Common Mistakes When Installing Lightweight Bricks in the Rainy Season

The rainy season often presents a major challenge in construction projects, especially when installing lightweight bricks. Although more practical than red bricks, lightweight bricks still require ideal conditions to ensure strong, crack-resistant walls. Let's learn about common mistakes made when installing lightweight bricks during the rainy season—so your project can run smoothly without any weather disruptions!

1. Not Storing Lightweight Bricks in a Dry Place
Lightweight bricks easily absorb water. If stored directly on the ground or in an open area without cover, rainwater can dampen them and even saturate them. This reduces the adhesive power of the mortar.
Solution: Store lightweight bricks in a protected location, cover them with boards or pallets, and cover them with a tarp to protect them from direct rain.

2. Using Wet Bricks
Lightweight bricks that haven't completely dried after being exposed to rain can interfere with the adhesive power of instant mortar. When water remains in the pores of the brick, the mortar won't adhere properly.
Solution: Ensure lightweight bricks are completely dry before installation. If they are already wet, let them air dry for at least a few hours before use.

3. Mortar Mix Not Adapted to Weather Conditions
During the rainy season, many builders add too much water to the mortar to make it easier to apply. However, mortar that is too thin can cause hairline cracks and weaken the wall.
Solution: Follow the mixing instructions on the mortar product. Use high-quality mortar that dries quickly even in humid conditions.

4. Not Allowing Sufficient Drying Time
Rain can slow the drying process. If work continues without waiting for the mortar to dry completely, the risk of the wall tilting, cracking, or collapsing increases.
Solution: After installation, avoid covering the wall with plaster or paint too quickly. Allow the lightweight bricks and mortar to dry completely first.

5. Not Protecting the Work Area from Rainwater
Leaving work exposed without protection often results in rainwater directly hitting the newly installed wall. In addition to disrupting the adhesive strength, this can also cause uneven wall color or discoloration of the mortar.
Solution: Use a temporary cover (tarpaulin or plastic canopy) over the work area to keep it dry during the installation process.

Conclusion
Installing lightweight bricks during the rainy season is actually still possible as long as proper planning and site protection are carried out. Avoid using wet bricks, mix the mortar properly, and protect the work area from direct rainwater to ensure the walls remain strong and neat.
