Sikaflex® Pro+ is a 1-component moisture curing polyurethane elastic sealant and adhesive that is formulated on 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 low environmental impact and 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 sealant while curing even in extreme conditions.

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, as a sealant for draught-proofing and general sealing and filling applications.
Pro+ may 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. (surface can be damp but not wet. If uncertain then 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 work clean, apply masking tape to the top edge of 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 sealant has skinned, tool off with an appropriate spatula to give a smooth finish.
Remove the masking tape and clean up immediately.
