ZEMCOAT Water Resistant is a specially formulated skimcoat for super fine plastering applications. This specific Zemcoat variant not only smoothens minor unevenness (0.5-2mm) but also prevents the penetration of moisture, hence paint blistering is avoided. Ideal for application areas that need additional protection against rain or moisture, such as facade, bathroom, kitchen, firewall, etc.
PROPERTIES
- Water resistant to protect against moisture absorption & mold growth
- Prevents paint delamination & blistering due to water resistancy
- Superior Bonding
- Ultra thin application to perfectly smoothen minor unevenness of concrete & plastered surfaces
- Prevents hairline cracks & pinholes
- High initial adhesiveness and non-sag properties make it ideal for overhead application
- Economical due to reduced construction & labor costs
- Compatible with masonry paint, concrete sealer, etc.
- Direct application on indoor & outdoor concrete surfaces
- Eco-friendly (low Volatile organic compound levels)
Surface Preparation
Concrete surface must be cured, structurally stable, clean & free of paint and contaminants such as dirt, dust, loose material, oils, chemicals, etc
Caution: For outdoors & during hot weather conditions (noon time or summer), wet substrate well to ensure proper bonding.
Substrate Surface Preparation
New concrete Concrete must have cured 7-15 days

How to use Zemcoat Skimcoat – Water Resistant
1. Mixing
| MIXING RATIO (approx.) | |
|---|---|
| Water | Zemcoat Water Resistant |
| 0.35 L | 1 kg |
| 7 L | 20 kg |
Pour water in a plastic pail and add Zemcoat Water Resistant. Mix 2 – 3 minutes to attain a smooth and lump-free consistency. Let mixture rest for 15 minutes. Mix again briefly before use. (NEVER mix old batch with new batch.)
2. Application
While the surface is still damp, apply Zemcoat Water Resistant to desired application thickness (0.5-2mm) using a steel trowel. Zemcoat Water Resistant has set when the finish looks matte.
To further smoothen minor surface unevenness before painting, sprinkle a small amount of water before the surface is about to set, then smoothen to desired finish using a rubber float. (Dampen concrete surface before Zemcoat application.)
- When using Zemcoat variants with the same color, apply Water Resistant just before Original is about to set.
- When using Zemcoat variants with different colors, apply Water Resistant only after Original has already set.
3. Finishing
Zemcoat Water Resistant must receive further finishing as protection (e.g. paint, wall paper, concrete sealer, etc.).
Let it cure for 3 – 5 days prior to further finishing. (Cure 3 – 5 days)
