There are several causes of the cracks in the concrete surface and plaster walls, including inappropriate curing times, impurities in the aggregates, higher water-to-cement ratios, and building settlements etc.
There are several procedures involved in painting and sealing concrete or plaster cracks. Here is a basic guide to assist you with the procedure :-
APPLICATION INSTRUCTIONS
Surface Preparation (crack-free-concrete)
- The surfaces to be adhered to need to be completely dry and clean.
Application
- Clear all loose material from the cracks by cleaning them. To determine the crack’s true breadth and depth, it must be expanded if it is too fine. Make sure there is no grease, oil, or dust on the surface.
- Apply cement based non shrink or acrylic based cracks fillers as per the manufacturer instructions.
- With a putty knife or spatula or sealant gun machine fill into the crevices or cracks.
To achieve a clean and smooth surface, use a putty knife to level the area. Following a full day, painting can begin once filled materials has fully cured.
Safety Precautions
- Keep out of children’s reach. Put on gloves, appropriate safety gear, and eye and facial protection. Wash with lots of clean water right away after skin contact. If something gets in your eyes, wash them right away with lots of clean water and get medical help.
