Consumption
Depends on the substrate roughness and thickness of layer applied. As a guide, 1 bag yields approximately 13.0 litres of mortar
MIXING
Place the water into a forced action mixer or in a clean drum. Slowly add complete bag of Sika MonoTop®-130 Seal into the water and continuously mix for 3 minutes in mixer to achieve a uniform and lump free consistency. Alternatively use a slow speed drill (200-500 rpm) and spiral paddle mixer.
APPLICATION
Pour the mixed mortar into the header box/hopper ensuring continuous material flow during the complete operation to avoid trapping air. Use steel banding or chains to assist flow where necessary. For large volume placement, pumps are recommended. For cold weather working consider using warm water to assist with achieving strength gain & other physical properties.
CURING TREATMENT
After the mortar has initially hardened, remove formwork and trim edges while concrete is ‘green’. Protect the fresh material from premature drying using appropriate curing method e.g. curing compound such as Sikafloor® ProSeal ,moist geo-textile membrane, hessian, polythene sheet etc. In cold weather apply heat blankets to maintain a constant temperature.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened/cured material can only be mechanically removed.
