The Rubber Guard NS Non-Skinning Butyl Rubber Sealant from Everkem Diversified Products comes in a 10.1 oz cartridge and delivers a durable, waterproof bond that stays permanently flexible. This grey butyl sealant meets ASTM-C919 standards and maintains low VOC content at 100 g/L, making it suitable for interior and exterior sealing applications.
The non-skinning formula adheres to most building materials without forming a surface skin, which makes it ideal for applications where you need ongoing flexibility. You can use this sealant in STC-rated assemblies as an acoustical sealant, helping with sound dampening in wall and ceiling systems. The EcoSeal formulation keeps environmental impact low while delivering the performance you need on the jobsite.
This butyl sealant works well for sealing gaps in concrete, masonry, metal, and wood surfaces where movement is expected. The permanently flexible nature means it won't crack or lose adhesion when building materials expand and contract with temperature changes. Made in the USA, it's ready to use straight from the cartridge with standard caulk guns.
