What is Wallrock Fibreliner?

It’s been on the market for a few years, but only recently started to become very popular with professional decorators and especially DIYers. Before we talk about Wallrock Fibreliner, let’s look at the good, old lining paper.

Lining paper is made of wood pulp – no surprises here. The fibres in wood pulp are relatively short, which means you can tear paper quite easily. This isn’t a big deal when you use paper for printing documents, photocopying etc; however, when it comes to putting it on the wall, it’s another matter as different things come to play. You won’t see it, but your walls and your house are constantly moving hence the cracks. So, when the movement becomes too much for the paper to take it will tear on your wall. Simple.

What’s the solution then?

Take the short wood pulp fibres and combine it with the long and durable textile fibres. Long fibres will ensure that the resulting material is stable, strong and it holds together well. Below you can see ‘naked’ Wallrock i.e. textile fibres – the image has been magnified. You can see long fibres going in all directions, which gives the final product ultimate tensile strength and flexibility. Now, dress it with  wood pulp and you have a wallcovering, which is:

  • very strong – it can take so much more of the wall movement
  • easy to hang (just paste the wall and put it up). It doesn’t shrink or expand when wet, which is the case with lining paper
  • you can paint it or wallpaper over it
  • it’s dry strippable and allows walls to breathe

Wallrock Fibreliner texture

Let’s compare the finish / textures of traditional lining paper 1200 and Wallrock Fibreliner – see the image below. The two finishes aren’t exactly the same, but they aren’t far off – these aren’t painted. Are you wondering why the lining paper is off-white? This is the professional range of lining papers which uses virgin wood pulp (from renewable forests though) and isn’t treated in any way. You might notice that lining papers made from recycled materials are whiter. The reason is that bleach is used during the production process to get all the ink etc out of the paper. Not all that nature friendly process then.

Lining paper and Wallrock Fibreliner – compare textures

When and why would you use Wallrock Fibreliner?

Quite a few reasons, but let’s look at the main ones:

  • Walls (and ceilings) that crack often and need to be reinforced. No lining paper will match the strength and durability of Wallrock Fibreliner.
  • If you are a DIYer, you don’t want to be buying paste tables just to do one room. With Wallrock Fibreliner you paste the wall and hang the wallcovering directly onto it. For those who don’t know, when hanging lining paper (or traditional wallpaper) you need to apply the adhesive to the lining paper first, fold it and wait for about 10 minutes before hanging it on the wall. At this point lining paper has expanded (it’s wet and that’s what paper does when wet) and will try to shrink on the wall when it’s drying
  • If you are a professional decorator, you can complete the job much faster.

How many Wallrock Fibreliners are there?

There’s only one Wallrock Fibreliner, but it comes in different roll lengths and widths – it’s part of the Wallrock range of products though and the name Wallrock refers to the production method that they are all based on. You can compare it to lining paper 1200 grade in terms of the thickness.

    Hello. I am using Wallrock Premium with the proprietary paste and I’ve found it very easy to apply except that I can’t work out how to tackle outside/external corners. I’ve tried various different methods but any case of rounding the corner with the paper leaves a strip of bubble up one or both sides of the corner that just can’t be worked out. Essentially, the paper won’t hold down around external corners, even with creasing (which quickly crumples the paper on non-plumb corners).

    This is the case even if a very large “overlap” is used, e.g. having the corner set in the middle of a 75cm sheet, with 35+cm on either side – the same problem occurs. Horizontal or vertical sheets, neither works well. I have experimented with a trimmed butt joint directly on top of the corner, but this is not neat and will surely catch and pull off once someone brushes against it.

    Can you please shed any light on how to get decent external corners with fibreliner? I have dozens of them to deal with!

    Thanks very much,

      Hi John,

      This is a typical problem with liners that are thicker and Wallrock Premium has extra fibres in its structure, which I suppose gives the material marginally more ‘spring’. Two things you could do:

      1. When you paste one side of the corner and apply the liner over it, wait until the adhesive dried and gripped it – you might need to wait for 12 hours though – before you apply the adhesive to the other side of the corner and bend the Premium. This could potentially work, but I’ve not tested it myself. However, if the corner is not plumb / flush straight you’ll still end up the end of the liner not being straight on the other side of the corner and requiring you to overlap and cut through.

      2. Another way is to to butt-joint on the corner, which you tried, but if you use a good filler (suggest Toupret ELAFIB or FIBACRYL – EXTERIOR Flexible Filler) to finish it off / close the corner you can actually get it to a very neat finish. When you are cutting Wallrock on the corner, just run your knife along the edge of the wall / the wall that form the second part of the corner, which will allow you to cut the liner exactly to the shape of the edge. This is especially true when the edge / corner isn’t flush straight. I hope this helps, but if you get stuck, please let us know.

    Hi, I have put some thin 2mm polystyrene veneer onto a cold external wall. The product suggests using wall rock fibre liner. Do I paste the polystyrene veneer then apply the fibre liner, or paste the fibre liner then stick,over the polystyrene ?

    Thanks, Hilary

    • OnWall

      Hi Hilary,

      You can do either, but you might find it easier if you paste the polystyrene. Wallrock Fibreliner is essentially a paste-the-wall type of liner, but works either way.

    I am proposing to use Fibreliner to cover embossed wall paper which has been painted with vinyl silk emulsion. The Fibreliner would then be painted with a soft sheen vinyl.
    The reason not to strip the wallpaper is because (1) the walls are plasterboard and (2) the wallpaper is sound and in good condition.
    Will this give a smooth wall look or will the embossed pattern show through?

    • OnWall

      Hi Desmond,

      I’m not sure if the standard Wallrock Fibreliner will cover the texture of the embossed wallpaper unless it’s very fine. What might be required is to use Wallrock R300 (Cosy Liner if a smaller roll is required) to do this. Happy to post you a couple of samples so that you can examine it properly.


  4. Desmond

    Thank you for your prompt response. I have requested a couple of samples.

  5. I am thinking of using wallrock fibre liner on a shower room ceiling and painting with eggshell. Will a constant use of the steam from the shower tend to lift the fibreliner.

    • OnWall

      Hi Ian,

      I’m slightly hesitant to say yes without knowing how efficient the ventilation is as the steam will hang under the ceiling for longest and it’ll be the hottest place as well. If the ventilation is quite robust, it could work, but I’d suggest that you size the ceiling using diluted Wallrock Power adhesive.


  6. Thanks for your response .there is a vent in ceiling directly next to the shower. In the case that I size the ceiling and a problem did occur ,would the fibreliner be difficult to strip from the ceiling.

    • OnWall

      In theory, Wallrock Fibreliner is dry-strippable so it should be easier than removing traditional lining paper, but in practice I think it’s similar. One way or another, it shouldn’t be too difficult, but you might need to use a steamer.


  7. Can I hang wallrock over vinyl wallpaper.

    • OnWall

      Hi Tim,

      I’d suggest that you strip the wallpaper off as the vinyl texture can be come off at some point in the future and most likely it’d show through Wallrock Fibreliner. We can always send you samples if needed.

    I am a professional decorator with over forty years experience. I have been impressed with many aspects of Wallrocks performance except for one, which is when applying emulsion to the dried out surface the finish appears patchy. This improves slightly after three coats of emulsion but is a little annoying as two coats with other wall coverings is usually sufficient. Many thanks. David Heeks.

    • OnWall

      Hi David,

      Thanks for your post. Wallrock Fibreliners are great to use and we have more and more customers who are switching to it from traditional lining papers. As for your comment, we’ve not heard this from our customers directly, so we had a chat with the manufacturer. They’ve only had a handful of these comments thus far and it seems that the issue surfaces up mainly during summer so they suspect the paint is perhaps thickening up and rollers and brushes drying out slightly which in turn allows the roller to lift fibres a little in patches where the roller is being pressed a little harder to make the paint cover. Once patches are like this, adding more paint does not always help whereas a very light sanding will remove the offending fibres. Wallrock Fibreliner Plus or Premium don’t exhibit these rare issues.

    I’m looking to use the giver liner to cover two of my walls in the bathroom before painting, as plastering will be an inconveniance. Will it be durable in the bathroom or would it tend to peel? Note the walls around the shower/bath are tiled and it would be the walls at the opposite side of the room.


    • OnWall

      Hi Francis,

      What sort of ventilation do you have in the bathroom?


  10. struggling to do external corners? any recommendation pls.

    • OnWall


      Could you please explain a bit more about the issue? Not sure how to comment / help.


  11. I used warlock fibreliner in my room. It looks great and solid.

    However, I have noticed at least two areas, where it seems plaster behind the paper is cracked and as a result paper has raised from the that cracked line area. It is very tiny/small line.

    Though paper is not cracked but I can see raised paper line.

    Is there any way I can push back the paper to wall?

    • OnWall

      Hi Mane,

      What’s started happening is that Wallrock Fibreliner has lost contact (due to cracking) with the surface underneath hence the slight lift as you described. Is this a new or reappearing crack? The only way to stick it back would be to get underneath Wallrock Fibreliner (depending on how far it’s from the seam you could try to lift it of cut through although the latter may not look good after you’ve finished the job) and apply more adhesive. Before you do so, you’d need to fill in the cracks though. Please consider our Toupret Fibacryl filler over the standard fillers. What I’d suggest you do is to leave it for as long as you can bear it to see if the crack develops further before you make any decisions.


    • I think it is better to wait and see.

      Re: Toupret Fibacryl filler, this is amazing stuff. We had a crack in ceiling, we filled it with different fillers but it was keep coming back. I filled it with Toupret filler weeks ago and it worked..

      One question I would have Fibacryl is difficult to apply as it is not possible to sand down. Any recommended way to apply this filler?

    • OnWall

      It’s a bit more difficult to accomplish, but try to part fill it, wait for it to set and then fill just the very top layer with a normal filler which would allow you to sand it down.
