    If you mix this up with clear lacquer instead you'll have something that will take stain, somewhat, & take a clear finish pretty well. It is, after all, sawdust & has no grain in large patches, but if you use the sanding dust from the project you are filling you can't get a closer match. It also has the benefit of being very easy to store & you can revive it if it's thickened or even dried out by adding a bit of lacquer thinner & more lacquer. I've seen hardwood floor guys do 3 rooms worth of new, unfinished flooring with a 5 gallon bucket 2/3 full to start. Also doesn't cause blotchy spots in the finish like a glue will.

    I do this all the time when working with exotic woods because pin holes can be filled with an exact color match and it takes stains and finishes the same as the rest of the wood. Nice write-up.

    In the UK we call this product plastic wood.

    You can buy it or make it.

    When totally dry you can treat it more or less like real wood - sand drill, paint - If you use very fine sawdust you will get a good finish.

    PVA glue isn't waterproof although Titebond may be depending on the grade.
