I believe this will work fine. I can’t really comment on the strength but this stuff is quite solid so depending on how much weight/pressure you need to have on the hole it should be good for most scenarios. It is basically Bondo and dries very quickly. I would say it will be totally dry to work with and redrill in an hour.
Hello Charles, The question is more suited to the manufacture. You can contact them directly. Generally filler is used to fill not as a sealer over especially over a silicone base. Why would you not simply level off the silicone and paint it to match?
As a furniture maker with more than 35 years of experience, is a must to create some surface with enough grip to attach it. I'm light hand sanding the area with 80 or 100 grit sandpaper. In that way the filler has an increased surface where to adhere
It is, and you mix it in the same way that the one for cars.
Yes. I use this on a wood post on my front porch that was rotting and deteriorated. After conditioning the word with the coordinating Bondo conditioner and restorer, I then used this product to fill in the void. I then screwed the mount for my flag directly into the Bondo and it’s holding up perfectly.
If its to cold takes a long time to get hard, and if to hot it will get hard real fast
If this doesn't work for you, re-drill the hole and use the hardest JB Weld available in the store. That will definitely hold up to a lag screw. Be sure to look up the drill size needed for the size lag that you are using because too small and you will have trouble putting the lag in.
Yes. Light sand prior. Mix a little at a time
Acetone is good start. Should sand area to be patched. No oil or stain in between.
