1. VELOSIT ® PC 222 Applica'on fields VELOSIT PC 222 is a flash se2ng cement for concrete and masonry. The product is used to waterproof water leakages and as an accelerator for other VELOSIT mortars. It is especially strong against negaCve side water pressure. Typical applicaCon fields besides others are as follows: • Waterproofing of punctual water leakages for example in concrete pipes, water tanks and basement walls • Set accelerator for VELOSIT repair mortars Proper'es VELOSIT PC 222 is a shrinkage compensated plug cement with very fast strength development. VELOSIT PC 222 sets within 10 – 15 seconds. VELOSIT PC 222 is immediately waterproof and anchors itself into the concrete surface. VELOSIT PC 222 surpasses the requirements of EN 1504-3 class R2 for concrete repair (CR) and can be used according to the principles 3.1 and 3.3 acc. to EN 1504-9. VELOSIT PC 222 can be applied by hand or trowel. • Minimal shrinkage/expansion under dry resp. wet curing condiCons • Fast strength development with 12 MPa compressive strength a[er 1 hours and final strength of more than 40 MPa (5800 psi) a[er 28 days • Resists 130 m (400 [.) water pressure acc. to EN 12390-8 • Flash se2ng with water • Ready to receive top coat a[er 10 min. • Ready for water pressure a[er a few minutes • Very good adhesion to concrete and masonry • No cracking • No curing required • Good resistance against aggressive media with a pH range of 3-12 and against so[ water with low ion content • Good weathering resistance • Potable water approved • Good sulfate resistance 2319 Page of 1 3 VELOSIT ® PC 222 Plug Cement And Starter

2. VELOSIT ® PC 222 Applica'on 1.) Substrate prepara'on VELOSIT PC 222 is designed for mineralic substrates like concrete, masonry or absorpCve natural stones. Chisel defecCve area or water leakage open achieving a U-shaped profile. Remove all dust and debris from areas to be treated. Dampen the surface with water to a saturated surface dry (SSD) condiCon before applicaCon of VELOSIT PC 222. 2.) Processing VELOSIT PC 222 is applied as a dry powder into the leakage. Due to the immediate set it is not possible to mix the product with water. a.) Plugging of water leakages: Apply a handful of dry VELOSIT PC 222 (wear protecCve gloves!) into the prepared leakage. Hold for 1 to 2 minutes unCl the product has sufficiently hardened. Immediately shave the surface flush with the substrate. A[er a short waiCng Cme the area waterproofing with VELOSIT WP 101 or CW 111 can be applied. b.) Use as accelerator: VELOSIT PC 222 acts as an accelerator for many cemenCCous mortars. Required amount must be determined in trial mixes. 3.) Curing VELOSIT PC 222 does not require curing. Cleaning VELOSIT PC 222 can be removed in the fresh state with water. Once it has cured acidic cleaners like muriaCc acid are required. Quality features Color: gray Density: 1.2 kg/l Substrate temperature: 5 – 35 °C (40 – 95 °F) Water impermeability acc.
