Product description
Microstone Pool Base is a two-component, elastic waterproof mortar for swimming pools, water tanks and walls exposed to water. Applied in three thin coats with mesh, it forms the waterproof base that is then covered by the Microstone or Microforce pool finish.
Sold as two components: the 25 kg powder (Component A) and the 20 L liquid (Component B). Each 25 kg bag is mixed with 9 L of Component B, so one 20 L drum serves two bags.
Supplied by Microstone UK, Newcastle-under-Lyme. Contact us for stock and lead time.
How it's applied
- Prepare — flat, sound, clean substrate; cement bases fully cured (≥28 days). Repair defects with Innirepair.
- Mix — pour 9 L of Component B and slowly add the 25 kg powder until smooth and lump-free. Rest 5 minutes.
- Apply — three coats at minimum thickness with a steel trowel, mesh embedded in the middle of the coating. 4–5 hours between coats.
- Finish — cover with the final pool finish; wait at least 28 days before filling.
Avoid application with risk of rain, frost, strong wind or direct sun. For tanks in permanent contact with water, allow to dry fully (<4% moisture) and wash with hot water before use.
