About this deal

For a proper tanking job you would use the 1:1:1, then next day 1:1 and render coat, then next day 1:1 then render coat, getting waeker as you come out finishing 3:1 sand opc. You would also have SBR in the render mixes as per spec on tub. Im an old skool plasterer ( 34 years old ) And when i am rendering i use sand,cement and waterproofer/feb. Sometimes i use wire ( render lathe to all you young spreads ). Ensure that your flooring is as strong as it can be when you coat it with the Bostik Cementone SBR Waterproofing And Strengthening Admixture 5L. This product is designed to toughen up screeds and floorings made of cement and mortar. This specially modified formula is able to accomplish this end result by improving the abrasion and chemical resistance of the screeds, renders and similar cement mixes while also strengthening them structurally and waterproofing them against moisture damage. The product is suitable to use for bedding, patching, pointing, tanking, waterproof rendering, flooring, bonding renders and suction control. Bostik Cementone SBR 25L is used to modify mortars, screeds and renders to improve mix strength and durability, reduce water penetration and improve salt resistance. Cementone SBR can also be used as a bonding agent for all cementitious system. It is compatible with ordinary Portland Cement, rapid hardening, sulphate resisting and high alumina cements.

It is an excellent all round primer and bonding agent and is especially suitable for external applications If coveering the surface, when you will seal it up and reduce the suction. Although you may have some 'green suction' if you scratch and finish with a day between coats I'm using porcelain tiles in the garden. It's quite a 'wet' garden due to run off from the neighbours land so I want to ensure that my tiles are properly primed (I've read that it's crucial with porcelain tiles). This will produce a very strong mortar (or concrete) and it may be considered that such a mortar is unnecessarily tough for the job in hand. F'rinstance, does a patio or light-use driveway really need a bedding mortar which sets like iron in next to no time? In such cases, it may be more reasonable to halve the suggested dosage. However, for pointing mixes, especially in high traffic areas, 200ml/kg can usually be justified. It toughens, waterproofs and improves chemical and abrasion resistance of renders, screeds and mortar

Ensure surfaces are sound, clean, dry and free from grease, oil, paint, laitance and loose materials. Key surfaces by scabbling, grit blasting or planning. If steel reinforcement is exposed on concrete, use a wire brush to remove rust and scale. Prime exposed steel with a bonding slurry and allow drying. Dampen porous surfaces thoroughly with water.
