Isopropanol for glazing applications (due to possible streaking of Sika® Aktivator-205 on glass)
1.3 Product Technology
The recommended pre-treatment for all products (exceptions see above) can be found in the pre-treatment tables. As the recommended pre-treatment may be different among technologies there is one column for each of them. Please make sure to choose the recommendation from the correct column. The following table lists some products for each technology. For all product not mentioned below the technology, the recommended pre-treatment can be found in the product data sheet (PDS).

2 Pre-treatment Chart for Construction Sealants
Precondition: Surfaces must be clean, dry and free from oil, grease and dust, loose or friable particles. Cement laitance has to be removed. Grinding the surface of non- porous substrates with an abrasive pad very fine may improve the adhesion performance. It is recommended to verify compatibiility with the cleaning products.
