Preparation of the base and method of application:

• The substrate must be sound, free of dust, dirt, loose particles, surface contaminants such as oil, grease, cement laitance and others.Cleaning can be water jet or sandblasting, mechanical or manual roughing.
• Shock/vibration-free cleaning methods are recommended
• Damaged, layered or weak concrete must be repaired using a suitable material
• The surface is wet to saturation.The wetted surface should acquire a dark matte appearance without shining, and there should be no water on the surface.
• Apply the first layer with a notched trowel (3 x 3 mm) on a flat base. Leave the first layer rough for better adhesion of the second layer.
• Once the first coat has hardened, apply a second coat of SikaTop Seal107 with a smooth trowel across the first. SikaTop Seal 107 can also be sprayed with a pump suitable for fine solution.
• When used as a protective coating on hard substrates, such as reinforced concrete, SikaTop Seal 107 can be applied without reinforcement with fiberglass mesh
• Ceramic tiles and glass mosaic tiles can be placed on SikaTop Seal 107 using a suitable cementitious tile adhesive
• The maximum recommended thickness of each layer is 2 mm
• For waterproofing and protection of concrete, the correct application thickness is at least 4 mm, applied in 2 layers
