Scraping deck free of glue

[Metabarca]

Morning all. I've bitten the bullet and removed the old teak deck that was warped and worn out and I now have to remove the glue that fixed it to the grip deck beneath. The glue is a pinkish substance by 3M and slightly rubbery, so sandpaper is no use. Any ideas as to tools or techniques to scrape it off?

If acetone fails, a big eff-off belt sander and plenty of sand belts.

In my experience of belt-sanders and "slightly rubbery" glue, the glue quickly covers over the grit on the belt and the heat quickly bonds it to the belt . I spent a lot of time with an old chisel trying to scrape the glue from the belt. Otherwise I'd have gone through a lot of belts and I was only doing a square metre or so.

How about a scraper with a tungsten carbide blade, like this one.

I recently used one for scraping anti-foul from the hull. It stayed very sharp for along time. I rounded over the edges and because you pull it along it didn't gouge into the hull at all.

3M makes matching glue cleaners for some of their glue products that let you wipe the old glue right off. If you can identify the right one, it'll save you so much hassle and sanding it's definitely worth trying a few and seeing if any work for your pinkish glue and then buying a box full of it. This is the remover for their scotch-weld products (which are yellowish when dry): https://solutions.3m.com/wps/portal...nder-Cleaner-AC68?N=5006189+3294255188&rt=rud

Great ideas, thanks!

A power planer will allow you to skim all the adhesive off down to just above deck level.
I've used it very successfully to get rid of track mark and its adhesive, leaving a smooth surface without touching the gel coat

Cellulose thinners & metal scourer worked for me

If you have not yet tried sanding, always do. In my experience not all rubbery types of adhesive melt and if they do not they generally keep the belt very clean.

Another option is to use a multitool like fein or simmilar with a scraper blade. Knock offs are cheap now and usually come with a scraper blade.

And also the mentioned carbide blades are often useful.

I've used 'face off' discs successfully. They fit on an angle grinder and are like a really tough version of a green Scotch pad.

Hot air gun and scraper, on a stick if it helps

3M make flaper wheels that remove sealant and glues perfectly with little or no damage to the surface underneath.
Mainly used in the Aerospace industry. they can be fitted to Dremel type equipment.
