Application

Ensure that the substrate is properly prepared. All surface contamination such as dust and loose material should be removed, and the surface thoroughly cleaned before application of Sikadur 31+.

Concrete, masonry, stone and mortar surfaces should be prepared mechanically using suitable abrasive blast cleaning, needle gunning, light scabbling, bush hammering, grinding or using other suitable equipment to achieve an open textured, gripping surface profile. Concrete and mortar must be at least 3–6 weeks old.

Steel surfaces should be mechanically prepared using suitable abrasive blast cleaning, grinding, rotating wire brush or other suitable equipment to achieve a bright metal finish with a surface profile to satisfy the necessary tensile adhesion strength requirement.

Wood surfaces should be prepared by planing or sanding.

Always follow the application instructions for the specific substrate being repaired. Full application details can be found on the product data sheet.
