How to install hatches and fittings on a boat?

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.

These fittings can be effectively bedded and sealed with only Sikaflex®-291i or if the joint remains visible and is exposed to weathering, then use Sikaflex®-591 or Sikaflex®-295 UV.

Check pre-treatment chart for surface preparation of substrates prior of application and follow application steps according to application guidelines.
