The answer you’re looking for is the Trimurti Products’ Waterproof Wall Putty.

This specialized formula not only guarantees a smooth, crack-free finish but also provides lasting fortification against moisture, cracking, and peeling. By using it, you ensure your paint endures longer and maintains a flawless appearance for years.

This blog will take you through the benefits and applications of exterior wall putty and choosing the best products for your walls.

Why Skipping Wall Putty For Your Exterior Walls is Not An Option?

Skipping crucial protection for your exterior walls, given the massive environmental exposure, is a risk. Given the harsh environmental factors exterior walls face, applying waterproof wall putty is essential and should not be avoided. This step safeguards your investment and provides the necessary foundation for achieving a clean, smooth paint finish. Using this wall putty ensures that any remaining imperfections are filled, guaranteeing the paint job is completed to the highest standard.

Another thing that makes using the wall putty non-negotiable is that it lets you avoid peeling off, mold, or cracks in the future. It’s important for durable, clean walls. Its water-resistant nature makes a solid foundation for plaster and walls, guarding them against water damage.

What Factors Affect the Durability of Exterior Walls and How Wall Putty Can Help?

Everyone likes the newly painted exterior walls of their home, but with time, these walls often lose their shine and strength. It’s not just the simple passage of time but environmental factors as well. From harsh UV rays to everyday temperature fluctuations, your walls go through a lot over the years. This is where a high-quality exterior wall putty application becomes your best bet.

Given below are some of the factors that affect your external walls and how wall putty can help tackle these issues:

  • Ultraviolet (UV) Rays

The harsh sun doesn’t just fade your clothes, but it also breaks down the chemical bonds in your paint and the underlying plaster. This leads to chalking and fading. The best exterior wall putty acts as a robust base layer, offering UV resistance that shields the plaster.

  • Temperature Changes

The constantly changing temperature due to the weather changes can really take a toll on your walls. They cause minor cracks in your wall surface, which then eventually become bigger over time. Using exterior wall puttyyou ensure that your walls are protected as they absorb these fluctuations, maintaining a seamless finish.

  • Moisture & Rain

Water is the natural nemesis of your exterior walls. It seeps deep into your wall cracks, causing dampness, mildew, and mold growth. This eventually leads the paint to bubble and peel. Using Trimurti Products’ specially formulated Waterproof Wall Putty, you create a waterproof barrier, blocking any moisture from entering. 

  • Pollutants

If you’re someone who lives in a city or near a busy road, your walls are constantly subjected to pollutants and dust particles. They simply dull your paint finish and cause the color to fade over time. A wall putty allows you to create a dense and non-porous surface that makes it easier for your walls to be cleansed or resist damage.

Essential Tips for Exterior Wall Putty Application

Yes, the right wall putty matters, but so does the exterior wall putty application. You have to make sure not to mess up the application. 

Follow these steps to ensure a smooth application:

  1. Preparing the Surface

Before anything else, make sure to get rid of all the loose material, dust, and dirt from the wall using sandpaper. Make sure your walls are clean of any oil or grease.

  1. Mixing the Putty

Now add the Trimurti Products’ Waterproof Wall Putty with 36-38% clean water to make a paste. You can leave the paste for 5 minutes after mixing to get the best results.

  1. Dampen the Surface

Before applying the wall putty, thoroughly pre-wet the entire surface using a brush or a hose pipe spray. This is a crucial preparatory step.

  1. Apply the First Coat

Apply the initial coat in a thin, uniform layer over the entire surface. Let this coat dry for several hours before moving on to the subsequent step.

  1. Sanding the First Coat

Once the initial coat is dry, the surface should be smoothed gently. Use a wet sponge or a putty blade to eliminate any loose particles, which will ensure a stronger bond.

  1. Apply the Second Coat

Apply a second, slightly thicker coat to ensure a complete and perfect finish. This final layer must be allowed to dry completely.

  1. Final Finish

After the second coat is completely dry, take fine sandpaper and gently sand the entire surface. This is done to eliminate any lingering roughness.
