Why are expansion joints needed? How to Use Bostik Liquid Cork Sealant?

When two floors are joined together, an expansion joint must be created and filled with a material that can resist compression and stretching. Since changes in temperature and humidity can cause the floors to expand or contract slightly, it's advisable to create a gap of 5-10 mm on the joint to help reduce stress between the floor surfaces.

The surface to be sealed should be clean, dry, and free of dust and debris. Apply Bostik 3070 using Liquid Cork Bostik 3070 Applicator Gun. Hold the nozzle about at the appropriate distance from the surface, apply the sealant, and then smooth out the surface. Use a spatula or other tool to smooth out the sealant and ensure a uniform coverage. Once the excess of cork sealant has been removed and levelled with a spatula, the area should be left to dry for 24 hours. Do not touch the surface or apply any additional coats until the sealant is fully cured.

A 500 ml tube of Bostik 3070 cork sealant is sufficient to fill an expansion joint with a volume of 500 cm³. For instance, if the joint is 1 cm thick, 3 cm deep, and 800 cm long, its volume would be 1 × 3 × 800 = 2400 cm³, requiring a minimum of 5 tubes to fill. The minimum quantity available for purchase is one 500 ml tube.
