The option for insulating concrete block walls includes spray foam insulation, injection foam insulation, polystyrene beads, foam boards, and loose-fill masonry insulation.

Faux Finish you can make that ugly cinder block wall look like cut, fitted stone or brick. Cut stone is simplest look to achieve because you follow the existing grout lines. For the brick look, youll need to fake some additional grout because bricks are smaller than cinder blocks.

Concrete. The simplest way to cover a cinder block wall is by using surface bonding cement to create a concrete finish. Concrete helps insulate the building and keep moisture out. It creates a smooth, finished surface you can leave as is or paint.

One is to dig the dirt away from the wall, twist some augers into the surrounding soil and use tie rods to pull the wall back into place. The other method uses steel I-beams that are installed on the inside of the wall. They are attached to the basement floor and the floor joists to prevent the wall from bowing inward.

The concrete blocks that are used to build block foundations are hollow. After the concrete blocks are laid, the voids can be filled with a cement-based mortar or poured concrete that contains small pea gravel….Do you need to fill cinder blocks with concrete?

Water is the primary cause for most crumbling concrete. Whether from flooding or from repeated rains, water eventually wears down the structure of a cinder block from the outside, causing it to flake off and crumble. If a block has not been properly cured, water can also infiltrate the interior of the block.

Paint the cinder block wall with a thick coat of masonry waterproofing paint, pushing paint into cracks and crevices of block. A paint roller or brush made specifically for masonry is best. Allow to dry overnight or for a minimum of 12 hours between coats.

You can stop pinhole water leaks in your cinder block walls by sealing them with a masonry waterproofer. Masonry waterproofers contain particles of silica or epoxies that bond with the cinder-block surface to create a waterproof barrier that plugs the pores that cause pinhole leaks.

Yes, you can plaster over paint, however, there are factors which should be considered first. If the paint on your wall is in good condition, then a professional will likely be able to start the plastering process straight away. Paint that is in ‘good condition’ won’t have damages or cracks and won’t be peeling either.

Anyway, you can plaster directly onto breeze blocks. You’ll need to float and set, (undercoat/top coat plaster). Use either Hardwall, Browning or sand and cement render for the backing/undercoat,, then finish with Multi Finish..

Mud over concrete does’t work. After a while it will show splotches of discoloration, then it will peel off. I’d suggest doing as the locals do and use materials they use. The right plaster can be smoother than drywall.

Apply joint compound to the concrete seams, sanding between coats as necessary, to achieve a feathered out surface, flush with the concrete surface, free of ridges, tool marks and sanding grooves. Apply a final thin coat of compound to the entire concrete surface.

Things You’ll Need You can glue drywall sheets to a concrete block wall. Drywall is usually attached to wall studs with 2-inch drywall screws using an electric drill with a driver bit installed. You can glue drywall to the interior of concrete block walls using a straightforward procedure.

Cover your bricks with it and use drywall mud to cover it. Just start floating it on and let it dry. Sand a little and add another coat and so on. It comes out looking like drywall and then you can texture it or just hand texture it then paint.

Place the drywall on the brick surface and use masonry nails driven into the mortar to hold the sheet in place until the compound dries. Once the drywall compound has set, finish the job like you would any drywall by using joint compound and tape to cover joints and nail holes.

Cover Up the Wall If you prefer, you can simply disguise and cover up that unsightly brick wall. Cover the exposed brick wall with fabric panels or with a single large curtain. You can also use adhesive to hang pictures and artwork directly on the exposed brick wall if you like.

Plastering directly to bare brickwork or blocks, known as ‘wet plastering’, is still favoured by some for its superior soundproofing. A cement render or gypsum backing (known as a scratch coat) is first trowelled directly onto blockwork before this is finished with a thin skim coat.

6 Answers from MyBuilder Plasterers If the walls are good and sound,then they can be prepped & re-skimmed although you will still run risks of new skim developing cracks on old plaster. You can tell if it’s pretty sound by knocking it with your knuckles in various places.
