One Component Membrane Forming Waterproofing by CrystallizationProduct Properties • Imparts impermeability to water and dampness to coated surfaces • Gives surfaces that are efflorescence-free, moss-resistant and resistant to fungus growth • Maintains the breathing properties of concrete • Due to excellent adhesion and thixotropic properties, vertical and inclined surfaces can be easily coated One Component Membrane Forming Waterproofing by Crystallization p pp , y • Possesses high flexural and tensile strengths and provides for thermal movements • Is free of chlorides, water-soluble halogens and corrosive substances • Is resistant to alkalis and UV-rays. It is also non-toxic and non-combustible • System protects cementitious substrates against freeze-thaw cycles Areas of Application • Outstanding waterproof and damp proof coat for concrete structures, brick and masonry works, cement renders, plasters etc. • U de g ou d s a ts a d ga ages, eta g a s, tu e s, ate ta s, oo s abs, se e s a d base e ts etc nderground shafts and garages, retaining walls, tunnels, water tanks, roof slabs, sewers and basements etc. • Resurfacing of bathrooms, cellar walls and floors exposed to dampness and attacks from moss and fungus • Foundation walls and footings subjected to ground moisture, water and salt efflorescence can be well protected with coating of Dichtament DS2 Application Notes General Dichtament DS2 is a one component liquid applied membrane is recommended, when Dichtament DS2 is directly subjected to water pressure. In case of sandwiched system the thickness of Dichtament DS2 is a one component liquid applied membrane Dichtament DS2 can be between 1 to 2 mm depending upon forming waterproofing system for concrete, brick, masonry or cement-bound surfaces. The product can also be supplied as a two-component product Dichtament DS and Nafufill BB2. The base component of Dichtament DS2 is a hydraulically setting pulverised material modified with a polymer component, which produces outstanding waterproof surfaces. DichtamentDS2 waterproofing system works on the principle of waterproofing by crystallization and forms an integral part of cement substrates. The crystalline penetration takes place by osmosis and the Dichtament DS2 can be between 1 to 2 mm depending upon actual site conditions. However, the maximum thickness should not exceed 6 mm. Subsequent coats may be applied when the previous coat is not completely dried out, subject to minimum of 1 hour. Care should be taken to protect the coating from being damaged during subsequent operations. Curing and Protection The crystalline penetration takes place by osmosis and the The coating of Dichtament DS2 must be cured by clean water to treatment penetrates concrete even against hydrostatic pressure. Surface Preparation Damp and loose plaster, if any must be removed. All joints must be sound and properly filled. In case of any cracks they should be sealed. Please refer to our technical literature on Crack Injections. The surface to be treated must be structurally sound. It t b l f f ll l ti l il The coating of Dichtament DS2 must be cured by clean water to avoid rapid hardening. Protect from direct sunlight and extreme temperatures. Protective or decorative systems like tiles, wood panels etc. may only be applied when Dichtament DS2 has sufficiently hardened, at least after 7 days. Coverage The consumption (coverage) largely depends upon the It must be clean, free of all loose particles, oil, grease, li ti th d diti it t t t d l efflorescence, traces of form oil curing compounds and any other previous treatments or contamination. Mixing and Application Mixing ratio for Dichtament DS2 is 100 p.b.w. Powder to 26-30 p.b.w. water, i.e. 6 to 6.5 kg water is needed (as per consistency) per 30kg sack of Dichtament DS2.
