QUICSEAL 509 is a specially formulated acrylic latex admixture to improve the adhesion of screeds, renders, patching and repair mortars to concrete and cement-sand substrates.
It is also used as an admixture for cement and sand mortars to improve the quality of screeds and renders. Once cured, the screeds and renders are resistant to water, mild chemicals and weathering effects.
Bonding agent for screeds, repair and patching mortars;
Improve the adhesion between new and old concrete.
Improve the water resistance and quality of screeds and renders/plasters for internal and external applications;
Improve the cohesion and adhesion strength of screeds and renders/plasters;
Adhesive slurries for bonding screeds and renders/plasters onto concrete, precast panels and waterproofing membranes;
Key (splash or spatter) coat before rendering/plastering;
Improve the strength of thin render/plaster coats;
Dampen substrate but without ponding water and then apply a coat of QUICSEAL 509 or an adhesive slurry coat (see section on Adhesive Slurries) to improve the adhesion of patching mortars to the substrate. While the bonding agent is tacky, immediately apply QUICSEAL repair mortars or non-shrink grout.
Approx 0.2 kg/m2 of QUICSEAL 509 is required for adhesive slurries, bonding aid and key coats.
Approx 1 kg/m2 of QUICSEAL 509 is required for screeds and renders for every 20mm thickness.
The quantity of QUICSEAL 509 for each application should be adjusted to workability depending on the application requirement.
