What happens if you paint acrylic over oil - will it cause any adverse effects or damage to the painting surface?
Painting acrylic over oil can cause adhesion issues, leading to the acrylic paint peeling or flaking off the surface over time. This is because acrylic paint is flexible and may not adhere well to the rigid surface of dried oil paint. To prevent this, it is recommended to apply a primer or sealant before painting with acrylic over oil.
What problem does grade D plaster cause for paint?
Grade D plaster has a high moisture content and is often uneven or poorly finished, which can lead to issues when painting. Paint applied to such surfaces may not adhere properly, resulting in peeling or flaking. Additionally, the uneven texture can cause a blotchy appearance, affecting the overall aesthetic of the painted surface. Proper surface preparation is essential to mitigate these problems before painting.

In oil painting why shouldn't you dry painting in the dark?
Because this would cause a thin film of oil to rise to the surface, yellowing it.Sometimes, when oil paintings are dried in the dark, the painting can yellow. This is because a thin layer of oil can come to the surface as it dries. Drying it in daylight will avoid this from happening.

Why does paint peel on walls and surfaces?
Paint peels on walls and surfaces due to factors such as moisture, poor adhesion, or improper surface preparation. When moisture seeps into the paint layers, it can cause them to separate from the surface. Poor adhesion can occur if the surface was not properly cleaned or primed before painting. Additionally, painting over surfaces with existing issues like cracks or bubbles can lead to peeling.
What is fimbriae made up of?
Fimbriae are hair-like appendages on the surface of some bacteria. They are primarily made up of protein and help the bacteria adhere to surfaces, including host cells, in order to colonize and cause infection.
What would cause a Diamond Brite pool surface that has been recently installed to not adhere to the original plaster surface and start coming up in sheets?
You say that it did not adhere to the original plaster surface. That being said the proper prep work required when plastering over an existing surface was not done properly. Diamond Brite as well as other exposed aggregate finishes would not come off in sheets unless the applied surface was not properly prepped. Without knowing the condition of the existing surface I won't be able to tell you weather the finish should have been sandblasted or if it were structually sound enough that a acid wash, pressure wash and bonding coat would have done the trick.
How can I effectively preserve and protect a painting on cedar wood?
To effectively preserve and protect a painting on cedar wood, you can apply a clear varnish or sealant to the surface of the painting. This will help to protect the painting from moisture, dust, and other environmental factors that can damage it over time. Additionally, you should avoid exposing the painting to direct sunlight or extreme temperatures, as this can cause the colors to fade or the wood to warp. Regularly dusting the painting with a soft, dry cloth can also help to keep it in good condition.
Can you paint over chalk without any issues or preparation?
No, painting over chalk without any preparation can cause issues like poor adhesion and a rough finish. It's recommended to prime the surface before painting over chalk to ensure a smooth and durable result.
What is the water tension?
Cohesive forces between liquid molecules on the surface cause a phenomenon known as surface tension. Due to the lack of surrounding molecules, surface molecules adhere more strongly to another than they would inside a liquid. Surface tension is measured in newtons per meter (N/m) or dyne per centimeter (dyn/cm). The formula to figure surface tension is gamma equals the ratio of the surface force to the distance along which the force acts or gamma = F / d. Variables such as temperature and solution purity can cause F to vary. Pure water at 20 degrees (C) has a surface tension of 72.8 dynes/cm.
