Most of the builders we have used over the years are totally clueless when it comes to building materials for old buildings. They recommend cement repairs for everything and it will cause a lot of damage to countless buildings over the coming years. Sad to see.
To be expected, they're tradesmen, not craftsmen.. the little formal training they do get (as an apprentice some 25 years ago in most cases) doesn't cover traditional building materials or techniques. Their main mission is to be cost-effective & functional, not to be respectful to the age or aesthetics of the building. So, the responsibility lies with the homeowner to seek out traditional craftsmen for the job, or simply DIY/bodge it as would've happened historically.
Let's be honest those historic tradesmen would've taken cement & gypsum products on in a heartbeat and were likely just as clueless to workings of the materials as a modern (post-ww2) tradesman is.
Spawling we call it and it’s everywhere. Unfortunately in a monetised society we can only advise owners on the best methods of repair, ultimately its cost that wins out.
That was interesting. Hope for more videos like this.
Hello wanted to ask, in your opinion is possible to use cement (for better setting) with hydrated lime and sand (0,5:1:5 ratio) for rendering a brick wall layed with lime mortar, as it is quite difficult to find hydraulic lime in our region?
Or even small amounts of cement will trap moisture, make wall unbreathable and ruin the bricks?
Kind regards
Looking at thr building worker and current building practice at the moment...I can forsee issues in the future...but no one listens
50 years later everyone realises it was a bad mistake
You cannot tell anyone who knows it all but knows nothing
Anyone know of someone who can do lime mortar building / repairs in Sussex area?
The corroded steel steel band needs to be removed from the defective brickwork
They expand over the years & are very problematic
