How to Remove Polystyrene Tiles
Removing polystyrene tiles or Styrofoam tiles as they are sometimes known from walls or ceilings can be a tedious job and unfortunately there is no easy way of doing it other than getting stuck in with a wide scraper to scrape the tiles off.
In most situations, polystyrene tiles were used to cover a surface, whether it's a wall or ceiling, due to the fact that the surface itself is poor. This can be either be that it's wavy and uneven or in some cases not finished at all.
As mentioned, removing the tiles themselves is not going to be an easy job, especially if they are on the ceiling.
The tiles themselves will have been fixed to the surface in one of two ways:
- Completely glued: The entire rear side of the tile is coated in adhesive and fixed to the surface
- Dot and dab fixed: A dab of adhesive is put in each corner of the rear side of the tile and also normally in the centre
If the dot and dab fixing method has been used this will make the tile removal slightly easier as you can use a scraper to pry up the un-stuck parts of the tile and pull them off leaving only the sections that are still stuck. You can then use the scraper to scrape these off.
Where the tiles are totally glued to the surface you will have no choice but to use the scraper to chip and scrape off a bit at a time until all is gone.
This can be a pretty messy job so make sure you cover any carpets with dust sheets and remove as much furniture from the room you are working on as possible. Also, be careful using your scraper! Don't hold it at too much of an angle, hold it as flat as possible, as you will end up digging into the surface of the ceiling or wall and causing more damage.
Although not the most inspiring of jobs this is the easy part. It gets tricky once you have removed the tiles.
Removing the Left over Tile Adhesive
With all the tiles now removed you may notice a large amount of the adhesive still remaining on the surface that now needs to be removed.
Again there is no easy way to get this off other than to break out the scraper and also a heat gun.
Warm the adhesive gently until it becomes soft and then begin to scrape it off. Wave the heat gun over the surface from side to side as this will ensure that not too much heat is concentrated in one area for too long. Hold the gun about 6 inches from the surface whilst doing so.
Continue to heat the adhesive and scrape it off once soft, Working in small areas at a time and once you have scraped the soft adhesive from the surface, wipe the scraper on an old cloth to remove it.
Make sure you are wearing the correct safety equipment such as a mask, gloves and eye protection. The act of warming the adhesive will most likely produce fumes that could be potentially dangerous if breathed in.
Once you have removed all the major bulk, you may notice that you still have some residue remaining. In some cases this can be removed by simply scrubbing hard with cloth or a scouring pad. You can also try a cloth and white spirit or a solvent thinner.
Again, make sure you are wearing rubber gloves, a mask and safety specs may not be a bad idea as you may be using solvents above your head. Please be careful.
With all the tiles and adhesive gone, before you go about finishing the surface with your chosen covering (paint, wallpaper etc....) it's always a good idea to get a plasterer in to skim it over as this will give you a nice smooth base to work with.
Damaged Wall or Ceiling Surfaces
After the removal of tiles and adhesive you might find that the surface underneath is rather less than good. If this is the case then you have a few choices:
- Replastering: You can replaster the entire surface to get a smooth, flat finish to apply your chosen top coat finish
- Plasterboard: With this option you essentially fix plasterboard sheets over the top of the existing surface and create a new wall or ceiling that can then be plastered and finished with your chosen covering. To find out more check out these projects here
The above plasterboard option can also be used to cover the entire surface without the need to remove the tiles in the first place. There are both benefits and drawbacks to this option such as:
- If the surface is in good condition under the tiles then covering it over will involve a fair bit of work and cash, when, with a little elbow grease and time, you could still achieve the same end result.
- Boarding the surface over and then plastering will, without doubt, give you a nice flat and tidy surface and ultimately, a great finish
