Acoustilay TILEMAT: the latest member of the Acoustilay family – specifically designed for installation under ceramic and stone floor tiles. Acoustilay Tilemat can be used in new build, conversion and refurbishment projects manufactured from recycled rubber and EDPM.

Acoustilay Tilemat is designed to give long lasting impact sound insulation performance whilst giving sufficient stability for ceramic or stone tile floor finishes.

When tested beneath a ceramic tile floor finish on a concrete floor structure Acoustilay Tilemat improved the impact sound insulation performance of the floor from 66dB to 53dB.

General Notes

There are a vast number of floor finishes available and the installation guidance in this data sheet is given in good faith and to the best of our knowledge. The final decision regarding the compatibility of any floor finish installed onto Acoustilay Tilemat must remain the responsibility of the flooring contractor/installer. If in any doubt, please seek advice from the floor finish manufacturer.

Good practice applies in all cases. Prior to installation of Acoustilay Tilemat the floor should be level, clean and dry. Acoustilay Tilemat should be allowed to acclimatise to site conditions prior to installation.

Acoustilay Tilemat should be acclimatised to ambient conditions within the room at least 24 hours prior to fixing. Rolls should be unwound and allowed to relax. Acoustilay Tilemat should be cut to room dimensions ensuring that the joints run horizontally to any floor joint runs. Ensure the surfaces are clean, dry, levelled and smooth before applying approved Acoustilay Tilemat Adhesive. Allow the adhesive to fully cure for at least 24 hours prior to the installation of ceramic or stone tile flooring.

Lay ceramic or stone tile flooring onto Acoustilay Tilemat using Mapei Elastorapid 2 Part Adhesive. Grout tiles using an approved cementicious grout with flexible additive. Avoid point and impact loading of the floor for at least 3 days after installation. Ensure that a 5mm isolation joint is achieved to all perimeters and sealed using SRS acoustic sealant.
