Varies according to the substrate condition. Approximately 2m2 per litre of product at a bed thickness of 1.5mm. A minimum of two coats is recommended to achieve this bed thickness.
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 recommendations.
All substrates should be structurally sound, securely fastened and properly supported to eliminate any movement that may cause cracking.
The substrate should be dry.
1. Stir before use.
2. Apply to the surface generously and evenly, using a medium brush.
