High suction browning was brought in for high suction blocks ,it was more expensive than the normal browning, drying I think was not any faster butihave not used it since early nineties.

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 !!!!!!!

at easter i have been plastering for 50 years the only job i have ever had.
high suction browning,was a carlite plaster it was better then browning . but at that time there was a lot of low suction blocks, leca and leca fine.
there was also thistle browning and thistle fibre browning that you had to put through a cement mixer and add sand. then clean the mixer out every hour.

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

Cant beat sand and cement and skim finish, done properly its the best finish imo. Even hardwall and skim is a nice finish. Float and set all day long lol

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

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.

Leave for at least 5 days to cure. There's no need to PVA before skimming :)

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:

If it was my prefrence and doing a whole house id start at the the top and float all the way through with sand and cement, then drop back and skim when its cured proper, if its just a day job Harwall and set all day long.

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.

float and set is messier(hardwall) but nicer finish imo as is s/c , my fav, nicest to use,cleans up a treat , more solid than dot n dab, your house dont sound hollow and horrible like cheap new build.

Technically 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.

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 wall
