First thing to do is put a tarp underneath you, so all the work will fall on top of the tarp. Always wear a mask, because you never know what is underneath a wall. Nails in a wall, can really create havoc, after years of putting nails in walls in different places a wall can begin to buckle. With your hand just go over the wall and feel it for buckles, either mark the spots with a pencil or rip the spots out, as you go along.
An averaged sized hammer works very well at removing the wall pieces. Just hit the areas that are buckling with the hammer and pull the pieces out with your hands. Once the wall is removed, you will be “making a key.” You can use a knife, razor knife, screw driver, to remove particles underneath the removed wall. Just go along the groves of the brick with the knife and scrape off the particles. Anything can be placed on top of the bricks. Sheet rock, wire, wood plaster.
However on older buildings some people prefer to restore the wall to its original condition. However whatever you want to use will work for you. Once all of the stucco is removed from the bricks underneath the removed wall, a bonding agent is put on top of the bricks. A bonding agent can be applied to the entire area with a brush, the idea of a bonding agent is that it kills all the dust under there, and makes the stucco adhere much better.
Apply by spreading hot mud AKA plaster to the brick wall, apply it smoothly and evenly to the wall.
It must be evenly and thoroughly applied to all the “keyed” areas. Apply a second coat too, to make it extra strong. Even out the plaster, to make it smooth and even. Let it set for about 15 to 20 minutes, after the wall is set, you float the wall, by using a sponge like tool, that basically flattens out the surface and moves the sand around to make an extremely even finish on the wall.
Once everything is set and dried it is ready for a coat of paint. This technique will work well for any type of plastering that needs to be done. There are different types of plaster that can be used. However the hot mud variety is very strong, much stronger then a more average type.
The floating can take about an hour depending on how big of an area is being repaired. You should always wear a pair of gloves, garden type are the best for this type of job. Once the floating, which is spreading out the plaster evenly using a sponge like tool. The sponge is attached to a square metal surface. Some water is applied and the surfaced is smoothed out. Once everything is dried, the wall is ready to be painted. The buckles are gone, and after it’s painted with matched color, the wall looks like a new one.
