THE MORE BEAUTIFUL THE FRONT HOUSE IS - THE MORE EASILY IT IS SUFFERED BY LEAKS

Modern street-front houses - tube houses are often heavily invested in aesthetics:

- High quality decorative tiles.

- Stepped architecture, balcony, sunshade louvers.

- Heat-resistant paint, 2 layers of insulation.

But why, after only 1-2 years, do those houses start to leak water, peel off paint, turn yellow, and get moldy?

What is the cause? This article will help you clarify and find a thorough facade waterproofing solution.

1. Why Are Front-Facing Houses Prone to Leakage?

1. The facade is the area most affected by the weather.

- Exposed to wind, sideways rain, direct sunlight.

- No awning or shade trees.

- Joints and wall edges are prone to cracking over time.

2. Prioritize aesthetics, omit waterproofing

- Homeowners often focus on tiles, decorative stones, and paint color combinations, but few people thoroughly waterproof the base layer before plastering. Or it could be because they choose waterproofing materials that are not suitable for the hot and humid climate in Vietnam.

3. Incorrect waterproofing techniques or lack of primer when installing stone or tile

- Not treating the waterproof lining causes water to seep under the tiles.

- Poor quality outdoor tile adhesive.

- Not treating the expansion joints at the base of the wall carefully.

3. Technically Correct Facade Waterproofing Solutions

In case of not yet built / under construction:

-Before plastering or tiling: apply a layer of cement-based waterproofing membrane (Sikatop seal 109) combined with a layer of penetrating crystalline waterproofing membrane (this layer is on the inside) and then tile.

- At the joints between the balcony and the wall: Seal with Sikaflex Construction glue combined with water-stop tape.

In case of leakage:

- Lightly absorb: scrape off the paint layer, apply a reverse waterproofing layer from the inside or from the outside with elastic material.

- Heavy seepage: must remove tiles, re-treat waterproofing layer from the base, then re-tile.

4. Notes When Waterproofing the Facade

- Do not believe in "waterproof paint is enough" - paint is only a protective layer, not a root cause of water seepage.

- Waterproofing should be done right after the cement plaster layer - before painting or tiling.

- Note technical slots, circuit breakers, wall bases, and outdoor technical boxes.

- Facade waterproofing is a category that should be hired by a professional construction team. Do not hand over the entire package to a contractor if you cannot supervise.
