I suppose if you were doing a faux fresco you could use tempera paint, but this wouldn't be done using plaster but on paper in the same style. On plaster I don't think the tempera would work.
The plaster mold is very, very dry. When you pour, the clay slip is mostly water and the plaster mold sucks up the moisture quickly, creating a coating inside the mold. It's like pouring gravy onto a sponge...the water is absorbed, but the solids stay on top of the sponge if you leave it long enough. It's the same way with a plaster mold..it's a sponge. That's the reason you watch the pour opening and pour out the excess when it is the thickness you need. The plaster will continue to absorb until the clay pulls away from the mold naturally, yet it is still green.
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.
I think the word you are looking for is Fresco painting. However, traditonal fresco painting is done with oils, not watercolors...the watercolors can damage the plaster. Oils don't have the same properties that watercolors do and won't spread like watercolors in plaster.
If you are installing on a concrete slab, then make a sand bed with sand & cement mixed to a praportion of 1:25. Level the bed. Then make cement slurry by mixing water. Pour the slurry on the bed for about an area slightly bigger than tile. Place the water soaked tile & give light blows by a wooden piece. then repeat the same procedure for next tile. Next day clean the joints & remove all excess cement slurry which has come out. Rake the joints. Then fill the joints by slurry of white cement. After a drying period of 2 hours, remove the excess white cement slurry. Pour some water for three days to keep the joints wet. If you want to install on prelaid flooring tile, then first grind the existing tile surface to make it rough. Then make cement slurry with polymer additive. Then paste the tiles on this rough surface by applying 3 to 4mm of layer of slurry. Sanjay - nikiasso@yahoo.com
Gypsum and plaster of Paris are synonyms.
If you asking about plaster of Paris which is used for modling, moulds or casting a broken arm then water is all you add to the powder, if it's plaster for a wall in your house then the answer is the same water.
The word fresco ("fresh") involves working with fresh colored chalk (a kind of cement or plaster). It's quite a difficult technique, because you paint and plaster at the same time. Later, fresco secco, a paint made of caseine and putty, was developed to put on a dry plaster wall.
The darker the color of the road the more sunlight it absorbs. A white cement sidewalk is whiter which absorbs many of the colors making it cooler.
As footballers cover their rings with plaster to prevent injury so Kobe Brynt does the same thing.
Black asphalt becomes hotter than a white cement sidewalk by one thing. The reason it gets hotter is because black attracts heat.
no it is not the same thing usually
Black asphalt absorbs more sunlight and heat than white cement because it has a lower albedo, or reflectivity. The darker color of the asphalt allows it to absorb more of the sun's energy, which results in higher temperatures compared to the lighter-colored cement that reflects more sunlight.
A pound of rice and a pound of cement have the same weight, as they both weigh one pound. However, cement is more dense than rice because it takes up less volume for the same weight.
Yes it will, it's basically the same composition.
