Rockmax Crystalseal is a crystallization waterproofing system based on cementitious slurry form. It consists of a selected silica aggregates, quartz sand, chemical additive and portland cement. Rockmax Crystalseal is full fill pore and capillary in concrete surface after chemical reaction develop. Rockmax Crystalseal withstand hydrostatic water pressure and permanent waterproofing system
AREA OF USES
APPLICATION AND INSTALLATION
Concrete substrate must be sound, clean, free from oil, grease, mould oil, dust, loose particles and cement paste. Check and investigate void, honeycomb, or crack on concrete substrate. All damaged concrete must be repair prior to application. Saturated surface by spray water at least 2-3 hours prior application. No water standing on surface. Damp surface will allow chemical of Rockmax Crystalseal penetrate deeply into concrete.
Mixer must use low speed drill mixer (500 rpm) with and including good quality steel paddle. Make sure all tools and equipments are in good conditions and clean. Add Rockmax Crystalseal (25kg bag) slowly into 7-8 litre of clean water. Mixing continueous approximate 3-5 minute until homogeneous. Do not add additional water to rework. It recommended to mix the whole set a time to achieve all mixture chemical in one bag.
Apply Rockmax Crystalseal by plastic brush with approximate coverage rate 1-1.2kg/m2/coat. Two coat application is recommended. Allow 2-4 hours to dry between coats.
Coverage rate: 1.0-1.2kg/m2/coat
Number of coats: 2 coats
Allow Rockmax Crystalseal curing by spry clean water with approximate 2-3 days after dry and 3 times a day at minimum. Protect with plastic sheet to prevent drying up is prefer.
