SecilTek Reabilita Cal AC Finish

SecilTek Reabilita Cal AC is a blend of natural hydraulic lime and carefully selected aggregates. It is a dry bagged product – just add water.

Use as a finishing coat in the renovation and rehabilitation of exteriors  and interiors on old masonry. It is also used as designated finish for cork board insulation systems where a light sandy sponged finish is desired.

Suitable for new or old rendered surfaces as a finishing layer in conservation and renovation. The use of natural lime binders, and their special composition, results in an excellent physical, chemical and mechanical performance.

Its thixotropic adhesion and permeability properties means it is particularly suitable for use over old rendered substrates.
