RLA Rapid Screed is a fast setting high build modified cementitious screed for use with RLA waterproofing membranes and tile adhesives.
The specially selected cements and polymers contained in RLA Rapid Screed produce a fast setting underlayment with exceptional adhesion to most prepared flooring materials. It can be used for internal/external applications but not for permanent immersion (e.g. swimming pools). It is ideal for use in shower bases to create correct falls, also suitable for use on balconies as long as the correct falls are adhered to and covered with a waterproofing membrane.

- RLA Rapid Screed has a work time of approximately 30 minutes at 25°C
