Highlights
- Cementitious waterproofing slurry that bonds strongly to masonry and concrete, providing durable tanking for internal and external walls while allowing the structure to breathe and blocking damp and efflorescent salts.
- Suitable for above-ground walls and basement tanking up to 600 mm, offering reliable protection across interior, exterior, and lower-ground applications.
- Mixes in just three minutes and applies easily by trowel, brush or sprayer; once cured, the coating is frost- and heat-resistant for dependable performance in domestic or commercial settings.
Description
Drybase TS-PLUS Tanking Slurry (20kg) is a cementitious waterproofing and damp-proofing treatment that bonds excellently to masonry and concrete surfaces, providing a durable tanking solution for both internal and external walls. Its vapour-permeable formulation allows the structure to breathe while delivering reliable waterproofing and forming an effective barrier against damp and efflorescent salts. Suitable for above-ground interior and exterior walls as well as lower-ground basement tanking up to 600 mm deep, it offers versatile protection across a wide range of projects. The slurry mixes in just three minutes with water, creating a smooth, workable tanking cement that can be applied with a trowel, brush or fine mortar sprayer. Once cured, the coating is frost- and heat-resistant, making it ideal for harsh weather conditions and dependable for both domestic and commercial applications.Composed of cement, graded quartz sand and selected performance additives, this slurry is designed to resist frost and heat after curing. It forms a tough, efflorescence-free layer with excellent adhesion on both horizontal and vertical surfaces. Once set, the coating is suitable for internal or external use, including damp-proofing walls above ground or waterproofing lower ground structures up to 600 mm below ground level.Drybase TS-PLUS can be applied by brush, trowel or suitable spray equipment. Each coat should be applied at 1–2 mm thickness, with a total build-up of 2–4 mm over two layers. The second coat should be applied while the first is still damp. A 20 kg bag covers between 3.5 and 5 m², depending on surface texture.Substrate preparation is critical. Surfaces must be structurally sound, open-pored and free from debris, laitance or contaminants. Render preparation is advised for porous substrates such as blockwork. Before application, substrates must be damp but not wet, and any active leaks should be plugged using Drybase Waterproof Plug.Once applied, the coating must be protected from frost, high temperatures and direct sun for at least 24 hours. In ponding or aquatic installations, allow 7–14 days curing followed by a full rinse before introducing water. After curing, it is possible to apply vapour-permeable decorative coatings or plaster over the surface, following the appropriate waiting period and guidance for surface keying.
