To repair joints and cracks, firmly apply enough product in depth to fill all the cavities and close the gaps. Apply the product in a slight excess above the surface to avoid water accumulation. Close the container after each use. For the caulking tube, cut the nozzle tip at 90° to obtain a bead between 6 to 12 mm (1/4 to 1/2 inch). Perforate the seal inside the nozzle.


Allow about 1h for surface drying and about 24h for complete drying. The drying time depends on the application method, the ambient temperature, the surface and the thickness applied.
