Dot Dab Plaster wall - 35mm box? Plasterer at odds with electrician

[JLeague]

As part of my spec I said that I wanted 35mm back boxes. The walls have been taken back to the brick and will be dot and dabbed with plasterboard and then skim finished.

Electrician said that he can just screw the backbox onto the wall without digging into the brick because onces its dotted and dabbed the wall will come forward 35mm and cover the box.

Plasterer is adamant that is wrong and has said that he will do dot and dab but the wall will not come out as much so the boxes will protude.

I think I would have seen this by the out of line or plum walls, even when the front to the house was blown off during the second would war the rest of the house including the 9M floor beams survived, external corners are still plumb and are of the very small hand made bricks of the original vintage.

The place could have subsided and partially collapsed within 12 months of its first build and you have no clue as to this so to have an opinion on its integrity is optimistic to say the the least it could have been rebuilt several times in its 500 year old history.

They have an intimate knowledge and record of its 500 year old history.

Yes they have farmed this area for longer than that and where the original owners of the property we only say its 500 years old because that is the first time it changed hands, their records go back further than that.

This discussion has gone on long enough, the original post is about Dot and Dab plaster to paraphrase someones previous post.

 

[westward10]

I assume you can substantiate these 500 year old records or is it just hearsay from generations of dead people.

 

[Mike Johnson]

need to move on Westward, original post is about Dot and Dab plaster, but parish records back to the Great Plague and beyond.

 

[westward10]

I am just asking for evidence to you latter comment in #73.

 

[Mike Johnson]

Well the Great Plague was in 1665 that's 357 years when the local village around the church was burnt down, the parish records including the property in question is detailed as still standing, furthermore the doomsday book record also has detail of a property on the plot, any more straws you wish to clutch.

You may well believe this is the case, but new build houses move because they are inadequately constructed, as I have said earlier, I have been involved with some very high end housing and any cracking of the internal plaster would not be tolerated, unseasoned timber used in timber frames and internal walls, probably deck cargo brought over from, who knows where, during the drying process of this timber probably causes excessive movement and hence cracking, something the RICS, ARIBA, ICE and ISE have been putting forward as the reason for cracking in Court cases for quite a number of years. My flint stone house is over five hundred years old is built straight off a chalk strata bed and has no foundations and has not moved or cracked anywhere.

Movement isn't the only thing that causes cracking, temperature changes cause shrinkage and new builds suffer from settling and cracking due to temperature changes too.

Just a fact for anyone who's ever been on site. Natural materials aren't impervious to the elements.

Strange post, movement is the only thing that causes cracking, whether that movement is due to temperature or subsidence its still movement, If a material is not stable i.e. not seasoned then yes it will move with temperature changes, new builds suffer from movement due to material deficiencies compared to older building practices, brick and block rather than timber frames, just a fact for anyone who has been in the industry longer than ten minuets.

The only strange thing here is how you think you know absolutely everything about everything, and your very weird obtuse pedantic use of words. Everybody knows movement in terms of planes physically moving within houses and movement due to shrinking and expansion are usually referred to differently but you decide to lump them all in together. The same as how you decided to try to start a fight because someone didn't explicitly state that blown render should be hacked off even though literally everybody else understands implicitly that that's what the guy meant.

You're doing it for no reason other than that you can start silly debates with people, which have the end goal of making you look clever on an internet forum. Then when anyone challenges you you try to just shut them down so we can 'move on' - this is typical of someone who wants to espouse their own views but isn't interested in anything anyone else has to say.

I find it amusing. I would ask the question: if you're not interested and you know best why are you trying to discuss these matters at all? What purpose does it serve except making you feel like the online big man?

New build housing has shrinkage, settlement and cracks due to things other than poor workmanship and materials. That's a fact and that's all there is to it.

I don't know everything just more than most about construction methods, you can block my posts if you don't like reading them.
