Polystyrene tiles updated question

[Rosie34]

We are hoping to rent out a property and have been told by a letting agent that the polystyrene tile on the ceiling of the porch (only exit) are not legal for renting purposes. Can anyone recommend a fire resistant product suitable for this purpose. (And also if this would be acceptable from a legal point of view)

Many thanks

PS Following Prentice Boy's advice, we have (or husband has!) removed the tiles which were completely stuck on and not just blobs at the corners!What he found underneath is wood, so now are wondering what is the best way to cover this. (This porch has a limited life span anyway as we intend extending the house in about a year or so) One idea is to artex over the wood but I am doubtful as to whether this would work. Or do we need to get someone to put plasterboard up etc?Any advice welcome

Thanks

Removal is the solution, they give off dangerous toxic fumes when they catch fire.
If your porch ceiling consists of polystyrene tiles only, after removal you should be looking at a product such as plasterboard for the ceiling.

Unless you can clean the wood up nicely, the best way would be to cover with plasterboard, scrim the joints and skim with plaster.

If you can't clean the wood up well, and you don't want to spend a lot, find a textured paint that gives a thick stippled effect.

Depending on the wood type and condition, you could clean it up and paint it.
The best way to remove any left over blobs of adhesive or residue is by heat, as the surface is wood a steamer would be a better option than a heat gun.
If you are going to knock down the extension, I would personally spend as little money on it as possible but obviously make it safe and aesthetically pleasing as needed for your tenants.
How large is the the area to be covered?

The area is aprrox 5ftx7ft

So at 5ftx7ft.
To plasterboard and plaster you would require at least two plasterboards.
As one 2400x1200x12.5mm is just a little small.
It could be possible to use 2no 1600x900x12.5 at about £5.00 per board
A 25kg bag of multi finish will cover this area with plenty left over at about £5.50 per bag, some dry wall screw pack of a 100 will do at £2.50 and joint tape at £5.00 a roll (plenty left over). and possible trim up the edges £10-12
So material cost of about £30.00-£37.00.
Not a big job to complete.
If you require the services of plaster could vary area to area but I would expect them to charge around £80-£100
So total cost between £110-£140.
Or the cost of a tin of paint if wood in good condition.
You could also consider instead of plastering, fitting a plywood sheet to the porch ceiling, trim and paint.
