Mould growth on walls and ceilings must be treated first in accordance with MGC Specification. |
| |
|
| 2. |
Surface preparation – existing wallpaper must be removed, artex ceilings should be sanded to remove all high peaks. Fill all large cracks and holes with proprietary filler. Remove all flaking paint, gloss painted walls to be lightly abraded and washed with sugar soap then rinsed clean. All highly porous surfaces, chalking substrates and artex ceilings to be primed with one coat of SEMPATAP ‘A’ PRIMER and allowed to dry. |

| 3. |
Cut SEMPATAP THERMAL to length allowing 25mm overlap at each end. |
| |
|
| 4. |
Roll up cut length of SEMPATAP THERMAL with foam facing out. |
| |
|
| 5. |
Apply SEMPATAP ADHESIVE with serrated SEMPATAP ADHESIVE SPREADER, or suitable notched trowel to wall/ceiling surface. Only apply adhesive to one drop length area at a time. |
| |
|
| 6. |
Hold the rolled-up piece of SEMPATAP THERMAL in one hand and unroll the first half metre, (keep remainder rolled-up), and apply foam side to the wet adhesive. Keep the roll on the wet adhesive. Unroll another half metre. Using light hand pressure, smooth out the unrolled piece that is in contact with the adhesive. If light pressure is used, SEMPATAP THERMAL can at this point be repositioned by sliding into place. |
| |
|
| 7. |
When SEMPATAP THERMAL is in the required position, apply firm hand pressure, or use a rubber roller, the handle of a paper hanging brush or the blade of SEMPATAP SPATULA over the first metre. The remainder can then be unrolled down the wet adhesive and smoothed out. Once applied, ‘firm-up’ with the same tool. |
| |
|
| 8. |
When applying subsequent lengths, apply the adhesive to the open edge (butter) of the previously applied drop of SEMPATAP THERMAL. Bring the drops together leaving a narrow gap of 1-2mm and knife off excessive adhesive. Do not completely butt the edges as this will squeeze out all of the adhesive and not afford a good bond between lengths. |
| |
|
| 9. |
SKIRTINGS, ELECTRICAL FITTINGS (SOCKETS, LIGHT SWITCHES ETC.)
Butt joint SEMPATAP THERMAL or utilise decorative beading where necessary to provide a protective edge. SEMPATAP THERMAL CHANNEL can be used for a neat finish where skirtings are less than 10mm on the top edge or have a bevelled/chamfered design. Before SEMPATAP ADHESIVE is applied, fit SEMPATAP THERMAL CHANNEL to the wall above the skirting using No Nails sealant or similar. Alternatively, remove items and refit over SEMPATAP THERMAL. |
| |
|
| 10. |
Continue the application of SEMPATAP THERMAL by applying subsequent lengths as above ensuring that the SEMPATAP ADHESIVE is applied to the vertical butt join edge of the SEMPATAP THERMAL. |
| |
|
| 11. |
All open joints and seams, both vertical and horizontal, and joints between lengths where the adhesive has dropped back slightly on drying, fill with SEMPATAP SEALANT. When the seam has been filled, wipe off any excess sealant using a damp, clean cloth. Fill any sealant shrinkage with proprietary fine surface filler using a plastic spatula. Wipe any excess from the wall covering using a damp, clean cloth. |
| |
|
| 12. |
EXTERNAL ANGLES, WINDOW REVEALS, SOFFITS ETC:
Cut SEMPATAP EDGING TAPE to required length, fold along the plastic crease line to form a right angle. The plastic should be facing inside. When applied, only the paper side is seen. Brush SEMPATAP ADHESIVE along the plastic and the paper, set to one side and leave to soak for a couple of minutes. Locate over the corner of the SEMPATAP THERMAL and smooth out. Remove excess adhesive and leave to dry. SEMPATAP EDGING TAPE can be ‘feathered out’ using SEMPATAP SURFACE FILLER or proprietary filler. |

DECORATIVE FINISH
EMULSION - Apply 2 coats of BIOCHECK Matt or Silk Emulsion by brush or roller at a coverage of approximately 12 square metres per litre per coat. The first coat may be diluted with 10% clean water. It is recommended that Silk is used in kitchens and bathrooms.
WALLPAPER FINISH - SEMPATAP THERMAL is suitable for all types of wall covering.
TILED AREAS - SEMPATAP THERMAL is suitable for tiling to sinks and baths.
