Substrate preparation

Reactive Floor Moisture Barrier

Plan substrate preparation, priming, moisture control and levelling before the final floor finish.

Reactive Floor Moisture Barrier is a system component applied to prepared concrete to control the effect of residual moisture on a subsequent adhesive or floor coating, within limits permitted by the product and confirmed by testing. It is not a universal substitute for resolving active water ingress, hydrostatic pressure or structural waterproofing defects. Test method, allowable moisture level, preparation, number of coats, coverage, cure and compatibility with the next layer must be verified from current technical data and the project specification.

Selection and technical review

Provide the concrete or screed type, strength, moisture measurement, surface profile, existing finish and planned top layer. Primers, moisture barriers and levelling products do not perform the same function. Verify application limits, thickness, consumption and recoating intervals against the current TDS/SDS for the supplied product.

Application and handover preparation

Assess weak layers, contamination and old residues using an appropriate method; detail cracks, joints and active water problems separately. Record preparation checks, the trial area, batch and application conditions. Determine next-coat timing and compatibility from the technical system instructions.
