To cover the drilled holes on mdf?

Tony.ca · 19th April 2004, 04:38 PM

Hi there,

I need some advice on covering the holes that I had drilled on MDF to hold the enclosure box together after gluing, since i did not have any clamps to clamp them.

I want to get a smooth finish on the box and then want to paint it.

Any suggestions would be appreciated.

Thanx,

Tony

Just use some wood filler. After it dries sand it smooth with 220 grit or finer sand paper and paint it.

I prefer to use the epoxy type wood fillers where you have to
mix two parts. It dries fast and it's a hard finish that is sandable.
The non-epoxy type fillers may crack over time. /hehe

The hardware store should carry this type of product, Bondo
is one brand that offers this.

I have tried a couple of different brand wood filler. No matter what the marketing says on its container my experience with them were they all shrink some what, some more, some less.
Just my 2 cents for consideration..

Regards,
Chris

Ditto here, wood filler don't work so good. I used Bondo last time and next time I may try the epoxy.

I always save some of the mdf sawdust and just mix it with wood glue. Ive been doing this with all types of wood. Just mix dust to glue until its a peanut butter consistancy. you want more dust than glue.

One of the best I have found is to use a combo of the polyester resin (used for fiberglassing) and talc. This is what they use under the fiberglass to fill holes in the plywood before glassing.

Not sure if you'll find better than that.

Used to make my own out of standard 2-comp epoxy glue and appropriate saw dust to match the wood....
This mix can be sanded, planed, knifed- takes just about any tooling. Slightly overfill the hole and use a finely set and very sharp hand planer to level before sanding...
