D4 strength wood glue that sets hard in 30 minutes. It foams slightly and is waterproof, making it suitable for interior and exterior use. Ideal for larger applications or workshop use where greater economy is required. Conforms to EN 204. The polyurethane material is strong and resilient to acids and chemicals. Rain and seawater have no effect on adhesion, and hot weather just makes the glue flow easier from the bottle. When pressured into a joint, the glue hardens and fills any and all gaps to prevent creaking and squeaks. Also provides gap filling properties. Professional grade and thixotropic. Brown in colour. 750g bottle.
