Can I apply stainable wood filler with a caulk gun?

by Rjack

I just laid plywood in an 18' x 16' room.I am staining but need to fill in gaps with wood filler.Using a putty knife & a can type product is messy, wasteful, & very time consuming.I thought using a pastry bag would be easier than a tub.Any suggestions?

    You will need to add the stain to the wood filler before or purchase filler that matches the finish you are wanting to achieve. To my knowledge, none of it is stainable after drying.

    as re: the pastry bag concept, there’s powdered wood filler that you mix up in batches. You could pre-stain it, or stain it afterwards.

    Idk how long a pastry bag would hold up. How’s about a spritz cookie press, but then you have to wash it.

    If you like the caulk tube idea, premix your filler with, stains, or how ever you wood like 1st. Test a small bit of the filler let dry on a scrap of plywood to see if you like.

    Go to a Good paint store or call call them and all hardware stores to find out if they sell empty caulk tubes, I have done this to make several Different applications,

    and the tubes that I get are only $1.00 so most of the time I keep 2-3 for just cause uses. Good Luck on the Project. Tr.

    thanks. I had to get this project moving so just did it the old fashion on the knees using DAP wood filler (I've used many times) & a plastic scrapper (some plastic is more flexible than the metal ones).

    This is stainable.
