new builds

[White Room]

quote ; wet the sand and cement plaster before applying the hardwall

Why put hardwall onto sand/cement on a new build ???

whitebeam it is a bungalow block walls sand and cement with finish skimcoat then tiled . dont know kind of addy was used, but i dont think it would matter anyway. maybe its been plastered with no windows or doors in. frost.

Depends what sand was used, I've seen soft sand used and it's so weak it would'nt hold up a knats d***

It could be that the Sand/cement had been left to dry then the finish applied which has sucked the moisture out of the finish

aqua just the areas that have been tiled is the problem. noticed in the house an awful lot of shrinkage cracks vertical, and horizontal going right across some of the walls.

is the blown plaster just in the tiled areas???

 

[paul damian]

yes doug .

 

[doug boardley]

imo then, it's been tiled before skim has fully set

 

[The Legend; Phil Hobson RIP]

Was the skim applied under 5 deg? same rule for adhesive, sand/cement renders, and gypsum based plaster

Either way I'd getting in touch with the builders:incazzato:

I think doug may be right....."my guess is it's been tiled day after being skimmed, weight of ties have de-bonded skim from basecoat"

Or the whole plasterwork is shot.
