Surface preparation

Surfaces must be clean and free of dust, dirt or other contaminants.


During colder periods, keep the product in a temperate place to facilitate its application. Do not apply if rain is expected. 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. To glue back shingles, apply only 3 dots about 25mm (1 ") spread evenly over the shingle. 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 4h for surface drying and about 48h for complete drying. The drying time depends on the application method, the ambient temperature, the surface and the thickness applied.
