Wall Sealer, Wallpaper Prep, Improves Wallpaper Paste Adhesion, for Absorbent & Plastered Walls, Mixes in 30 seconds, Covers up to 30m2, 61g

Using this product on your walls prior to hanging wall paper will make a big difference once you get started on hanging your paper. It both helps the wall paper to grip well but it also allows the paper to be gently slid into position before brushing out any air pockets and trimming the edges. Old style product but always worth using.

Tried this on chalky walls and it's really good no chalky residue left on my walls very pleased.

Seemed to work well

Brilliant quality, easy to apply and made wallpapering so much easier and there was no bubbles. Great value for money, 1 small bag goes a long way, I bought 2 bags, as the bags seemed small and thought I would need more than 1 bag. I was wrong, one bag was more than enough for the full room.

Good product
