Hot Melt Glue Though glue guns are most often used for hobbies and crafts, many users swear by them for sticking things to cinder blocks. Since hot glue warps paper, it's best for sticking solid objects to cinder block rather than posters and pictures. Curing time is fast: just a couple of minutes.
Mortar is a thick paste made from mixing cement, water, and sand. It's primarily used as a sort of glue when building structures with stone, brick, or blocks.
Command strips are the only thing I use. They stick well, they come off easily, and the paint doesn't come off. I have had bad luck with hot glue when the humidity changes but clear packing tape works best. I keep sticki clips up for my vocab wall and other things that need to be rotated or switched during the year.
*The best way to attach to a cinderblock wall is to through-bolt it (long hex bolt, nut, and washer(s)), although this is not possible in many situations. Personally, I have found lag bolts with lag shields to be only somewhat reliable in this application.
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.
Use concrete and masonry bonding primer. Do not use wood or drywall primer or self-priming paint. After priming, you can use ordinary acrylic-latex paint tinted to the color of your choice. Use interior paint on interior cinder blocks and exterior-grade paint on outdoor surfaces.
To what surfaces will Command™ Products stick? Painted, stained or varnished wood, glass, tile, painted cinder block, metal, and painted wallboard. Command™ Outdoor Products can also be used on smooth, sealed and finished surfaces including vinyl siding and fences, doors, windows, decks, gutters and trim.
Sleeve Anchors – sleeve anchors have excellent holding values in the block and can be used in all three sections of the cinder block with relatively high success rate.
One way to attach something to concrete without drilling is to use concrete screws. These screws are designed to tap into the concrete surface and create their own threads. This method is ideal for attaching things like shelves, brackets, and other small items.
Gorilla Waterproof Patch and Seal Tape 4inch x 10inch Black
A: This sticks very well when applied to dry block surface and pushed on so the sticky surface goes into the block surface. If applied to painted block surface, then pulled off, it may remove the paint, it did for me.
You'll need to use a bonding adhesive to encourage adhesion between the concrete and the other substance.
In this case, the cinder blocks will be stacked on top of each other until the desired height is reached, and then a specific surface bonding cement will be applied on each side. This will make them stick together, just like what mortar does.
Vinyl brick wrap, also sometimes called rough wrap, is a type of adhesive vinyl wall covering that adheres to rough-textured surfaces, such as brick walls. This can be used on brick, cinder block walls and sealed smooth concrete.
You'll want to use a lag bolt that will anchor to the cement and a masonry bit to drill the holes. Avoid the “Tap Con” style screws as they don't bite all that well into cement. Real lag bolts have a wedge that expands metal that grabs the inside of the hole.
Concrete blocks are glued to one another by construction adhesives such as epoxy, resin, mortar, etc. to build a complete structure.
Tapcons can be installed in concrete, brick, block and in the mortar joints between the brick and block.
I've had several people ask how to hang things on your cinder block classroom walls so it doesn't fall off (and what to use). Only TWO things work for me... hot glue and Mavalus Tape!
You can even wallpaper over tile and other slick, nonporous surfaces, such as concrete block, or synthetic laminate paneling. On many of these surfaces, you'll first need to apply lining paper, which is a blank wall covering that provides a smooth surface for regular wallpaper.
Attach wall adhesive to a collection of decorated clothespins and apply directly to cinder block walls. Try getting your hands on some long pieces of cork strips and attach them to cinder block walls, using push pins to display artwork.
Painting Concrete with a Roller
Rollers are the easiest way to apply paint evenly to floors and walls. The best paint roller for concrete uses a 1/2- to 3/4-inch-thick nap. The nap is another name for the fabric paint roller cover and the thicker the nap, the more paint it holds to fill cracks and crevices.
