mdf: smooth or rough side for glueing?

tuanj's picture

I'm cementing some formica to my 3/4 mdf countertop. Does it matter any which side of the mdf gets glued-the smooth or rough? Thanks.

I've never seen mdf with two different sides.  Both are smooth.

I've also never used mdf as a sub strait.

I've always used MDF except once a few months back. I used plywood for a counter top for an RV and it didn't stay bonded! Ate the job. I've never had MDF not bond so go figure.

Maybe the ply sucked out the adhesive too much.  For example, on all industrial flake substrate counters, I'd double coat all raw edges for that reason.  And that was with the killer fume glue.  After switching to water based, I poured and "troweled" the adhesive along with dbl brushing the edge.

 

*couldnt figure how to spell sqee-g.

 

think I only used ply a couple times.

 

Did a million feet of laminate in some mall work and there was a lengthy discussion about the total amount of flammable substrate...... The particleboard........exposed on the open bottom counters.  Been too long to remember what we had to do.    Enjoyed the education working commercial.
