There are several types of ceiling tiles such as cork, wood fibre or polystyrene, which make attractive ceiling finishes.
The ceiling surface should be prepared carefully. It should be smooth, clean and grease free. Where distemper has been used, this should be washed off thoroughly.
Large holes or any cracks should be cut back, dampened and filled with a non-shrink cellulosewhich is allowed to harden before being smoothed down.
Let’s line up
The method of setting out the ceiling area is similar to that of floor tile laying. Unless you are using tiles with flanged edges, when tiling starts at one corner, fixing should start in the centre of the ceiling. Find this centre using a chalked string.
Position the chalk line from the marked points and twang the line to mark the ceiling into four sections. The point of intersection is the centre of the ceiling.
Count the number of the tiles that fit along the lines. As the tiles are unlikely to fit the module exactly, it will be necessary to cut at the outside edges of the room. If the gap is more or less than half a tile width, adjust the centre line so that there is a half-tile border.
Place a group of four tiles round the centre point, with two edges of each tile along the lines. Once these tiles are carefully aligned, further rows of tiling should be lined up accurately. Continue tiling out towards the walls.
Lining a ceiling with polystyreneor tiles provides a decorative surface and gives added insulation. This material, in tile form, is excellent for areas of potentially high condensation such as bathrooms and kitchens, though a wide range of textures and patterns make tiles or veneer an acceptable decorative surface for use in any room in the home.
Stick em up
When fixing polystyrene tiles apply theevenly to the back of the tile and allow it to set slightly.
Wear cotton or woollen gloves when handling polystyrene to minimise the risk of marking the surface. Position each tile and press it firmly but gently into place.
It is unlikely that the tiles or veneer will fit the ceiling area exactly. Therefore some cutting in and trimming will be necessary at the room edges, into corners and around light fittings. Cutting round ceiling edges is done, using a scribing method similar to that for laying floor tiles.
Use a sharp trimming knife or a razor blade to cut polystyrene tiles; cut the tiles on the face side.
If flanged tiles are being used, start tiling at one corner with the flanges facing outwards. It is important to make sure that there is an even border of about 150mm around the room.
First, measure the distance across the ceiling at several points; if the distance includes an odd number of millimetres, add these equally to the border. Use a chalk line to mark the position of the border along the long and short wall.
Place the first corner tile, scribed to fit closely between the chalked marked line and the walls. Cut the tile on the scribed line, using a. The waste side of the cut should be the grooved edge.
Polystyrene veneer, which is supplied in rolls, is fixed in much the same way as any ceiling paper. Great care should be taken to align any pattern and ensure that the lengths are butt-jointed.
Cutting should be on the face side, using a sharp trimming knife, held against a straight edge. Veneer can also be painted to match in with decorative schemes.
Tiles and veneer can be painted with a water-based or emulsion paint. Never use a gloss paint as this could create a potential fire hazard.
