Dyna-Stix® STP is a versatile 4 in 1 silane terminated polymer adhesive designed for use on high moisture slabs. It is ideal for installing multi-ply engineered wood, high-density fiber board core wood, acrylic impregnated wood plank, finished and unfinished solid wood flooring (with manufacturer approval for glue down installations), parquet, and bamboo over properly prepared substrates. When installing solid wood flooring directly to concrete substrates, follow NWFA guidelines. Dyna-Stix STP should not be installed over existing VCT, vinyl sheet, plank, tile, or other resilient flooring. This adhesive features MicroSept® Advanced Antimicrobial System to protect against bacteria and fungal growth and is FloorScore® certified for indoor air quality. Dyna-Stix STP meets code requirements for sound reduction per ASTM E90-09 and ASTM E413-10, achieving over 55 decibels.
