Why do I get cracks where my trim (skirting boards, window frames, door frames, Architraves, etc.) meets my walls?
Again, settling and substrate movement cause this cracking and separation between a wall and the attached trim. As discussed earlier, using an enamel based paint will also show these cracks as this movement takes place and the coating breaks. Application of a generous bead of a flexible, acrylic caulk in the void between the wall and trim board before painting will allow for some of this movement to be absorbed. Also, by using acrylic coatings on this area, more flexibility will be allowed as settling and shifting occurs.
