Sikaflex 522 adhesive is recommened for sealing DIY awning rail installation as it gives a stronger bond to the rail and the flexible seal will not shrink or crack over time.

Americans seem to use a sealing strip when regluing the railing; us Brits seem to like to use Sikaflex 522.Suitable substrate materials include timber, glass, metals, metal primers and paint coatings (2-part systems), ceramic materials and plastics. It’s been sat in a barn for 30 years so is dead dry, but has not had any real maintenance during that time. Suitable for the sealing and bonding of various applications internally and externally in caravans and motorhomes, including skylights and aerators.

Sikaflex®-522 is generally resistant to fresh water, seawater, diluted acids and diluted caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils; not resistant to organic acids, glycolic alcohol, concentrated mineral acids and caustic solutions or solvents. This multipurpose adhesive sealant from SikaFlex is ideal for caravan and motorhome construction and repair. I’m so paranoid about water ingress I can see myself using W4 with an edging of one of the above sealants (and on the nails of course! Sika EBT is named for its elastic bonding technology which bonds to brick, mortar, wood, metals, glass, resins and plastics.Use Sikaflex 522 to fit and seal motorhome ladders, roof racks, caravan bike racks, trims and high top roofs as it creates a strong bond and simutaneously seals screw and bolt holes in the vehicle bodywork.

Suggestions for surface preparation may be found on the current edition of the appropriate Sika® Pre-Treatment Chart. Seek manufacturer’s advice and perform tests on original substrates before using Sikaflex®-522 on materials prone to stress cracking. Sikaflex 522 is also suitable for the replacement of joints on both caravan marine and other vehicular construction projects. Surface treatment depends on the specific nature of the substrates and is crucial for a long lasting bond. Sikaflex 512 has now been replaced by 522 - the sealant is exactly the same but just an updated version.Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility. Sikaflex®-522 can be processed between 5 °C and 40 °C (climate and product) but changes in reactivity and application properties have to be considered. It bonds to a wide variety of surfaces and is perfect for those wishing to create permanent elastic seals of high adhesive strength.

If the paint requires a baking process (> 80 °C), best performance is achieved by allowing the sealant to fully cure first. Anyway, here’s my question: I’ve watched a lot of YouTube videos on removing, resealing, and replacing the railing. If painting process takes place after the sealant has built a skin, adhesion could be improved by treating the joint surface with Sika® Aktivator-100 or Sika® Aktivator-205 prior to paint process. I should have had a tube of it by now but sadly Hermes couldn't find Sainsbury's in Paignton so it never arrived. Consider that these suggestions are based on experience and have in any case to be verified by tests on original substrates.This approach seems best, as you can put plenty on, smooth it over with normal tools before it skins plus it remains plastic over time (supposedly) ? Having a high elasticity for impact and vibration means its also suitable for joint sealing and filling. Sikaflex 522 is both an adhesive and sealant making it ideal for caravan, motorhome and trailer repairs as well as DIY fitting of caravan vehicle accessories.
