All-in-One Wood Flooring Urethane Adhesive, Moisture Vapor and Sound Reduction Membrane

SikaBond-T21 All-in-One is a 1-component, low VOC, low odor, super strong, moisture-cured polyurethane adhesive for full surface wood floor bonding.

T21 can be used as a vapor retarding, crack-bridging and sound reduction membrane. A permanently elastic, super strong, very low permeability moisture-cure polyurethane adhesive for full surface wood floor bonding.

SikaBond-T21 may be used for solid and engineered wood floors (strips, longstrips, planks, panels, boards), mosaic parquet, industrial parquet, wood paving (residential) as well as chip boards and plywood.

Once cured, SikaBond-T21 will generate a super strong bond to a variety of substrates for glue down installations and at the same time form a membrane which reduces moisture vapor transmission from the subfloor and reduces sound.

Sika’s systems for wood floors consist of innovative products which contribute to sustainable construction solutions in many ways:

Superior Adhesion and Green Grab
SikaBond adhesives will develop a strong and durable bond to most types of woods.

Elastic bonding reduces the stress to substrates and guarantees a durable wood floor with long life time.

Easy Trowelability
Sika’s wood flooring products are smooth and easy to apply, preventing fatigue.

Fast Curing
Fast curing products shorten the application time, which enable contractors to finish their work in less time. Sika’s wood floor bonding adhesives allow sanding and finishing within 8 – 12 hours.
