COVERAGE:

Varies according to the substrate condition. Approximately 2m2 per litre of product.

PREPARATION:

The substrate should be free of dust, grease, wax, oil, dirt, loose plaster, laitance, curing compounds, paint and all other friable materials and contaminants likely to prevent the adhesive bonding. New concrete should be left with a wood float finish and sufficiently aged as per manufacturer’s recommendations. Smooth surfaces on new and old concrete should be scabbled. All substrates should be structurally sound, securely fastened and properly supported to eliminate any movement that may cause cracking. Dampen the substrate with clean water immediately before the application of CEMIX CEMKEY CONCENTRATE.
