Roof waterproofing not done well? Be careful that your home does not turn into a "water curtain cave"!

During the rainy season and typhoon season, there are always some "little surprises" on the roof of your home? Water marks, leaks, and wall cancers appear one after another, which not only affect the comfort of the home environment, but in serious cases may even damage the building structure, making the home full of dangers.

If you want to avoid these annoying problems, waterproofing your roof is absolutely key!

Why is roof waterproofing so important?

• Prevent water leakage and wall cancer

When moisture penetrates into the building structure, it can easily cause the walls to mold, peel, and even form wall cancer, affecting the quality of living.

• Save high repair costs

Rather than having to do repeated repairs, waterproofing in advance can reduce long-term maintenance costs.

• Keep your home dry and comfortable

Excessive moisture not only causes furniture to mold, but may also affect your health.

• Extend building life and ensure safety

Long-term moisture erosion of structures will reduce the durability of buildings and affect living safety.

Analysis of the types of roof waterproofing materials

1. Film-coated waterproof material (suitable for DIY, simple construction)

This type of material is applied to the surface like paint and dries to form a waterproof layer.

• Acrylic waterproof glue: cheap, but easy to crack and requires regular maintenance.
  
  

  
  

• PU waterproof material: good waterproof effect and long life, but high construction requirements.

2. Permeable crystalline waterproof material (waterproof from the inside)

This type of material can penetrate the interior of building materials, fill small gaps, and form a waterproof structure.

• Silicate cement: Effective in preventing wall cancer, suitable for repairing old buildings.

3. Laying waterproof material (large area waterproofing, professional construction)

This type of material is directly covered on the surface and is highly waterproof and durable.

• Fiberglass: High durability, but more difficult to construct.

4. Sandwich waterproof material (waterproof + beautiful)

This type of material is sandwiched between the surface and the building materials and is suitable for balconies, bathrooms, etc.

• Elastic cement: can be used for tiling, but is not suitable for long-term exposure.
  

• Rubberized asphalt: easy to construct, but the waterproof ability is average.

5. Fill with waterproof material (necessary for repairing details and finishing)

• Waterproof silicone: strong adhesion and good waterproofness, but some materials cannot be painted.

• PU caulk: Suitable for various surfaces, but may change color due to long-term sunlight exposure.

[Recommended] Magical coating that can achieve waterproofing and heat insulation at the same time!

Traditional waterproofing projects usually require waterproofing first and then an additional insulation layer, which is time-consuming and labor-intensive. But now there is an "inorganic crystal mineral thermal insulation waterproof material" that can achieve both waterproof and thermal insulation effects with just one construction, greatly improving construction efficiency!

Construction steps:

1️⃣ Floor cleaning: Scrape off the old waterproof layer and remove sand, gravel and dust.

2️⃣ Fill the gaps: Use caulking materials to repair the corners and threshold seams.

3️⃣ Apply primer: fill the pores of cement and improve adhesion. 

4️⃣ Application of main materials: Use spraying or troweling to apply evenly. 

5️⃣ Apply protective topcoat: increase the durability and self-cleaning effect of the waterproof layer.

6️⃣ Water test: Make sure there is no leakage.

Don’t neglect roof waterproofing to make your home more secure!

Rather than waiting until it rains a little at home to remedy the situation, it is better to take action now and waterproof your roof. Whether you DIY or hire a professional team to do the construction, choosing the right waterproof materials can make your home environment more comfortable and you feel more at ease!

Only by choosing the right waterproof coating and following the correct construction method can you ensure long-lasting waterproof effect.
