Delta LM 800 Liquid Membrane is suitable for damp proofing, gas proofing and waterproofing a variety of substrates including concrete, masonry and metal, above and below ground level including retaining walls, cast concrete, precast concrete and steelwork.

Designed for use in applications where combined damp proofing and gas protection are required. Delta LM 800 can be applied by brush, roller or airless sprayer. Apply first/ priming layer at rate of 0.5kg/m² ensuring that coating is applied evenly over the surface. Allow first coat to fully dry, drying times may vary due to ambient conditions. (Product will change colour from light grey to black when dry). Apply second coat at rate of 0.5kg/ m², where there are joints or uneven surfaces a 3rd coat may be required. Protect application from frost and rain until application is fully dried and cured. Application should only be made when air and surface temperature is 5°C and rising.
Total application thickness should not exceed 4mm and should be at least 1mm.
