before applying paints, it works like a primer to make your painting shine and strong and subsequently last longer. Putty is a fundamental element to even out, creating a smooth and flawless surface.
Wall putty materials are with high plasticity, and it’s similar to the texture of clay. A protective smooth layer base for paint application.
What's the difference between wall putty and POP?

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.

Which is a better option pop or wall putty?
Both building materials have pros and cons.
Wall putty has many plus points against pop. pop brings delicacy and sophistication to house design. Wall putty makes a smooth and flawless finish, most importantly, more durable.
POP is only applicable for internal wall and ceiling designs.
Why do bubbles occur in putty applications?

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.

What is the difference between waterproof putty and normal putty?

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.
