There's nothing like a simple concise sentence - LOL -
If you have a drain in the room, power wash it, - if you don't it's going to mean a lot of scraping with metal spatulas and brushing with wire brushes to get it clean.
Good luck with it ..
Concrete Ways of Cleaning ConcreteOur users share their tips:For removal of moss, fungal or moss growths, a product called Bio-Shield works very well as an outdoor cleaner (as well as being the most cost-effective at 85 US cents per liter.) I have been using it commercially for 26 years and found it to be effective in cleaning up any exterior surface that is exposed to rainfall. (The product is only available online; see the Related link.) Once the affected surface has been cleared of lichen, moss or fungal growths, just respray it at the first sign of regrowth and it will stay clean.It also helps if you can keep the concrete free of tree debris, which will promote excessive moss and fungal growths.There are commercially available concrete degreasers that will remove some oil stains. However, as concrete is porous, oil will penetrate deeply into the concrete and won't be able to be totally removed. Apply the degreaser and then water-blast to remove the surface contaminants. On tough spots, the undiluted degreaser could be left on overnight - covered with plastic to slow evaporation - and then water-blasted again.What to avoid when cleaning concreteIt's not a good idea to use any acid on alkaline concrete - unless it is going to be coated or painted after cleaning. Acid cleaners will attack and dissolve the alkaline cement that binds the concrete aggregate together.(See the Related questions and Related links for more specific questions about cleaning concrete.)

Red-figured
the leading edge is black so that there is need for heat absoubtion.
So you can tell if the motor is turning (running) just by looking.
The drywall wasn't primed properly.

If it is just finished drywall then yes, it needs to be painted.
it means that the basement has just been painted different colors
Yes, you can by using standard tile adhesive.
Yes, concrete can be painted to change its appearance. Painting concrete is a common way to add color and style to surfaces such as floors, walls, and outdoor structures.
When selecting and applying concrete basement floor paint, consider these tips: Choose a high-quality concrete floor paint specifically designed for basement use. Thoroughly clean and prep the surface before painting to ensure proper adhesion. Use a primer to help the paint adhere better and last longer. Apply the paint in thin, even coats to avoid drips and ensure proper coverage. Allow sufficient drying time between coats and before walking on the painted surface. Consider adding a sealant or topcoat for added durability and protection.
Common causes of drywall damage include impact from objects, water damage, settling of the building, and poor installation. To repair drywall effectively, the damaged area should be cleaned, patched with new drywall or joint compound, sanded smooth, and painted to match the surrounding wall.
It depends on the wall. Grasshoppers don't have "sticky" feet like spiders, they have little grippers. A concrete wall? yes. A stucco wall? yes. Painted drywall? Probably not. They have to have something to grip.
Yes, you can use it....but what are you trying to do? The drywall primer is specifically designed to seal the drywall and make the surface uniform. You will not get any benefit from using it on top of a finish coat except for using it as a base coat for changing colors.
yes they can a lot of people will use neon paint to make them visable
Painted sheetrock, or drywall, is not highly porous, but it does have some degree of porosity. The paint creates a barrier that reduces the absorption of moisture and other substances, making it less porous than unpainted drywall. However, if the paint is damaged or worn, the underlying sheetrock can absorb moisture, which may lead to issues like mold or deterioration. Overall, while painted sheetrock offers some protection, it is not entirely impermeable.
