Acousti-Mat® LP/LPR Installation Guidelines

Acousti-Mat CLP  .  Acousti-Mat CLP Acousti-Mat LP is the low profile sound control solution.  If applied to a gypsum underlayment, the gypsum underlayment must be sealed before adhesive is applied
1. If Acousti-Mat LP or LPR is installed over a Maxxon Underlayment, the underlayment must be sealed prior to adhesive application using Maxxon Overspray or Maxxon Acrylic.   Acousti-Mat LP offers acoustical control in concrete construction
2. Acousti-Mat LP Adhesive is rolled out over clean and contaminant free concrete. Over rough concrete surfaces, a slurry of Maxxon Underlayment should be utilized.   Acousti-Mat LP offers acoustical control in concrete construction
3. Acousti-Mat LP or LPR is then placed into wet adhesive or slurry. Seams should be butt jointed or overlapped, depending upon the topping application.           Acousti-Mat LP offers acoustical control in concrete construction
4. Once adhesive sets, back roll Acousti-Mat LP or LPR to ensure that 100% surface contact is achieved with adhesive or slurry application.  

Acousti-Mat LP Installation
5. Isolation strips are installed around all walls, columns, and floor penetrations to eliminate flanking paths. Acousti-Mat LP Isolation Strips can also be utilized to cover any exposed concrete between seams in the Acousti-Mat LP or LPR.


Pouring a gypsum underlayment
6. Acousti-Mat LP or LPR is topped with an approved Maxxon Underlayment. For uniform depth and a smooth surface, installers use a screed to finish the underlayment surface. In as little as two hours after the underlayment has been poured, the floor is hard enough to accommodate foot traffic.
