20 Buckets of Sika SikaBond T21 Wood Floor Adhesive 4 Gallon

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

4 Gallon Container


SikaBond-T21 is a one-component, low VOC, permanently elastic, super strong, very low permeability moisture-cure polyurethane adhesive and vapor retarding membrane all-in-one for full surface wood floor bonding.

Coverage of approximately: 45-50 sq. ft./gal

Where to Use

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 to reduce moisture vapor transmission from the subfloor.
