Sikaflex quickie

[Iain C]

OK, I made a mistake a few years ago and used cheapo mastic to seal something on my boat and it's all but fallen out and I need to redo it.

The boat is a Sabre 27, and the hull/deck join has a teak strake all the way along the hull covering that join. I want to seal the gap between the top of the strake and the deck moulding, and the bottom of the wood and the hull moulding. Essentially this equates to 4 Sikaflex "fillets" each 27' long.

Two questions:

1-What is the best grade of white Sikaflex to use?

2-How many tubes do I need?

Thanks!

Remember re-sealing the rubbing strake on my Sabre (Sabreon) in 1995. Cracking boat.

I would suggest around 5 tubes and I would use 291 and a decent gun. If the bead is narrow it is the devil to pump. Better if you warm the tubes first. Freeze any part tubes to keep the stuff fresh.

If Sikaflex is your poison then 291i is the one to use. It is an polyurethane based adhesive sealant.

There are some alternatives. CT1 has an enthusiastic following among forumites. http://www.ct1ltd.com/en/ct1.html

Other suggestions will no doubt follow
