From Putty Peeling to Mortar Cracking: 6 Solutions with HPMC in Construction Projects

In the construction industry, putty peeling and mortar cracking are common issues that affect aesthetics and pose potential safety risks. HPMC, as an efficient construction chemical additive, provides reliable solutions to these challenges. 

Solution 1: Enhancing Putty Adhesion to Prevent Peeling

Putty peeling often results from insufficient bonding with the wall surface, leading to coating detachment. HPMC improves the adhesive strength of putty, ensuring it adheres firmly to walls and reduces the risk of peeling. With HPMC, putty application becomes smoother, resulting in a more uniform coating and extended wall lifespan, making it ideal for interior and exterior wall decoration.
Application: Residential renovations, commercial building wall coatings.

Solution 2: Improving Mortar Water Retention to Reduce Cracking

Mortar cracking is often caused by rapid water loss, which creates internal stress during hardening. HPMC’s excellent water retention properties slow down the drying process, ensuring adequate moisture and preventing cracks due to rapid dehydration. This is particularly valuable in hot or dry environments.
Application: Exterior wall plastering, floor leveling projects.

Solution 3: Enhancing Mortar Flexibility to Adapt to Deformation

Temperature changes or substrate expansion and contraction can lead to mortar cracking. HPMC improves mortar’s flexibility and elasticity, allowing it to withstand minor structural deformations without cracking. This is critical for projects requiring resilience to slight movements, such as high-rise buildings or bridges.
Application: High-rise building exteriors, bridge and tunnel mortar applications.

Solution 4: Optimizing Mortar Workability for Higher Efficiency

Good workability is key to construction efficiency and quality. HPMC enhances mortar’s flowability and plasticity, making mixing more uniform and application easier, resulting in a smoother finish. This saves labor effort, boosts construction efficiency, and ensures consistent mortar layer quality.
Application: Large-scale plastering, tile adhesion projects.

Solution 5: Improving Mortar Durability for Longer Building Life

Harsh environments, such as high temperatures, humidity, or freeze-thaw cycles, can degrade mortar over time. HPMC strengthens mortar’s internal structure, enhancing its resistance to environmental erosion, ensuring stable performance under extreme conditions. This extends building lifespan and reduces maintenance costs.
Application: Coastal region buildings, cold-climate foundation projects.

Solution 6: Eco-Friendly and Safe for Sustainable Construction

HPMC is a non-toxic, environmentally friendly additive that aligns with modern construction’s sustainability goals. Using HPMC in mortar and putty not only improves project quality but also minimizes environmental impact, contributing to healthier and greener building practices.
Application: Green building certification projects, eco-friendly residential developments.
