Step 1
Applications ㆍCan be brushed, rolled or troweled onto any surface that needs waterproofing, whether bare concrete, precast concrete, lightweight concrete or rough-surfaced tiles, without a primer. ㆍCan be applied anywhere around the house, such as roof decks, balconies, floors, walls, bathrooms, concrete water tanks, swimming pools, parapet curbs, etc. Surface preparation ㆍClean the surface so it is free of dust and oil stains. ㆍIf the surface has cracks or deep holes no larger than 3 cm, repair them with Beger Repair Mortar. ㆍSmooth, glossy surfaces must first be sanded with coarse sandpaper. ㆍAreas with mould or moss should be scrubbed clean and treated with Beger MouldFree M-001 mould and moss remover, then left to dry for 24 hours. ㆍDampen the surface thoroughly before applying the waterproofing product. Application ㆍMix Beger Flex Shield 2K at a ratio of 3.6 : 1 by weight, or 18 kg of Part A with 5 liters of Part B (for the best blend and performance, pour in the liquid followed by the powder, dividing each into 2 pours). ㆍMix with a low-speed drill (400-600 rpm) for about 3 minutes until uniform, then leave it for 1-2 minutes so the mixture is fully saturated. ㆍBrush or roll onto the surface while it is still damp, to a thickness of about >1.0 mm per coat. Beger Fiber Mesh fiberglass reinforcing mesh is recommended at wall joints to strengthen adhesion. Then let it dry for 3-4 hours before applying the 2nd coat. ㆍApply the 2nd coat in the opposite direction to the first, then let it dry for 3-4 days before use or before tiling (fully cured in 28 days). Additional recommendations ㆍSmooth, glossy surfaces must be sanded with coarse sandpaper to open up the surface before applying the waterproofing cement. ㆍWhen mixing, it is recommended to pour the liquid (Part B) first, followed by the cement powder (Part A), splitting both components into 2 pours each for the best working performance. ㆍMix with a low-speed drill at 400-600 rpm for no less than 3 minutes. ㆍThe total thickness of the 2 coats must be more than 2 millimeters. ㆍOnce mixed, use it all within 1 hour or less, depending on weather conditions. Storage ㆍStore in a dry place, free of moisture, at a temperature that is not too high, as this may cause the product to deteriorate. ㆍ The product has a shelf life of 1 year from the date of manufacture in an unopened container stored in a dry place
