What is waterproofing and why must every building be waterproofed?
Waterproofing is a solution that uses specialized materials to prevent water, moisture and chemicals from penetrating the concrete structure. Without proper waterproofing, a building easily suffers problems such as: leaks, concrete cracking, corrosion of steel reinforcement, reduced lifespan and large repair costs during operation.
When should waterproofing be carried out for a building?
Waterproofing should be carried out right from the initial construction stage for optimal effectiveness. In addition, buildings already in use but showing signs of water leakage can still be treated with specialized waterproofing solutions suited to each item.
Which areas must be waterproofed?
The items with high leakage risk include:
- Roof slabs, concrete roofs, exposed roofs
- Basements, basement walls, bottom slabs
- Bathrooms, wet areas inside the house
- Balconies, rooftops, podium floors
- Swimming pools, domestic water tanks, wastewater treatment tanks
What waterproofing solutions does Euro Paint Vietnam provide?
Euro Paint Vietnam provides comprehensive waterproofing solutions, including:
- Acrylic-based waterproofing for walls and lightly loaded areas
- Polyurethane (PU)-based waterproofing for floors, roofs and areas subject to vibration
- Polyurea waterproofing for items requiring high durability and chemical resistance
- HDPE preformed waterproofing membrane for basements and underground structures
Each solution is tailored to the actual conditions of the project.
How is PU-based waterproofing paint different from Acrylic?
Acrylic: water-based, easy to apply, suitable for vertical walls and areas with little movement.
Polyurethane (PU): highly elastic, good adhesion, resists vibration and structural cracking, suitable for roof slabs, balconies, swimming pools and bathrooms.
The choice depends on the specific item and its technical requirements.
What is Polyurea and when should it be used?
Polyurea is a premium 2-component waterproofing material, capable of:
- Fast curing
- Outstanding elasticity and chemical resistance
- Being suitable for elevated swimming pools, storage tanks and heavy industrial zones
Polyurea is often used for projects requiring a long lifespan and high safety.
Which solution should be used for roof-slab waterproofing?
For roof slabs, Euro Paint recommends the following system:
- Highly elastic PU waterproofing for non-exposed areas
- PU combined with a UV-resistant top coat for exposed roof slabs
- A 2-in-1 waterproofing & heat-proofing solution for residential and factory buildings
The solution is chosen based on the degree of exposure, the load and the usage requirements.
Can bathroom waterproofing be applied on a damp surface?
Yes. Euro Paint provides a product system that can be applied on damp surfaces with humidity up to 100% RH, with good adhesion on concrete, ceramic tile, natural stone, etc. – suitable for bathrooms and indoor areas.
Is the waterproofing solution for domestic water tanks safe?
Euro Paint’s waterproofing systems for domestic water tanks are designed to be:
- Non-toxic after curing
- Well-adhered in continuously damp environments
- Suitable for domestic water tanks and technical tanks
The application process is strictly controlled before the tank is put into use.
Does Euro Paint carry out the work directly or only supply materials?
Euro Paint Vietnam both supplies materials and provides technical consulting and application support, while also cooperating with a network of professionally trained contractors to ensure project quality.
What steps are involved in Euro Paint’s waterproofing process?
The standard process includes:
- On-site survey of the project
- Proposing a suitable technical solution
- Surface preparation and treatment
- Application following the correct technical process
- Inspection, water testing and acceptance
Does Euro Paint have a warranty policy?
Yes. Euro Paint applies a warranty policy according to each product system and construction item, together with a commitment to technical support throughout the usage period.
Does Euro Paint provide a waterproofing solution for roof slabs that are already tiled?
Yes. Euro Paint is a pioneer in providing an effective waterproofing solution on already-tiled roof slabs without chipping the tiles, thanks to the absolute moisture-resistant product EP-2WT Primer, which allows saturated humidity of up to 100% RH.
Does Euro Paint have any solution for applying Polyurethane waterproofing products during the rainy season?
Yes. Euro Paint is currently the only company on the market with the moisture-tolerant primer EP-2WT Primer, allowing saturated humidity of up to 100% RH. It ensures adhesion of the Polyurethane waterproofing layer to damp surfaces and helps speed up construction progress even during the rainy season.
