Finish on Wallrock Thermal Liner
One of the most often asked questions when it comes to Wallrock Thermal Liner is ‘what else do I need to put on top of it’? This question relates to what the type of surface finish you’ll get at the end of the process. There are a number of options and we’ll explore them in this post.
1. Paint it
Wallrock Thermal Liner has a smooth side, which is ready to be painted. So, if you have achieved flat surface with Wallrock Thermal Liner and you are satisfied with it you can paint it. Once you have put Wallrock Thermal Liner up on the wall you do need to leave it for at least 24 hrs to dry before painting.
2. Use Wallrock wallcoverings
Why would you use anything else on top of the Thermal Liner if you can paint it? As Wallrock Thermal Liner is 3.2 mm thick and if your wall isn’t perfectly flat you might get step-like differences between each drop. Most likely it will be tiny, but to a lot of people that’s not acceptable and they would like a flat surface. By overlaying the thermal liner with e.g. Wallrock Fibreliner, Wallrock Premium, Wallrock Trend textured paintable wallpapers (or even Paste the Wall Lining Paper) you can hide most of them. If you aren’t sure what these products are and what they look like get a free sample. Just drop us line.
If you don’t want to overlay the thermal liner with anything else quality filler very often does a good job of masking any problem areas.
3. Use Paste the Wall wallpapers
There are a number of printed wallpapers in the market that you might like and they are fine to use as long as they are paste-the-wall (sometimes called non-woven) wallcoverings.
Why you shouldn’t use normal lining paper or wallpaper
Lining paper or traditional wallpaper expands when wet and tries to shrink when drying. We call it dimensionally unstable. Wallrock Thermal Liner is dimensionally stable though. So, as lining paper or wallpaper is trying to shrink whilst on top of the thermal liner it can pull the corners of the thermal liner off of the wall. We don’t realise it, but the force exerted by the drying wallcovering is capable of it. That’s why you very often get gaps when hanging lining paper. You don’t get this when using Wallrock products as they are all dimensionally stable.
This is a question regarding wallrock thermal liner. Do I cover all the walls in the room or just the wall which is outside?
Hi,
The most cost efficient way is to apply Wallrock Thermal Liner (or KV600 Thermal Liner) to the outside-facing walls. This provides the best thermal insulation per £ spend. You could insulate the entire room, of course, but the inside-facing walls typically aren’t where the problem is. I hope this helps.
