Try a heavy coat of primer/sealer. The primer should condition and adhere to your plaster walls. Once the primer sets up (dries) you can then apply anything you want to those walls.

Masons tipsI have had better luck with the poured ones afetr the forms have been taken off. Making sure as the concrete is poured/pumped into the wasll to use a concrete vibrater to remove air which will result in hollow spots and cracking.You can finish the walls easily with Grout,cement,or a type of mortar that has less shrinkagee but this type hardens quickly, so have your mason ready with sponge floats /hand floats,Masons hammer,protective gear for eyes, hands,rubber boots, to prevent exsposure to the wet cement that will cause a chemical burn.
my husband did our living ceiling by doing a textured plaster & spraying fine opalescent glass chips on it to get a sparkly finish.
Masonry nails have very small heads, and are notoriously difficult to remove from plaster, concrete, and wooden walls. The best way to remove them, without removing the plaster, is to cut the head off so that it is flat to the wall. Then, fill in the hole and repaint, if necessary.
The material of your walls can vary, but common types include drywall, plaster, brick, concrete, or wood.
Older plaster walls may contain lead-based paint, which was commonly used before the 1970s. Lead-based paint can be found in layers of paint on the plaster walls. It is important to test for lead before attempting to remove or disturb the walls.
Termites burrow into concrete block walls. Termites live in many types of structures. In addition to walls they also live in baseboards and slabs.
The standard concrete building block for load-bearing walls is 8 x 8 x 16
To effectively paint concrete block interior walls, follow these steps: Clean the walls thoroughly to remove dirt and debris. Apply a primer specifically designed for concrete surfaces. Use a high-quality paint suitable for concrete blocks. Apply the paint in thin, even coats using a roller or brush. Allow the paint to dry completely between coats. Consider using a sealer to protect the paint and improve durability.
To effectively waterproof concrete block walls inside your building, you can apply a waterproofing sealant or membrane to the walls. This will help prevent water from seeping through the concrete blocks and causing damage. Additionally, you can also ensure proper drainage around the building to divert water away from the walls.
It depends on the application. For homes, masonry is fine as long as it is insulated well against the weather. Masonry rarely needs maintenance. Concrete walls are stronger and last longer than masonry but are more costly to construct. For basement walls, I suggest that you always use concrete walls. Above ground level, masonry is cheaper and strong enough for residential and commercial, multi-story applications. For retaining walls, 8" thick masonry works well up to about 8 feet of retained earth. Above that, the lower courses of block will get thicker to 12". You still need concrete footings for block walls.

That's sort of a strange question. A concrete slab is a horizontal surface -- it's meant to be a surface you stand on or build things on. Concrete blocks are usually used for vertical surfaces -- walls. I believe that poured concrete walls are more expensive than concrete block walls. You wouldn't use concrete blocks as a substitute for a concrete slab.
To effectively remove mold from concrete block walls, you can use a mixture of water and detergent to scrub the affected areas. Additionally, you can use a solution of bleach and water to kill the mold spores. Make sure to wear protective gear such as gloves and a mask while cleaning to avoid inhaling mold spores. After cleaning, ensure the area is well-ventilated to prevent mold from returning.
