Microcement — technical data

Micropool

Two-component microcement for immersed surfaces

Manufacturer Cemher

The product

The immersion-rated microcement in the range. Where Microdur Plus is expressly excluded from pools, Micropool is the product that carries the water-penetration and 28-day no-pressure results a pool detail needs.

Where it is used

Swimming pools and immersed surfaces Pool surrounds and wet decks Interior floors and walls where a matching finish is required

Substrates

Concrete and cementitious substrates, consolidated and true Dry, clean and free of dust, grease or dirt

Application data

Coverage, thickness, mix and cure, as declared by the manufacturer. Site conditions in the Gulf sit at the top of most of these ranges — allow for it in the programme.

Where not to use it

The limits are as much a part of the specification as the performance. Everything here is stated on the manufacturer's data sheet.

Not over electric underfloor heating Sensitive to vinegar and other organic acids Contains silica — respiratory protection required when sanding Reaction to fire is Class B, lower than the A1 of Microdur Plus and Microtadelakt Performance figures marked 1* are measured without sealer
