WPA SPUR

WPA SPUR is a high quality, professional, universal, low modulus sealant based on hybrid technology. WPA SPUR cures under the influence of atmospheric moisture and is free of solvents and isocyanates with a very low VOC content. When cured it forms a tough, flexible seal and bond, capable of cyclic expansion and compression movement. Joints or fabrications formed with this sealant can be expected to extend and compress a total of 50% (± 25%) of original joint dimensions to ASTM C719.

​
