Surface preparation: The surface must be clean and free from factors such as dirt, oil, sludge, etc. that reduce adherence.
Application method: After the ISONEM A4 package is opened, it is mixed for 2 minutes until a homogeneous consistency is obtained. If dilatation or expansion joint is made, it is recommended that PE joint backer rod be placed in the joint before the application is made on it. It is recommended to use joint mesh in chamfer detail applications. ISONEM A4, is ready to use, is filled into the prepared surface by using a spatula or by a mastic pump. After filling, the surface is smoothed with a wet sponge. ISONEM A4 should not be applied more than 5 mm at a time.
