If you do not know how to plaster and want to get a smoother wall then you are in for a lot of filling & sanding. A good plasterer will make your walls super smooth and ready for painting or wallpaper.
Top Tip: A plasterer would charge on avg £450/550 to re-skim a medium-sized room! That will take a professional plasterer about 6-8 hrs to complete!
But, you can still get smooth walls without plastering them. Depending on the condition of your walls you can use:
- Filler and sanding
- Skim coating
- Lining paper
- Plasterboard – dot & dab
Filling and Sanding Your Walls!
If there is plaster on your walls and you want to make it smoother for painting, or maybe you have removed wallpaper and your wall is not smooth enough for painting. Then interior filler can make it much smoother!
Grab your self some good interior filler and a plastering trowel. Spr
You will want to keep the trowel at a steep angle because you are only filling the dent and marks. Continue doing this all over the wall until you think you have covered all dents and scuffs.
Leave your filler to set and make sure you have put enough filler on the wall, use your hand to judge if the filler has filled all the dents and scuffs. If the filler is set and you are happy with the result then you will need to sand.
Sanding is the main part of making your wall smoother, it will not be a plaster finish but will be good enough to paint. Use a pole sander and sand the wall in lanes to you know you have sanded the whole wall!
Lining paper can make a wall much smoother, but the wall must not have any marks or scuffs because it will show through the paper no matter how thick your lining paper is.
You can use flat, woodchip or embossed lining paper. It’s very easy to apply to the wall, start in a corner and follow the wall around making sure you overlap the lining paper by about 3 mm to allow for shrinkage.
Use normal wallpaper paste and use scissors when cutting the top and bottom when the lining paper is dry!
If you want a smooth wall then use smooth lining paper. Use filler on the wall so the lining paper looks smoother. Any bumps, dents or excess filler will still show through the lining paper!
PlasterBoard – Dot & Dab
Plasterboard is another option when creating a smooth wall. This is called dry lining, you dot and dab the back of the plasterboard and it creates a suction when pushed onto the wall.
This is a great way to make a wall super smooth without having to plaster it. Here is a video to help you understand how simple this process is:
Smoothing a wall takes time and elbow grease, from filling to sanding will take time. But it will work if you keep at it! Dot and dabbing would be your next DIY step if you do not want to pay a plaster to smooth your walls!
