Spray on external walls

gaz wac

Hey
Does anyone know what the name of the spray on walls is actually called?
Our problem is that, the whole side of our boundry wall is done with this, water must have got into it and when it froze, the plaster all fell off.
The area is wet to the touch, so I want to wait till the summer when it is dry, paint it with some sealer and then paint the wall as its black with dampness over the winter. Mang Company say there is no cash in the budget to fix so this will have to come out of my pocket, so looking for the cheapest option.

Thanks for any help

When you say "spray" do you mean masonary paint ? Or something else ?

? Monocouche is the name of the spray on plaster system of that's your question?

Metric Tensor

Monocouche is a brand name for a type of "Coloured Render".

Almost all professionals will know what you are talking about when you say monocouche but just be aware that there are other coloured renders out there so you may actually have one of those.

(Like Hoover and vacuum cleaner!)

thanks for the reply lads. Im going to try put up a pix so you will understand what im trying to do. Basically, when the wall dries out over summer, is there any waterproof sealant that I could use, then paint over it? Its just to make it look better as it looks terrible at the mo and I can get it replastered at a future date.

Really to do any sort of correct job it needs to be replastered. Anything else is only messing.

With that in mind - if you can't plaster it I wouldn't waste much money doing anything else. Others may have other options but I'd say wash it and give it a lick of paint and repeat every year until you can do the job properly. (Be careful if you use a powerhose because it will remove more of the plaster.)

Ok thanks MT......had a feeling it was my only option. Just had a proper look at it there and it is in pretty bad shape. crumbling to the touch and very wet as the grass level on the other side of that wall is prob 2-3 ft up from the path level, if you get me.There are only 2 sections that would need redoing, the rest is ok but would need to be cleaned and painted.


cheers for the replies

I didn't realise there was a different level either side of the wall. In that case even if you replaster the moisture coming through from the ground the far side will damage it again so you could be wasting your money.

The far side should have been waterproofed at a minimum before the ground was built against it. Having said that the wall does not look like a suitable retaining wall so it shouldn't be holding back ground anyway!

Do you own the land on the near side? Would you put a flower bed or something like that against the lower portion of it?

Think i'd wash it and paint it...

Metric Tensor

I think I'm with you Markcheese - if there's permanent moisture the far side it's not worth plastering.

Wash and paint - annually or bi-annually if you can get away with it!

Ok thanks. Ill give it a power wash in the coming weeks, let it dry and paint it. I believe the Mang Company will be looking at the walls in due time, so its just to make it look better in the mean time. Thanks again

Could/would you clad it in timber to make it look like a fence?

I was going to suggest a silicone based render, but you would still have the same problem I'd say with the dampness coming from the other side.

Alternatively, clad it in that stick on stone/red brick - you would need to check would the adhesive hold up though.

I couldn't to be honest as I don't actually own that side of the wall, the management company do and cladding would totally look out of place.
Ill do a patch job ( cleaning & painting) and wait to see if it will be repaired.


Cheers

Yeah agreed - probably your best option.

Be careful what you use - you may need to prime/stabilize it first. And will your paint affect whatever the Mngt company decide to do later?
