January 26, 20242 yr Can expanding foam be used to fill and stick MDF panels to uneven plastered walls? I resorted to zig zagging adhesive but not convinced! I tried it today but the foam just 'rolled' off....the panels are 600 x 1200. What's the best technique to stick them? Thanks!
January 26, 20242 yr I bought some of this https://www.toolden.co.uk/sealants-adhesives/adhesives/grab/illbruck-pu700-multi-purpose-construction-adhesive/?gad_source=1 seems pretty solid. used it to stick timber to my screed that has ufh pipes in it as I didn't want to screw into the screed. can't you use fixings though? would be rock solid with mechanical fixings
January 28, 20242 yr Some MDF has a release agent built in, why it is not used to reinforce composite plastic parts.

This is because one end of the molecule hydrophobic (non polar), this rejects water (polar), and other materials that have the same electrical charge.
