Re: IRELAND

Hi Jenny
Thank you for the reply,I go back to the Josh days in 2010 ,can’t recall if anything other than Plaster of Paris was used. What got my attention, was you said it was way stronger than what you were using ?
Then Sunflower said that was all he used, Looking at the color of Sunflowers pours , and his goldband sack I assumed that was plaster of Paris.
Where I get mine at I noticed they don’t have anything called Skimcoat unless I missed it.
Its a battlefield out there again today. So when you say stronger I want some of that !!
Thanks

Re: IRELAND

Yes I’m confused too ;) Happens easily and often. It seems as though there are two types of plaster here in Ireland, I don’t know the difference really, Skimcoat is for plastering walls prior to painting, and Casting Plaster is for (as you know) making moulds or casts. But this Skimcoat stays quite grey in color, so if anyone is trying to pretty it up, may be a bit more challenging. I just noticed it said on the bag to use 13 liters of water to 25 kgs plaster, very low ratio surely. Nice chatting Gifter.

Re: IRELAND

Hi J
I am sure glad you mentioned Skimcoat,did some searching and found what you are talking about. Just to bad the closest to get some is 100 miles from me. I am going to see if they will special order it for me.
I don’t want to crank out just a bunch of quantity, I want the best I can do.An still keep it simple.
Thanks again

Re: IRELAND

It is a long story

nowadays, with goldband , you dont need all that hassle
that s the difference
in the old days , there were different plaster types and techniques
they had to be applied separately
that s where the ” skimcoat” comes in, as a more finer finish type of plaster on top of the raw plaster finish

What is the difference between skim coat and plastering?

In olden days of yore plaster was applied over wooen lath which gave the plaster something to adhere to . Thus a much heavier coat of plaster could be applied because of the space between the lathes. the next day a second coat was applied called the skim coat because it’s only purpose was to fill in the imperfections left from the first coat. fast forward to now the plaster comes in sheets much the same as sheetrock ex cept it is blue, and rightly called blueboard , after the hangers screw the bluboard to the wall and ceiling a team of plastererscome in and put a skim coat of plaster over the whol board, the joints require a heavier coat. After this coat dries in a couple of hoursor less the plasterers come back and apply a veneer thickness to the wall and dampen the plaster with a brush being waved in front of the board.Thus completing the plaster job. Now a oldtime plasterer like my brother-in-laws brother is a real plasterer and I was lucky enough to have him plaster my house when we built it, would walk off a job if they wanted him to use blueboard., as he is a old time plasterer who is an artist as he makes crown mouldings an other plaster designs on top of a coulple of inches thick.of base plaster. if you get a chance to see a real plaster job and a blueboard job you can tell the difference and both shine over sheetrock and compound job.

Yes would be nice if you can provide more background on the sort of plaster you are using, this skim coat type.Looked into it myself but hard to find technical information about it.
I think there is extra limestone in it, if so , that s good news, but again would be pleasant if you can provide some links or information on that topic.The same applies to Gifter, as there are so many types of plaster with all sort of additives, it can boggle the mind :)the main thing is , as far as I can tell, there has to be gypsum in it, the selenite, I learned to use the most basic things as they work a charme, but we can always learn moreAlso reading a gypsum book now, lots of techniques in there too, I go often a bit wild on the mixing, but basically it comes down to one part water and one and a half or two parts gypsum/plaster, fill a bucket with the water ,crystal water can be added , than the salt, sand, and hand by hand put the gypsum in and let it sit for a minute …than you can gently steer it as it becomes the working yogurt solidity, without bubbles or lumbs.the faster you steer the thing the faster it will harden so if using an electric drill or mixer you will get a thick soup that hardens darn fast that s why the builders use that also amongst other reasons..
