How to Remove Polystyrene Ceiling Tiles in 2022 – Step-by-Step DIY Guide and Top Tips (UK Edition)

The 1970s have a lot to answer for in the interior design stakes. You only have to think of avocado bathroom suites and Artex to realise that. However, one of the worst decorating trends of the era has to be the compulsion to install polystyrene ceiling tiles.

These unsightly tiles have long since fallen out of favour and are considered a fire risk!

Unfortunately, they’re not the easiest feature to get rid of. Our simple guide on how to remove polystyrene ceiling tiles will make it as easy as possible to bring your home up to date – and improve its safety in the process.

How to Remove Polystyrene Ceiling Tiles – Step-by-Step Instructions

You might have noticed that we’ve listed ‘elbow grease’ amongst the materials you’ll need to remove polystyrene ceiling tiles. The fact is that this is a time consuming and tiring job.

If you do it, make sure you start the process at a sensible time. You don’t want to squeeze it into a Friday afternoon.

1. Prepare the Room

Before getting down to it, you must prepare the room for a messy job. Remove as much of the furniture and other contents of the room as you can.

Cover what remains, including the floor, with a tarpaulin or a dustsheet. For more help protecting your room, check out this guide on preparing a room for a huge mess.

You should then look to cover yourself. Long sleeves, gloves, goggles and a mask are a good idea for this job. If you want to know more about protecting yourself when DIY-ing, the guys at DIY Tips have put together a really handy guide.

2. Removing the Tiles

Set up a sturdy stepladder in one corner of the room. Slide your wide scraper between the ceiling and the tiles. Use your hammer to tap it as far under the tile as possible. Aim to break the bond between the tiles and the glue or adhesive holding them up.

To help the process, you can jiggle the scraper up and down to prise the tiles away. Always keep the scraper at a shallow angle to the ceiling. You don’t want to scratch or damage the ceiling more than you have to.

Pro Tip: How difficult this part of the process becomes will depend on how the tiles were put up in the first place. Some are glued all over, while others will only have dabs of adhesive in the corners or edges.

Either way, you’re better served by moving your ladder more often rather than overreaching and harming yourself.

3. Getting Rid of the Remaining Adhesive

You might not want to hear it, but once you’ve removed all the tiles, your job is only half done. Your ceiling will still be spotted with (sometimes fairly significant) blobs of glue or adhesive. You now have to work your way back across the ceiling, removing these devils.

What you’ll want to do is to gently warm up each blob with your heat gun so that you can then more easily scrape it off. Deal with small areas at a time, and then wipe your scraper with a rag to remove excess glue before moving on.

Pro Tip: Never get your heat gun closer than about 12-15cm from the ceiling. You don’t want to risk scorching the actual ceiling surface. For the same reason, it’s good to move the heat gun gently from side to side as you use it. That will ensure the heat doesn’t concentrate on one spot for too long.

4. Assessing and Repairing the Ceiling

Now you can see exactly what you’re working on with those horrible tiles out of the way.

Chances are, there will be some ceiling damage to deal with. Even if you were careful, removing the glue has probably taken off some of the old plaster. Note: polystyrene tiles were often used to mask an already damaged ceiling.

The best-case scenario is that you only have to dab some Polyfilla into small gaps or cracks. If your ceiling is in worse shape, check out our guide to patching plaster.

5. Finishing Up 

With the tiles out of sight and out of mind, it’s time to get the ceiling looking spick and span. If you’ve filled some small cracks and holes with Polyfilla, you’ll want to sand those areas to get them nice and smooth.

When the ceiling’s repaired and sanded, clean it with sugar soap or something similar. You’re then ready to finish the ceiling as you see fit.
