Since our business has been running, we have widened our area of work further due to our name becoming more advertised and recommended. Our work ranging from smaller plastering jobs to new extensions and we have now recently been started to be called into work by bigger contractors working in government buildings to historical listed buildings and churches.
Our sevices are all general building works whether thats plastering, blockwork, brickwork, roofing, stonework, rendering, general carpentry, limework, leadwork.
The standard going off time from when it's first applied to the wall or ceiling is generally 2 hours. this can vary slightly dependant of the temperature of the room and how thick you have applied it also.
You could always use a soft filler
You need to apply a form of a pva substance first. what we use is blue grit, which is a branded name for plasterers grit. you use a paintbrush or roller to apply it to the artex after you have scrapped off any peaks to the artex. the drying time is still quicker than if on clean plasterboard, however you have more time with it. also as you laying it on, if you get it as flat as possible with less lines then there isn't do much you have to go over and start chasing your tail.
This could be due to range of scenarios. when the plaster was first laid and going off, if the temperature is too hot in the room then it doesnt give its natural curing/setting time and could potentially shirnk which leaves cracks. also the amount of timber in the house. as timber shrinks and expands due to temperature and if it's a new build especially as timber generally takes 6months before its stops expanding etc.
I would paint on a soverign sbr slurry mix first after wetting the walls down (instructions to mix ratio easily explained on the tub, that gives it the adhesiveness to stick to the original wall. then lay up your scratch coat as the sbr residue becomes justt slightly tacky. scratch in your lines once staffed. then couple days laters wet the wall down again and proceed to lay on your top coat as normal. both coats we mix at a 4:1 ratio of sand and cement with febmix added into the water before.
