Any recommendations? Just bought the best that B&Q had, not used it yet but doesn't look any better than the last one.

There must be a Rolls Royce gun out there?

B&Q trade point or Screwfix used to do an "ever build" branded one, dunno if they still do, but as good as you'll get.

Don't waste your money on sikaflex Andy. Go to Toolstation in the industrial estate up by Raymarine and buy some Stixall. Same stuff as sikaflex but less than half price.

Brilliant. That's one I'm going to log for future use.

Jeff...

Do you think the marine seal is as good or better than sikkaflex?

Been quite dissapointed with the results of the last few tubes of sikkaflex I've used recently.

Admittedly, the surfaces were unavoidably damp when the stuff was put on, but you mention this stuff was put on underwater!?

Good price too!

Throw all your manual mastic guns away. You need to be mastic yoda to get a nice even finish.

18V Cordless Caulking Gun | Power Tools | Ryobi Tools

We got these in work years ago. I was the biggest skeptic but I'm happily converted now. lets you concentrate on your aim and gives a lovely smooth bead.

We also use a spray bottle with water or swarfega Jizer/water mix if you want to smooth it out. Takes a little bit of practice but it means you can manipulate the finish you want without the stuff sticking to your blue glove.

hi steve

certantly as good as sika, i use sikaflex as well but tube life seems to be short with sika for some reason soon as the air gets to it.
marine flex in my opinion does a good job had it on my shock seats with no dramas at all for 3 years stuck an anchor bucket down with it on top of flowcoat never moved.
we do underwater painting at work some times and needed a compound to fill in crevices to prevent crevis corrosion hence i trialed it and did some tests basic prep applied by mastic gun left to cure and not a bad pull off pressure.
theres also a mastic called swellseal also applied underwater and as it says swells on cure 350% not used it on a boat [ideal for sealing transom bolts etc] but have used it to seal steel plates on penstock gates where it meets the brickwork to make the seal.
as a tip for storing we use to use aquasure for mending dry suits which we kept in the fridge to give long life just take out 24 hours before use to bring to room temp might work with sika once opened.
hope that helps.

cheers

Jeff,

Thanks for tip on swellseal. We've been attempting to seal deck leaks around bolts and a plate with sikaflex to limited success.

Guys, DIY silicone, decorators caulk and sikaflex tip... Baby wipes! It will change your lives.

Nice neat finish.
