dot and dab has been out quite a while now, i can remember british gypsum running corses on it in about 1966.
how long have you been plastering 4 malc.did u ever work with hsb.a think it was brought out so they could get the painters in faster.years ago.hsb=high suction browning.
I can remember being taught a d&d system in 81 and it was a nightmare dots of adhesive with a plastic pad about 75mm square set to them and u had to use levels and lines to set all the dabs and then the boards were fitted mechanically with screws or nails i can't remember which. but it was a nightmare and the only time we ever used it was the day we were given the training on it !!!!!!!
Remember eml plaster for .......eml:RpS_laugh:
carlite metal lathing? they tell you to use thistle bonding now
is this not also called plumb and dot? you then screed of the dots when they had set , i have done this b4 was told i was on price after the first house , not likely dont get me wrong looked well but never going to do this on price!!there was a time when on first class plastering you stuck pieces of wood ,dots, on the wall , level them all up and rule the floating off them the next day. that idea went out the window the day piece work started.
we also used to dot floor screeds. it was quite nice to screed off dots
I worked on a housing site a few years back where we dot n dabbed upstairs and float and skimm downstairs.
How long do you guys leave the float (cement) until you skim. Pva day before or hour or two before?I'm more used to working with lime but have a house to do and it's up to me so I'm going for f + s in cement and multi
The dottng of floor screeds was how i was first taught to do them and the method your talking about for the walls i had to use on a circular room about 2 years ago then run a screed top and bottom and float it the next day ! happy days :RpS_lol:there was a time when on first class plastering you stuck pieces of wood ,dots, on the wall , level them all up and rule the floating off them the next day. that idea went out the window the day piece work started.

Board and skim. Because its cleaner, quicker IMO, and because the majority of properties I work on are solid walled so allows me to insulate external, dab internals. Much better job imo. No end of problems if you have solid finish internal and external on solid walls.
Because of breathing problems??
What was the reason for that:RpS_confused:.
Leave it a few days some walls take longer than others, depends on the blocks. I was always told to test it my scratching it with a nail when you think its ready, if it leaves a white scrape go for it if not leave it.(hope that make sense) Def dont pva it, only ashing for problems, just make sure its well keyed from the devil floating. Some times you need to dampen the sand and cement other times not just depends on the drying.How long do you guys leave the float (cement) until you skim.

Any one else got any thoughts on the house breathing if you float and set in cement and cement render the outside....would this cause damp. Can't see how plasterboard would be any better as your still putting gypsum on top
Skimmings very skilled done properly and dabbing boards isn't easy most dry liners can't dab same as edging a wallTechnically a solid wall has more benefits and advantages than a plasterboard wall (if done properly substrate prep to the finish). With regards price, dot n dab will always be the solution for low budget systems and plasterers who want to turn around jobs quick. Personnaly i prefer float and set. Either way u should be able to give the customer the option of cheap n cheerfull or long lasting and durable. No plasterer should be qualified unless they can float and set to 3ml tolerance over 1m. Sticking boards on walls is not skilled work and skimming 'to board' is not really something i regard as skilled either.
