Some structures get wet from the outside, some from the inside, and some can only be reached from the dry face. ACTFLEX 988 CWP is made for all three.
Where it goes
- Basements, retaining walls and lift pits.
- Water tanks, swimming pools and reservoirs.
- The inside face of a wall when the wet side cannot be reached.

Three rules
- Stop running water first. Plug active leaks with ACTFLEX HYDROPLUG before the membrane.
- Primer is usually not needed on sound, prepared concrete. Use ACTFLEX EP250 on burnished, very rough or dense concrete.
- Cover it within 5 days. It is not a finish and not made for sun or traffic.
