Details on How Much Paint, Wallpaper and Number of Tiles to Use
Floor and wall tiling
The following table shows the number of tiles you will need for each square metre of surface to be covered. You should add 7.5% to these figures and more if the areas are interrupted by projections and the like.
| Size of tile | Number of tiles |
| 100 x 100mm | 100 |
| 150 x 75mm | 89 |
| 150 x 150mm | 44 |
| 200 x 100mm | 33 |
| 200 x 200mm | 25 |
| 225 x 225mm | 20 |
| 250 x 125mm | 32 |
| 250 x 250mm | 16 |
| 300 x 150mm | 22 |
| 300 x 300mm | 11 |
| 450 x 450mm | 5 |
| 600 x 600mm | 3 |
| 600 x 450mm | 4 |
When buying the materials make sure that you can obtain a refund on any unopened packs in case you have over-ordered. If you are fixing ceramic tiling, you will probably need a paste-type adhesive and this is sold in tubs of different sizes to cover between one and six square metres of tiling.
Painting
The covering capacity for paints depends to a large extent on the surface being painted, the type of the paint and the skill of the painter. The figures set out below are based upon brush application for square metres per litre of paint.
| Surface | Undercoat | Gloss | Emulsion |
| Plaster | 11-14 | 11-14 | 12-15 |
| Brickwork | 6-8 | 7-9 | 7-9 |
| Blockwork | 6-8 | 6-8 | 6-8 |
| Woodwork | 10-12 | 10-12 | 12-14 |
Wallpapering
The number of rolls of wallpaper needed to decorate a room will depend upon size of the pattern repeat, the number of doors and windows and the height of the room. The table below gives the number of rolls required for different-sized rooms with a standard number of doors and windows.
