ARDEX AF 145 can be used as a Wet Set or a Pressure Sensitive Adhesive. As a Pressure Sensitive, there's nothing quicker. Once spread, it reaches its pressure sensitive stage in as little as 20 minutes, which is twice as fast as other products on the market. Once it has reached its pressure sensitive stage you’ve got up to 80 minutes to fit your flooring. Plus there's no need to roll the adhesive ribs either... simply fit your floorcovering and finish with a heavy roller 👍 If you want to use ARDEX AF 145 as a Wet Set, simply spread the adhesive and leave it to air for 5 minutes before fitting. So whether you prefer to work with a pressure sensitive or a wet set adhesive, with ARDEX AF 145, the choice is yours.
