Microcement — technical data

Microrock Base

Two-component microcement base

Manufacturer Cemher
Country of origin Spain
System family Microcement
Supplied and applied by Earth Layers by Conmarble

The product

The base coat of the Microrock system: two layers at 2 to 3 mm total. Because the Microrock line is highly waterproof, no pore filler is needed before sealing.

Where it is used

Base coats under Microrock finish coats Interior floors and walls

Substrates

Substrate with minimum 25 N/mm² compressive strength and minimum 1.5 N/mm² pull-off Dry and clean of greases and contaminants No primer to be used — consult the technical department for poor, crumbled or damp substrates

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.

Type Two-component polymeric microcement — Comp. A paste, Comp. B hardener
Applied thickness 2 – 3 mm total in two layers, 1 – 2 mm per layer
Drying time Approximately 6 to 8 hours
Packaging 10 kg Comp A + 1 kg Comp B; 5 kg Comp A + 0.5 kg Comp B
Pore filler Not required — the Microrock line is highly waterproof
Data sheet revision 15/01/2018

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.

Do not use any primer under this product Substrates in poor condition or with moisture problems must be referred to the manufacturer's technical department Requires a water-based or solvent-based sealer over
