Treatment of plaster background. |
| Any normal plaster background such as masonry,
concrete, light-concrete, is suitable. The Plaster background
should be exa- mined and checked in accordance with Knauf's
instructions and recommenda- tions. (See separate leaflet). Clean
the plaster background remov- ing any dirt or loose material.
Remove any rough unevenness. Knauf "Beto- kontakt" must
be applied to smooth concrete surfaces. Pretreat highly absorbant
backgrounds with Knauf "Primer". |

Spreading and leveling
- Spread with h-section feather edge and level plaster.

out any uneven- ness.
Smoothing
- When the plaster surface is dry smooth down with float,
smooth a second time if necessary.

Treatment of surface prior to painting, papering
or tiling. |
|
| The plaster must be dry, firm and dust- free. The
moisture content should not exceed 1 %. Before painting or
wallpapering the surface should be primed with a suit- able primer
e.g. Knauf Solvent Deep Primer. Surfaces to be tiled should be
left rough to provide a key, do not float and smooth. |
|
|
Tiles laid by the thin bed method. Minimum
plaster thickness when tiling 10 mm. |
|
| Prime the entire surface with a synthetic resin
solution (e. g. Knauf Deep Primer). Affix tiles with either, Knauf
Building and Tile Adhesive (a cement-based thin bed mortar), or
Knauf Tile Adhesive (a resin-based dispersion adhesive). Do not
joint until the adhesive is dry. |
