I'd stick it all back down before sanding. Stick it down with epoxy - I used this for my bathing platform:

Sikaflex it first but let it *properly* go off before sanding. This is the sika that I used:

Apologies for jumping in but I've got an issue with one of the steps down to the bathing platform with loose teak and need to re-fix it. The epoxy above appears to only come in bulk quantities, any suggestions on what to use for a small area/quantity?

You should only use epoxy if the teak is less than 6mm thick as greater than this the expansion and contraction forces may overcome the epoxy. Sika do flexible adhesive as well as caulk. You don't need to treat teak. It needs to be clean but rough-ish on the side being stuck down for good adhesion. The deck needs to be clean and sealed. Use weights or screws and a large washer between each board to hold it down. Epoxy any screw holes when you remove them to seal. Then caulk as per Sika's instructions. Sand to remove excess caulk and finish.

Not quite, he has to invite me over to inspect his work in progress and crack open the funbox while we deliberate over the job for an hour or two before he starts. Maybe more. Depends on how deep the funbox is and how long it's going to take him to do the job. Jobs take longer when it's sunny.

I'm free on Saturday Roy :encouragement:

well what do i seal the grp with and surely i have to treat the teak after sanding ,help

 

[BruceK]

Good point. Worthy of a beer or two's deliberation. :encouragement: What do I know about teak? Nothing But I hear some like to oil it but this is frowned upon as a perversion. Teak should be grey. Unless sanded. Then the dust should be red. If it aint red then it's not pukka pukka teak but probably this commercial grown stuff that doesn't have the same amount of natural oils in it. Dilemma. Varnish or oil? Then of course you're done for, because if you varnish this rubbish stuff everyone is gonna call you an anchor for not having grey decks and your social status will be in tatters. As I said. It's worthy of deliberation. Maybe a crate. Hopefully it's sunny. While it's all up we can even discuss this synthetic stuff. It's all the rage. Red decks forever and nobody calls you an anchor, you're positively green. Even the raggies will dip their colours as you steam past. Make that 2 crates :encouragement: Perhaps you should ask the Squaddie next door for advice. Servants entrance only though :encouragement:

You seal the deck as required and depending on what the sub deck is. Generally epoxy is the job for repairs and sealing +/- glass fibre. Teak requires no treatment other than the odd bucket of salt water thrown on it unless you are interested in an aesthetic that is different from natural teak and wish to ruin all the beneficial properties of natural teak.

I have no idea. I use teak for its natural anti slip and durability. I don't understand why anyone would ruin that by adding stuff to it. Why not use a fake teak as you seem to be getting all the drawbacks of wood without any of the benefits with your current plan. Teak has natural oils which resist some products. If you are simply looking for an aesthetic appearance maybe a thin teak deck veneer panel would do and could have epoxy over it. I have never done anything like that. I do varnish some teak trim and it looks good but it would be terribly slippy under foot and would require a lot of maintenance.

 

[BruceK]

Your teak looks great. Why do you want it to look like a suburban fence for? You'll want underwater lights next.

Sikaflex 298 is specifically designed for bonding teak decks. Application instructions here: http://www.bluemoment.com/downloads/sikaflexmarinehandbook.pdf

I used it to bond teak decking panels to my flybridge in 2008 and it's still going strong with no lifting.

Edit: also just noticed that the epoxy Jimmy linked to is available in 500 g containers, so you don't need to buy it in bulk.

So an update so far ,i have got all one side off the starboard side got it home and got oll silkaflex of ,then sanded the top sides of each strip i plan to take it and glue down back on the boat ,also screw it down until it sets then take out all 171 screws then glue in some 10 mm plug and wait till they set ,then caulk up and wait till set then sand and semco up ,this may take a few weeks is it worth taking photos ,and does the way to do it sound right .thanks for any replies .roy

 

[pmagowan]

If using the screws only as temporary clamps then make sure they are filled with something like epoxy where they penetrate the sub deck. Inevitably water will get through the teak so the prime importance is that the sub deck is sealed. You can plug the teak with ordinary plugs and glue for aesthetic reasons. A syringe is good for getting the epoxy into the screw holes.

 

[BruceK]

Just a question Roy. When we go to Caernafon, yeah. Are you going to be carrying all the planking on the flybridge like a roof rack?

Cos you know all them Squaddies and Prinseekers in Vicky Dock gonna look at you like yer the Third World's answer to Dell Boy, yeah?

Agreed - that is a pro way to do it. Just to be clear: epoxy for sticking the planks or sheets down, then black polyurethane for the caulking lines. The epoxy is generally used in vac bag situations but lots of weights will do of course. I happen to prefer TDS440 for the caulking stripes to sika, but no big deal/each to their own

Well i have gone and bought 3m 5200 fc adhesive to hold down will i need to prime with epoxy ,as my probem is when i go for the day i would like to glue alll one side of the teak down ,but if i have to wait for primer to go off will i be able to do it ,and last question will 6 tubes be enough to glue one side of a 35ft boat
