Exterior wood filler

[Cornishkiwi]

Hi all

Just wondering if there is any brand recommended to use as a filler on a teak deck? I'm sceptical to use any old filler as its durability I'm after due to it being outside on the deck. The planks are in good enough condition to not replace however there are a few with little cracks or chips which I need to repair.

Any recommendations would be much appreciated

Thanks

Since you are only trying to fill little dings, a black silicone sealant comes to mind. In evaluating choices (among many) pay attention to the "years" rating. It is a rough measure of the amount of water in the mix, with cheap no-claim silicones having more water in them, ergo they shrink and crack. The black silicone used to mount my ports has not budged in several years, and is quite stiff.

My issue with that is where theres chips it may look wierd with a bit of black silicon in the middle, I feel.i can get away on the sides due to blending it in with the seams. At minute I'm leaning to making an epoxy paste with a lighter iroko, my only concern is epoxy UV resistance

Problem with epoxy is that it has an expansion rate different from wood as the wood expands and contracts with heat and moisture.

Bedding compound for wood needs to be flexible and adhere very well to the wood. Don't need to reinvent the wheel here, look up bedding compounds for wood suitable for a marine environment, there is a big variety.

By the way, you can purchase epoxy with a U/V filter, but its effectiveness against the sun is still limited. It is more of a reddish color.

You can carve wedge shaped "slivers" from a scrap of teak. Mask around the cracks on deck then tap them in with a little glue. The glue will darken the wood so don't use much. You can use Gorilla glue for this or Titebond 3. Epoxy will also be fine. If you use Titebond you don't have to wait for the glue to dry. Level it off with some sandpaper or a sharp chisel then peel the tape

Do not use any silicone based product. I would as mentioned above use the same compound you plan to use for the joints (assuming an STP sealant like sika 591 or likewise?) also as mentioned the ‘proper’ way is to it in new pieces and glue. The black stp actually looks pretty good when it’s done.
