Epoxy cement self-smoothing screed.
Sikafloor® 81 EpoCem is a three component, epoxy modified, cementitious self smoothing screed. It is particularly used as a base layer beneath Sikafloor® coatings, mortars, screed, timber flooring, carpets, tiles etc. When used in conjunction with an impervious top coat, it provides a surface mounted damp proof membrane system which can be applied to green and damp substrates.
Suitable areas of application:
Preparation:
The cementitious substrate should be sound and of sufficient compressive strength (minimum 25 N/mm²) and pull off strength (minimum 1.5 N/mm²).The surfaces must be dry and free of all contaminants e.g. oils, grease, surface treatments and coatings etc. The substrate must be prepared mechanically to achieve an open textured fine gripping surface, free of cement laitance. Weak concrete should be removed and surface defects such as blowholes and voids must be fully exposed. All dust, loose and friable material must be completely removed, preferably by brush and vacuum, from all surfaces before application of the coating. Repairs to cementitious substrates and filling of blowholes, levelling of irregularities, etc. should be carried out using an appropriate product from the SikaDur®, Sikafloor® or SikaGard® range of materials. Prior to application confirm substrate moisture content is <12% by weight or <95% RH.

Standard product features | Application: Spread to required thickness by trowel. Immediately work with spiked roller to ensure even thickness and release of entrapped air. If blinding with quartz aggregate, ensure that the minimum thickness of 2 mm of unbulked Sikafloor® 81 EpoCem is not compromised as this will impair its ability to act as a DPM system. |
