Application • Waterproofing of landscaping, terrace garden and planters. Advantages • Anti-root. • UV Resistant. • Exhibits good water proofing character. • High Flexibility. Application Methodology • Ensure that structure is sound and free from dirt, soil, oil release agents, laitance and any other foreign materials which may impair the bond, penetration and/ or the overall performance of ShaliCem EWP AR. • Chemically remove any efflorescence, form oil, mould etc. • Repair any cracks, honeycombed pockets or holes by Shalimar Dam-It or PlastiSeal. • Ensure to dampen walls for an hour before application and keep damp allowing moisture to soak in. Wet dense concrete at least twice, not less than 30 minutes apart. Surface must be damp during application. Do not allow standing water. • Prime the area with slurry by mixing one part of ShaliCrete E with two parts of neat cement i.e. in the ratio 1 : 2. • Add Component B into a suitable container containing and thereupon, add Component A slowly whilst mixing thoroughly mix it preferably in a Jiffy Mixer. • Crush any globules formed to make uniform paste and continue mixing. • Apply ShaliCem EWP AR on clean and dampen surface with stiff fibre brush. Scrub well into the damp wall filling all pores and finish with final stroke in one direction. Keep a wet edge. • Apply second coat when the first coat is touch dry. • Allow to dry for 24 hr before moist curing. Do not apply water through a hose or pressurized nozzle.
Description ShaliSeal PU (earlier known as ShaliFlex PU) is single component Polyurethane 1st category elastomeric sealant. ShaliSeal PU resists cracking arising out of movements of joint materials.

Advantages · One component ready to use. · Good adhesion on many substrates. · Good weathering and aging properties · Excellent workability, easy to use. · Can be top coated. Application Methodology · Surface must be clean, dry and free of grease, oil and painting compound. · Concrete surface must be dry and stable (atleast) four weeks. · Check that mastic is compatible with surface in terms of adhesiveness, staining and chemical compatibility (test a section first). · If necessary apply a thin layer of Sealant Primer on the surface. · After the primer has dried press flexible non adhesive filler on to the groove. · The joint filler should be free of holes to ensure that bubbles do not form in the joint. For better finish use protection strip. · For a narrow joint apply the mastic in one movement and for very wide joint, apply the mastic in three places: The first two on the edges of the joint and third in the joint filler. · Smooth out with soapy water. Press the mastic against the edges and the joint while taking care not to create air bubbles. Remove protection strip. Cleaning Maintenance Clean the equipment with solvent like Xylene, Toluene. Polymerized mastic can be scrapped off.
