rain going through wallof shed

Tomjim

When it rains heavy the rain goes through the wall of the shed (it's a blocked wall that isn't plastered) is there anything you can put on the wall to stop the wet coming in - I don't want to plaster it

Say my name

Bitumen paint.
Even parlour paint or any rubber based paint.

Could u plaster it ? Include the water proof , blocks are porous

Lime-wash seals the pores protects from mould and throws off moisture quickly and non-toxic, biodegradable, cheap.

Where would you get lime was

Could you make it by mixing a bag of lime with water

What size of wall is it. Length and width.

Tomjim

30 foot long 4 inch block on side 10 foot high

Will the bitumen paint stop the rain coming in.

When I have the sheep in for lambing and theres heavy rain, the floor gets destroyed and the bedding gets very wet, will the bitumen paint stop this

Would of thought no brainer to plaster with the waterproofer added to the mix.

Might sound like a stupid question but do you have a gutter on the shed. We have a old shed here and the gutter got blocked with leaves. The rain water spilled over and seeped under the wall into the floor.

Tomjim

would you have to plaster both sides of the wall, how much plaster would need to go on, there is a crush on 1 wall, so plaster would need to be minimal

Mixing your own limewash is the most economic way to do it though you can buy all kinds of expensive "ready-made" limewashes from specialists like The Traditional Lime Company in County Carlow.



The simplest way is to buy a tub of mature lime putty from the co-op or general builders supplies. Wear eye-protection as lime can be dangerous if it splashes in your eyes. Add water slowly, stirring, until the mix is the consistency of thick cream. Wear goggles or something to protect your eyes when applying it to the walls. I find a churn-brush works it into the stone. It looks like "just a wet wall" at first. After about 12 hours it begins to whiten. After 24 hours its dry and then if you choose, you can give it another coat though one is plenty for sheds. As well as sealing the blockwork it stops mould.

Are you sure water isnt coming up from below? cant see 4 inch block on side letting in that much water

There’s specific stuff you can get in hardware shop for this to prevent damp ingress. It’s expensive at about 80 quid but it works. Ever build aquaseal. You basically paint it on. Ask the hardware guys which one to get there are different ones depending on what you’re applying them to.

i have used that a few times and its great. the water beads off it. but its designed as a last resort not as a substitution for doing the job properly. i dont think it would last either if there are cattle rubbing against it.

assuming you have gutters and the yard is falling away from the shed then plastering shuld stop it coming through the blocks.

The outside of the wall needs to be plastered. A neighbour build a shed last year only got it plastered it recently. The amount of water it would let in was unreal, especially at the joints. Now the outside plaster can be wet but the inside is dry.

If you use lime wash you will need more than one coat the first time. You will probably need three.. mixing it too thick means it will flake down the line, but too thin takes 4-5 coats first time.

However similar to limewash you can paint it cement. It a messy job. Go on to YouTube and Google ''paint it with portland''. This will seal the wall like plastering. I say you could add the aquaseal or polybond to the mix in the final coat. I have used aquaseal (I think it was called Johnson aquaseal what I used) and it a good job but on a plastered wall nesrly 30 years ago. I painted over it and it still works.

Limewash is grand but you will have to do it every year. I definitely give the cement wash a try. I have a house washed and I going to add some white cement to the mix next year to make it more waterproof.

Plastering is the solution, you can forget about it after , no need for any maintenance.
