Fixing Wood Panels with Wood Adhesive
Another way of fixing wood panels is with contact. This can be applied to any sound and level surface-though irregularities up to 6mm can be accepted.
Make sure that walls are clean and dry. Gloss or emulsion-painted surfaces should be firm and free from flaking. Prepared walls should be stripped back to the bare plaster.
Apply theto both the wall surface and the back of each panel with a knotched spreader and allow to dry. When the two surfaces are brought together they will instantly bond.
Therefore, take great care to position the panels accurately, as with most contact, the panel cannot subsequently be moved once the two surfaces have made contact.
An alternative method is to bond panels directly to a wall surface using a specially formulated, gap-filling, containing synthetic rubber, called Gun-O-Prene.
This is applied with a special gun, available on loan.
The adhesive is in cartridge form; applied at the correct temperature, one covers a single standard panel. Walls must be clean and dry and stripped back.
Once the panels have been cut and arranged in order of fixing, apply the adhesive to the back of the first panel, using a steady pumping pressure on the trigger mechanism, to ensure an even extrusion of adhesive.
Draw the nozzle in a line round the outside of the panel, about 50mm in from the edge and across the width, at 460mm centres.
Next, offer the panel to the wall, check for position and press firmly into place, using hand pressure. If the wall surface is slightly uneven, the adhesive will take up gaps. Where there is no skirting board and the panel is entirely un-supported, it may be necessary to pin the panel temporarily until adhesion has taken place.
Warped panels may be fixed using this adhesive. The adhesive is applied to the panel as for a normal fixing, the panel is offered to the wall, pressed firmly into place then removed. Enough adhesive to produce a honeycombed effect will be left on the wall. Leave for 10 minutes, then reposition the panel to make the final bond.
Battens can also be fixed with adhesive. It is applied to the wall surface at 400mm centres and used in conjunction with masonry-nail fixing at high spots.
These can be mitred along the abutting edges with a plane so that they fit snugly together, but this has to be done very accurately. It is easier-and produces a successful corner-to butt the external edges of panels against a vertical strip of timber fixed at the angle.
First, batten up to the corners, so that one vertical batten overlaps the other, presenting a solid timber edge. Select the timber edge strip, which should be about 50mm wide by 6mm thick, and either match the panelling or be of a contrast wood finish, and pin this on the face edge of the angle. Punch down the heads of the pins and fill the holes.
The two panel edges can then be butted neatly against the edge strip and pinned.
No special treatment is involved. Place two adjacent vertical battens alongside, butt the two panels at right angles together and pin.
