I have an MDF wasteboard about a year old, resurfaced twice. When I use double sided tape it often pulls up chunks of the MDF. The MDF didn’t do this when it was new. I have had parts fail because the MDF is pulling loose before the tape is.
Has anyone found a solution to this?
I have thought of coating the top with a
sealer but did not want drips in the dog holes.
I sealed mine, but I’ve converted to the masking tape and glue method which is working great for me.
Brush on some shellac. Dries fast, won’t cause it to swell, and stops the fuzzies that double sided tape both cause and fail from.
Same thing for me when I was using carpet tape. Agreed that masking + CA glue won’t do that.
Thanks All,
I was moving away from the masking + CA glue because of the fumes. The fuzzies were causing that to fail as well. I will break out the shellac and report back.
I have had issues with cheaper/poorer quality MDF.
I use Medite MDF not the cheapest but by far the best.
sand to 360ish brush off and coat of sanding sealer. leave that to dry for a good few hours.
I then use Painters Tape, CA Glue and Activator
To remove parts I use a very thin decorators scraper, if any tape is left or the spoil board starts to look uneven i lightly rub over with some 400G on a flat block of hard wood.
Habits from a machining apprenticeship 30+ years ago where we used to gently stone a machine tape before bolting parts or fixtures to it must have conditioned me lol
