![sika-1500x1500](https://www.rhsboating.com.au/images/com_hikashop/upload/sika-1500x1500.jpg) Description: Match the sealant to the marine job with Sika products from RHS Boating & Marine. This collection is for boat owners and maintenance professionals selecting materials for suitable sealing and installation tasks. Whether fitting hardware or replacing a deteriorated seal, the choice should be guided by the surfaces involved and the requirements of the specific assembly. Sika products identified in the supplier catalogue include Sikaflex 291 and selected Sika silicone sealants. These formulations should not be treated as interchangeable. Adhesion, flexibility, preparation and finishing requirements depend on the product, so checking its intended application is an essential part of planning the work. Begin by identifying the substrate, existing coatings and any old sealant that needs to be removed. Review the selected product's preparation instructions, including whether cleaners or primers are required. Consider the joint dimensions, exposure and access for applying and tooling the material. Packaging size and colour also affect the purchase, especially when the finished joint will remain visible. The finishing details of a sealing job are easier to control when preparation has been planned in advance. Consider access for masking, applying the material and removing excess in the way specified by the manufacturer. Allow enough time for the work to proceed without rushing the preparation stage. This is particularly useful where a visible joint forms part of the boat's appearance, or where the fitting will become difficult to reach once surrounding equipment has been reinstalled and the project is complete. Shop Sika at RHS Boating & Marine to build an installation order around the appropriate sealant and preparation materials. Read the technical directions before opening the product, and allow the specified time for curing before putting the assembly into service. A planned approach helps you coordinate preparation, fitting and finishing so the sealant is used as part of a suitable process rather than as a last-minute fix for an unidentified problem.
