Berger's solvent-free self-levelling epoxy screed is ideal for covering up imperfections and unevenness on concrete substrates. The Pro Epishield floor SL screed provides the correct treatment for applying a self-levelling top coat. It gets sandwiched between the floor coating primer and the final top coat finish, giving the overall coating a high compressive strength and abrasive resistance. Not all surfaces require the SL screed coatings, but it is highly recommended when the floor is subjected to high load-bearing movement. The recommended coating thickness is 1mm - 3mm.
