Recommenda'ons VELOSIT CW 111 is only available for professional applicators. The crystalline waterproofing principle requires several days of water contact to develop its full effect. VELOSIT CW 111 may discolor or show strong efflorescence in water contact. This is normal and caused by the crystalline reacCon. All described product features are determined under controlled laboratory condiCons according to the relevant internaConal standards. Values determined under job site condiCons may deviate from the stated values. Please always use the latest version of this data sheet available from our website www.velosit.de .

1. VELOSIT ® CW 111 Applica'on fields VELOSIT CW 111 is a crystalline waterproofing slurry for concrete substrates. It is very economic and easy to apply. VELOSIT CW 111 becomes part of the concrete and creates a waterproof layer inside the concrete itself. It is especially strong against negaCve side water pressure. Typical applicaCon fields besides others are as follows: • Waterproofing of basements and below grade parking structures • Waterproofing of potable water structures • ProtecCon of dams and spill-ways • Waterproofing of sewage structures • Waterproofing of tunnels and pipelines • Slab waterproofing (dry shake applicaCon) • Waterproofing of elevator pits Proper'es VELOSIT CW 111 is a crystalline waterproofing slurry with unsurpassed strength development. VELOSIT CW 111 cures a lot faster than the current standard products eliminaCng the need for days of water curing and protecCon. VELOSIT CW 111 creates a reacCve layer inside the concrete that allows the structure to self-heal shrinkage cracks under contact with water. VELOSIT CW 111 surpasses the requirements of EN 1504-3 for concrete repair (CR) and can be used according to the principles 3.1 and 3.3 acc. to EN 1504-9. VELOSIT CW 111 can be applied by brush, dry-shake or suitable spray equipment. • Self healing properCes of up to 0.4 mm staCc cracks • Unsurpassed strength development with more than 20 MPa (2900 psi) aVer 24 h and more than 50 MPa (7250 psi) aVer 28 days • Open to foot traffic aVer 4 hours • Extreme adhesive strength (concrete failure) • Shrinkage compensated, no spider-web cracking • Water curing only under hot and dry condiCons required for 4 hours 2319 page of 1 4 VELOSIT ® CW 111 High Strength Crystalline Waterproofing slurry

2. VELOSIT ® CW 111 • Good resistance against aggressive media with a pH range of 3-12 and against soV water with low ion content • Good weathering resistance • Potable water approved • Good sulfate resistance Applica'on 1.) Substrate prepara'on VELOSIT CW 111 can only be used on concrete substrates. a.) Hardened concrete must be prepared with sand blasCng, shot blasCng or ideally high pressure water blasCng (>100 bar/1450 psi) to remove all bond breaking substances. Substrate must be pore open and load bearing. The minimum requirement for adhesive strength is 1 MPa (145 psi) and for the compressive strength 20 MPa (2900 psi). AcCve water leaks must be treated and fully stopped with VELOSIT PC 221. Leaking cracks need to be sealed with a PU injecCon material. Fill all blowholes, honeycombs or other surface defects with VELOSIT RM 211. Before the applicaCon of VELOSIT CW 111, dampen the substrate with clean water to a saturated surface dry (SSD) condiCon. b.) Cold joints can be treated by chiseling out approx. 5 cm (2“) concrete in a U shape around the joint. Fill the opening with VELOSIT RM 211 and finish with VELOSIT CW 111. c.) Fresh concrete can be treated with VELOSIT CW 111 in a dry-shake applicaCon. The concrete must have sufficiently sCffened that a helicopter trowel can work on it. Do not use any curing compounds or other bond breaking materials before applying VELOSIT CW 111. 2.) Processing a.) Brush applicaCon: Mix VELOSIT CW 111 with 22– 23 % potable water, i.e. 5.50 – 5.75 l (1.45 – 1.5 gal.) water per 25 kg (55 lb.) bag. Fill the complete mixing water into a suitable bucket and mix the powder with a slow speed drill (300 – 600 rpm) into the water unCl a lump-free mix with a consistency of an oil paint is achieved. With hard water (high Calcium content) a slight false seing within the first 2 min. aVer mixing is possible. In such case, re-mix for another 30 seconds. Do not add water! The product is workable for 30 – 45 min. at 23 °C. Apply the first coat with a masons brush in crossing applicaCons to the pre-dampened substrate at the specified rate. The second coat must be applied within the recoat Cme, which is 60 – 90 min. at 23 °C. If too much Cme elapses aVer applicaCon of the first coat, a reduced bond between the layers may be the result. b.) Spray applicaCon: Use suitable spray machines such as: - Inotec GmbH: INOMAT-M8 - HighTech GmbH: HighPump Small - Desoi GmbH: Desoi SP-Y Prepare the product as described for the brush applicaCon under a.). The water addiCon may be reduced slightly to get a more thixotropic mix. Fill the product into the feed hopper of the spray machine and spray conCnuously. If less water is used the whole specified amount of VELOSIT CW 111 may be applied in one liV. Otherwise spray in two layers with a wait Cme of approx. 30 min. between coats.

3. VELOSIT ® CW 111 interrupCons may result in clogging of the spray hose. The product may cure a lot faster if the hose is exposed to direct sunlight. Always empty and flush the machine aVer spraying or before long spray interrupCons. VELOSIT CW 111 is a fast curing material and may be hard to remove if leV in the machine. c.) Dry-shake applicaCon: VELOSIT CW 111 can be applied in powder form onto fresh concrete before finishing the surface. The product is applied uniformly onto the concrete and then finished with a helicopter trowel. Make sure that the trowel forces sufficient moisture to the surface to completely wet and embed the powdered VELOSIT CW 111. 3.) Curing VELOSIT CW 111 does not require long term curing as it reacts relaCvely fast with water. Only under hot weather or very dry condiCons water curing for 3 – 4 hours is required. Please consider for the dry shake applicaCon that the concrete may require curing. Take the required steps by either water curing as specified or applying a curing compound.
