Can fresco painting be drawn with tempera paint?
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.
Why does ceramic slip stick to plaster mold?
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.
What is a painting painted directly on a plastered wall called?
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.
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.
Where can one learn how to install ceramic tile?
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
