Frequently Asked Questions
Winches, windlasses are subject to high mechanical stresses, fans, hatches and hatch covers to low stresses. To make sure your fittings are sealed strongly we recommend the following:
Bedding and sealing of fittings subject to high mechanical stresses
Deck fittings such as chain plates, winches and guide rollers must absorb very high dynamic stresses. For this purpose, a high-performance product, Sikaflex®-292i, our assembly adhesive, should be used in conjunction with additional mechanical fixings.
Bedding and sealing of fittings subject to minimal mechanical stresses
Deck fittings, such as ventilators and cover strips, need to be waterproofed but are not subject to high tensile or torsion stresses.
Check pre-treatment chart for surface preparation of substrates prior to application and follow application steps according to application guidelines.
You will find different variations and materials for rub rails such as GRP, paints, wood and moulded PVC, etc. Therefore a good surface preparation is key. Products needed depending on the rub rail material to be bonded.
To ensure a good final result follow the advice given in the pre-treatment chart. Common product for rub rail bonding is our assembly adhesive for marine Sikaflex®-292i or the STP based marine sealant Sikaflex®-591.
