Hd plaster patch7/23/2023 ![]() It will last longer than the wood! One question – what is the best filler to use over an exterior oil primer like Zinnser Cover Stain or water based 123 on exterior trim? I’m still refinishing some trim and after priming there’s always a few imperfections I missed before applying primer. Don’t ever have to worry about that with epoxy. There are many water based grain filler that are fine for interior use, but I could find little info on how they would stand up for exterior use. With the System Three paste I was able to apply a very thin smooth coat of just enough epoxy to fill the grain and required minimal sanding afterward. The West System with filler would have probably worked as well with but would have required more sanding. Finally I will say that System Three is similar to Abatron with a liquid and putty but adds a paste epoxy that is the bomb in certain situations. If you are doing a lot of work it’s economical by the gallon compared to Abatron. Multiple hardeners, can be turned into a paste with wood flour / dust / synthetic fillers. I really like the versatility West Systems liquid epoxy resin. They seem to be ver similar products in short time use – but guess you would have to do a long term exposure test to say for sure. Would be good to know how the newer DAP Platinum Patch compares to MH Ready Patch. If you’re on a budget this might be the answer, otherwise I would prefer WoodEpox for large repairs over Water Putty. I have moved away from it in the recent past because while it is considerably cheaper than Abatron WoodEpox I have found that it’s rock hard characteristics make large patches wiggle free of the wood over time thanks to expansion and contraction. Unlike other wood fillers that shrink as they dry Durham’s Water Putty expands to fill the hole. ![]() Water Putty can work both outdoors and indoors, but without priming and paint, it will mildew and fail rather quickly outside. Drying time varies wildly depending on how big the wood patch is and the weather. Once it is dry, sand it smooth, prime, and paint. If you need it to stick to a vertical surface, mix it thicker.Īpply it with a putty knife or whatever tool is most applicable to your project, and let it dry. If you want it to self-level, mix it thinner. Mix the powder with water to whatever consistency you need. This product is extremely popular and it used to be a mainstay of my shop early on. You can also read the results of my 5-year field testing of most of these wood fillers and epoxies at The Wood Filler & Epoxy Test (Year 5) to see how these products performed in the real world as well as to watch the video below.
