How to keep posters from falling off concrete block wall.
Depending on the paint i like hot glue.
Dorm rooms and classrooms are well known for having concrete walls that refuse to hold tape when you re trying to hang a poster.
The easiest step to remove efflorescence is to wash the wall and scrub the area to see if the stains go away.
I ve already told them that i think they need to have the roof checked i suspect the moisture is coming in from the top but beyond that i m looking to pick people s brains about the best way to approach recoating the exterior.
You will need to use only clear water to avoid worsening the situation.
Clean the wall with rubbing alcohol then peel off the paper backing from the adhesive hook and press in.
Masonry walls whether built of stone brick or cement all absorb moisture and react to stresses due to their weight and age.
The wall certainly looks unstable and ready to be taken down but a lot of concrete walls can look terrible but still be structurally sound.
Put down a base of making tape.
The sooner the better as time will be against you if you are trying to remove these stains.
Ignore any rebar you come across and just break the concrete free of the metal.
Damage free adhesive picture hangers come in a range of styles and sizes.
We owned a house with a concrete block wall reinforced with rebar that had perhaps a 10 degree lean outwards that looked like it d fall any day but it took a lot of sledge hammering chiseling jacking.
No holes in my poster no sticky residue.
Break the concrete wall into small chunks with your preferred tool and let the debris fall to the ground as you work.
Wow there is n.
Foundation all concrete block walls must rest on a sturdy foundation of poured concrete.
When inferior or inappropriate.
The depth and size of the foundation will vary depending on the size of the concrete block wall and the weight it must support but a typical freestanding wall requires a foundation that is about twice as wide as the wall itself and which extends about 1 foot down below the frost line.
If you use a laminated poster it just peels right off when you want to take it down.
If you are a student or teacher you may be discouraged after hanging the same poster board 15 times only to find it on the floor the next day.
If the concrete block wall is painted and has a relatively smooth not porous finish hanging pictures may be as simple as installing removable adhesive wall hooks.
This will keep your posters from constantly falling off your cement block walls.
And it just peels off my classroom s paint.
