MasterSeal 521 - A polymer modified cementitious, durable, waterproof coating
Description
MasterSeal 521 is a two-component, polymer modified, cementitious coating that requires only on-site mixing to form the ideal product to provide a durable, waterproof coating to re-surface concrete, masonry, and most other construction materials.
MasterSeal 521 imparts the natural
concrete appearance.
Where is MasterSeal 521 applied?
- To re-face and even out variations in
concrete surfaces
- As a waterproof coating for water-retaining
structures like water tanks, pols, resevoires
etc.
- To provide foundation protection
- As a backing to marble and granite to
prevent water ingress, and thus alleviate
surface staining
- To provide protection to concrete surfaces
from carbonation and chloride attack
For use on pedestrian walkways in marine
areas
What are the advantages of MasterSeal 521?
- Excellent adhesion – bonds to porous and
non-porous surfaces
- Limited flexibility
- Suitable for light pedestrian traffic
- Breathable – whilst repelling water, allows
substrate to breathe
- Slurry or trowelable consistency;
application is still possible by spray
Unlike conventional coatings, which require
a 7-28 day cure of concrete
- MasterSeal 521 can be applied to 24 hour-old
concrete, thereby giving immediate protection
