Cheapest way to finish blocks?

[perky416]

Hi guys.

What is the cheapest way to finish the block walls of an outbuilding?

I was going to use timber cladding, but as it will be 0.6m from the boundary, it has to be non combustible. I priced this up at around £1400.

I considered render, but after being quoted 1k to have a 10sqm ceiling skimmed i think having 50sqm of wall rendered will cost a fortune. I can plaster but have never rendered.

Can the timber cladding be made non combustible easily, or what would be the cheapest alternative to finish the walls?

Thanks

Paint.

You can buy a flame retardent coating for wood that you brush on, you'll need to check if this is acceptable to your building inspector

I was hoping to avoid building control thats why i want it non combustible.

Paint is a good idea, however i wanted to hide the block appearance. This could be a good back up option though.

You can get paint grade blockwork that is smoother than normal blocks.

Cement cladding like cedral. I don't think particularly cheap but maintenance free etc. If you can only see the front then as said the back and sides could be neatly pointed and painted.

I thought that. Skimmed it myself in the end. Didnt bother getting any more quotes i assumed that was the price of plastering these days. I might get some quotes for the rendering.

Nah, it’s about 300-400 round here. Or less if it’s literally 10m and an easy in out job

Its 10m x 50m!

If BC is not involved why are you concerned about it being combustible? People put wooden sheds near the boundary...

Render it yourself. Rendering is easy enough, it's making it not look ****e that's the skilled part.
If it's on a boundary then you won't have to look at it afterwards.

Slap it on!

That's fine if they are less than 15sqm, however if they are over 15sqm they attract building control.
One way around that is to make the external walls non combustible and keep it below 30sqm instead, which I assume is what the op is after
