PRO BLOCK™ MMS ECO

PRO BLOCK™ MMS ECO is a two-component, solvent-free, fast-setting, fast-curing, 100% solids epoxy-based moisture management one-coat sealer system that can be applied to damp or new concrete as early as 7 days old (see Suitable Substrates). PRO BLOCK™ MMS ECO protects finished flooring system up to 100% RH as per ASTM F-2170; sustains pH levels up to 14 as per ASTM F-710 and reduces moisture vapor emission rate of a concrete substrate up to 0.12 kg/m2 (25 lbs/1,000 ft2) per ASTM F-1869. The PRO BLOCK™ MMS ECO system applies easily with a squeegee or a roller, dries as little as 4 hours with up to a 25-minute working time and emits no VOC making it an environmentally friendly product. PRO BLOCK™ MMS ECO can also be used as a bonding agent for self-leveling toppings and self-leveling underlayments (up to 50 mm [2″] thick) when used with sand broadcasting.

Approximate Coverage

Surfaces sealed with PRO BLOCK™ MMS ECO must be primed with PRO SUPERPRIME™ or PRO SUPERPRIME™ 1C to create an adequate bonding surface for self-leveling underlayments and toppings, cementitious screeds, patching compounds, and most floor covering adhesives (see respective technical data sheets for details). PROMA requires using sand broadcast to create an adequate bonding surface for self-leveling underlayment applications above 25 mm (1″) thick when installing over PRO BLOCK™ MMS ECO. Reference the chart below for guidance. Note that coverages given are approximate and can vary with concrete surface profile, porosity, and texture.
