How to use Zemcoat Skimcoat – Original
1. Mixing
| MIXING RATIO (approx.) | |
|---|---|
| Water | Zemcoat Original |
| 0.32 L | 1 kg |
| 8 L | 25 kg |
NEVER mix old batch with new batch.
Pour water in a plastic pail and add Zemcoat Original. Mix 2 – 3 minutes
to attain a smooth and lump-free consistency. Let mixture rest for 15 minutes. Mix again briefly before use.
2. Application
While the surface is still damp, apply Zemcoat Original to desired application thickness (2 – 5mm) using a steel trowel. Zemcoat Original has set when the finish looks matte.To further smoothen minor unevenness the surface before painting, sprinkle a small amount of water before the surface is about to set, then smoothen with rubber float to desired finish with Zemcoat Super Fine or Zemcoat Water Resistant as recommended.
Dampen concrete surface before Zemcoat application.
- When using Zemcoat variants with the same color, apply Super Fine or Water Resistant just before Original is about to set.
- When using Zemcoat variants with different colors, apply Super Fine
or Water Resistant only after Original has already set.
TIP: Zemcoat has set when the finish looks matte. If needed, sprinkle a small amount of water when the surface is about to set, then smoothen to the desired finish.
3. Further Finishing
Zemcoat Original must receive further finishing as protection (e.g. paint, wall paper, concrete sealer, etc.). Cure 3 – 5 days prior to further finishing.
