Mapei Mapeproof ESM Epoxy Damp Proof Membrane (Select Size)

DESCRIPTION

A two-component, solvent free, pure epoxy resin, used as a moisture vapour barrier on cement-based substrates containing high residual moisture.

It is a low viscosity product with a high penetration capacity in the porosity of the substrate. Because of the absence of solvents, and very low odour it can be used in inhabitated environments (e.g. hospitals, schools, offices, etc)

Application Procedure 1

Power Floated and New Substrates:

• The substrate should be abraded by mechanical means to remove any curing agents or contamination, to assist penetration and adhesion of the membrane.

• The area should then be thoroughly vacuumed to remove all dust and debris.

• Apply the first coat of Mapeproof ESM ensuring it is well worked into the substrate and that complete coverage of the area is achieved at a maximum rate of 20 m2 per 4kg unit (depends on the porosity of the sub-floor) and allow to cure (approx 5 hours).

• Apply the second coat of Mapeproof ESM at right angles to the first coat, again ensuring complete coverage.

• When the second coat has cured, a coat of Mapeprim SP or Eco Prim T primer should then be applied within maximum 24 hours (primer drying times vary with ambient conditions i.e. temperature and humidity).

• The levelling compounds should be applied within 24 hours of the primer application.

Application Procedure 2

Sand/Cement and Existing Substrates:

• All existing materials, adhesives, laitance and contamination should be removed prior to preparation work commencing.

• Any cracks in the substrate should be filled with Eporip.

• Where the substrate has a textured or profiled finish, Latexplan levelling compound should be applied to provide a level surface for the membrane to be applied onto
