If you are applying thermal liner & KV600 over plaster base, lightly sand then PVA bond 2 times to seal the wall.If you are applying over painted plaster, lightly sand then PVA bond to seal the wall. You can apply over a paper product e.g. lining paper, woodchip embossed papers. Do not apply over vinyl or blown vinyl wallpaper, as this will reduce the breathability of the thermal liner. Again lightly sand then PVA bond the wallpaper. Once this is done let the PVA dry for a minimum 24 hours at normal room temperature no heating windows open if possible. Mark the wall away from the corner approx. 70cm (thermal Liner) 95cm (KV600) and draw a plumb line (straight) to start from. Once this is done open the thermal liner adhesive and stir (if in a bag empty into the tub first). Cut lengths before starting. Apply a good amount of adhesive working away from the corner to the wall enough to hang 1 strip at a time of thermal liner (apply approx.1m wide - KV600 1.3m Wide), This is so there is enough to cover the edges at both sides using a medium pile roller and a brush for the top, bottom and corners. Repeat the above until you get into the opposite corner, cut and trim into the corner do not go around internal corners as they are not usually straight. Once you have done this finish the wall on the opposite side going into the corner when you started from but did not do. Repeat the above for the other walls. Once this is done let dry for 24 hours at normal room temperature - no heating on and windows open if possible. Once dry you may need to lightly fill the joints with flexible filler and before doing this you must paint the joints with the paint you intend to use, DO NOT apply the filler directly on to the surface of the paper because you come to sand down it will damage the surface of the wallrock thermal liner. If painting first, when you sand down you will be sanding onto a painted surface. If wallpapering on top, and if the gaps are very small the wallrock power adhesive will fill them, so if you need to fill there is no need to paint the paper first as you will be covering it with the wallrock Fibreliner, Premium, Fibreliner plus, Armadillo, Wallrock Texture or Wallrock Trend. Tips to hanging
  1. Applying around external corners is ok although you will end up with a rounded corner.
  2. If you want a straight corner you must use the wallrock Fibreliner, Premium, Fibreliner plus, Armadillo, Wallrock Texture or Wallrock Trend to hide the cut as you will see the furry backing of the wallrock Thermal Liner .
  3. Again as above if you are doing round windows, and if you go around you might need to pin the thermal liner in place to stop it springing back just until it is dry.
  4. Light switches and plugs – just screw away and tuck behind (you may need to buy longer screws to secure back) when tightening be careful not to over tighten as this will push into the thermal liner surface.
