Removing Deck Caulking
« on: February 14 2020, 17:32 »
Does anyone have experience of removing the teak deck caulking with a multi-tool.  I was looking at "J" section blades but cant decide on which blade width to buy.

Also, I'm thinking of replacing the caulking with CT1.  The CT1 demos on Youtube look promising and its relatively cheap and easy to get hold of in large quantities, plus it doesnt seem to "go off" quickly in the tube.  Again, any experiences of CT1 as a caulking on the forum.

Many Thanks.

CT1 is not suitable for caulking - it is a modified polymer adhesive sealant. The correct products to use are those specifically designed for the job such as Sikaflex 290 or TDS SIS 440. Although these are typically twice the price of CT1 it is worth it as you only want to do this horrible job once! Either product is freely available from chandlers.

You will want a product designed for the job, and you should steer well clear of PU based products (Sika) as they don't last too well in the sun. TDS-SIS 440 is the proven goop for the job. Slightly cheaper alternatives are also available, depending on where you are, for example here in Italy you can get Fratelli Zucchini MS Deck Caulking.

I used a thin, sharp knife to detach the old caulking from the sides of the groove and then a sharpened screwdriver of the right width to chisel out the bottom.

Our teak deck is going to come off in a year or two though, as it has annoyed me enough and will be replaced with something more practical that is gentler on the knees >:(

no experience of using CT1 for chaulking... I do love CT1 of certain jobs....just don't ever use it on something you might want to get apart or remove in the future.

I’ve removed the caulking using https://fein.com/en_us/multi-tools/accessories/cutting-scraping/cutter-blade-order-no-6-39-03-200-21-0/ in a multi tool.  Use a slow speed setting on the tool, otherwise it’s a boring but comparatively easy job.

I am off to Greece early much to do the caulking on my Bav39. Fein Multitalent and caulking blade 4mm on its way out there now. I hope thats the right size for mine. I plan on using TDS SIS440. Some of seams abutting the coach roof are only 2mm - poorly laid teak tecks!! but the rest are 4 or 5mm I think.
