Sikaflex? Pro+ – Solvent-Free, Highly Flexible Sealant & Adhesive All new solvent-free, highly flexible, primer-less sealant and adhesive is the one-stop product for any tradesman and handyman’s home building or renovation. Sikaflex? Pro+ is a 1-component moisture curing polyurethane elastic sealant and adhesive that is formulated with Sika’s newly engineered i-Cure technology to provide higher performance, more movement capability, and improved bubble-free curing. Sika’s new i-Cure technology is user and eco-friendly, with no solvents and a low environmental impact, while maintaining the performance of traditional polyurethane. It is suitable for overpainting with traditional paint coatings. The i-Cure? technology has an early initial set and overcomes bubbling in the sealant while curing, even in extreme conditions. Sikaflex? Pro+ is a high-performance, interior and exterior elastic joint sealant with excellent water, weather, and ageing resistance. It has many uses, including: Expansion joints in walls and cladding Sealing around doors and window frames Sealing penetrations in walls and floors for pipes Sealing joints in concrete and masonry elements Sealant for draught-proofing and general sealing and filling applications Pro+ can be used on a multitude of applications and common building substrates. It has good adhesion to damp substrates. To name a few, Pro+ can be used on: Aluminium Steel Powder-coated metals or glazed tiles Concrete, aerated concrete, cement-based renders, mortars, and bricks Application of Sikaflex? Pro+ Ensure all surfaces are structurally sound, clean, dry, and free from any grease, etc. (The surface can be damp but not wet. If uncertain, apply masking tape to test adhesion. If masking tape sticks to the surface, it’s OK to proceed.) Movement joints must have a minimum width and depth of 5mm. Apply a bond-breaker tape, or backing rod to the base of the joint to prevent 3-sided adhesion. To keep the work clean, apply masking tape to the top edge of the joint on each face. Cut the nozzle to the required width and gun sealant into the joint. Avoid voids or air entrapment in the joint when applying. Before the sealant has skinned, tool off with an appropriate spatula to give a smooth finish. Remove the masking tape and clean up immediately.
