Remove Pebble Dashing And Rerender

[johonawhitness 110]

sharp + builders sand (can get as one forgot the name often called rendering sand),cement, lime, plenty pva. in correct ratios. 1 scratch coat 1 smooth. maybe longer but always lasts a good while and fully water proof for years once bit of paint ontop. big job but easy to learn if got the time spare

[Truther 1,579]

Its called "grit washed plastering sand" the old boys sometimes called it "river washed sand" supposed to be fit for purpose as it comes, but sometimes you need to riddle for the top coat, good gear if its right though.

I've an old property that we will be re plaster this summer. It's solid stone walls with lime mortar mix and a lime mortar wet dash on it. I've been warned about even painting the exterior with normal paint that won't let the walls breathe and dry out, all the moisture can only exit internally if sealed externally and will cause big damp issues. I'm hoping to re dash with a traditional lime mortar mix again to keep the old lads theory of the walls being able to breathe. Sealing everything up watertight isn't the answer in a lot of old buildings apparently.... I'm delighted to hear about that k-rend as that was a consideration for awhile!!

Well I think couldve written the book of damp at my place! had rising damp due to no dpc, damp due to crap gutters, damp due to roof issues, damp penetrating where the NPG bracket holds the mains cable on and now have damp in little uns room which I think is where the conservatory joins the house. On top of all that you can see the render is knackered and holds water.

SO, considering all that I figured rip it off and start again and make sure it is done properly.

I thought K rend was meant to be the bees bollox but thats second time Ive heard a bad review of it now.

Whats the answer then guys? sand and cement render with waterproof agent in? I had been told that werent meant to use sand and cement on no-cavity walls, supposed to use lime render to allow wall to breath????

k rend is over rated an one of the most expensive material out there forget sand and cement and there's no need to remove old roughcast can even insulate walls before scriming get some one in yo look at it and give there advice rather than listing to the comments on here lol

That's good advice - making an old building suitable for modern living is a bit of an art and different approaches to the way building is taught at college.

 

Would the building have been rendered / pebbledashed when it was built ? Exterior rendering was really a visual thing to cover up poor quality stone or brick in my part of England, plenty of buildings that were originally rendered have been fine for hundreds of years without it, so long as the pointing is good and rotten stones replaced. I always wondered if it was different in Ireland and Scotland because of the harsher winters.

If its a solid wall ( no cavity ) it's best to king span e,m,l and then a two coat render using seka water proofer.

That's exactly the way mine is done mate. 350 year old mill built with poor stone and lime rendered originally. I know a few guys that are experienced in renovating period buildings and they strongly argue with sand and cement on this type of building and assure me that it will lead to big problems with dampness. There theory is that the walls will breath and keep themselves dry and not weep if moisture can enter and evaporate in moderation both internally and externally. Even modern paints on the inside can effect the breathing and that's why breathable paints are available. To fing guys that do traditional lime mortar plastering isn't so easy!!

Where abouts are you d Lloyd

Shaun's your man he will give you a good job at the right price I am a builder and have seen his work spot on

[fox digger 1,086]

Any chance of getting a contact for them mate?

[gnipper 6,570]

Having some issues with penetrating damp and the dashing has cracks all over. Knew it was a problem when we bought the house but all this wet weather has brought it to the fore so looking to have it sorted this year. Double brick no cavity so normal sand and cement render Im told is a no-no. the newer waterproof and breathable types K.rend or similar are meant to be the ones to go for.

 

Anyone do this type of work, or have a recommendation around doncaster?

 

 

cheers

Did you get the render sorted mate?

[ryaldinhio 4,870]

Not yet fella. Arrival of little one meant money has been spent elsewhere. I think this year may be me up the ladder patching what I can with a view to saving up for next year.
