Roll-On Liquid Barriers
That Seal Tight and Set Right

Fighting moisture coming through the concrete can mess up your whole timeline. We carry roll-on barriers that solve the problem with a liquid seal that truly sticks.

No matter the moisture problem, we make sure you solve it quickly and hassle-free.

Frequently Asked Questions

Someone got the subfloor wet, can we still install?2022-10-31T14:41:51+00:00

You would be able to use a liquid roll on moisture barrier. Liquid moisture barrier is able to be 100% moisture blocking and as little as 85%.

How do I roll out the moisture rolls?2022-10-31T13:57:43+00:00

You would want to overlap the papers/palstics on each side to ensure slower transmission of humidity. For specific information go to the manufactuerers or architects page.

Is roll on or overlay moisture barrier better?2022-10-31T13:31:50+00:00

Each option does the job effectively. However, if you have RH of over 85% on the floor or a higher than nromal moisture reading it is ideal to use a moisture blocker that overs 85%+ or higher moisture contents. The liquid barriers are superior if you have a space with 85% or 10+ moisture.
