Plaster Wall Repair
Plaster wall repair seemed to be a difficult and a messy job. One would still have second thoughts doing it because plaster wall repairing times might be too long to spare. But with the evolution of many products for wall plasters, plaster wall repair can now be easily done.
Whether one product claims to be the best from other plastering products, one most important thing to be considered in repairing plaster wall is to know the type of materials used for plastering. Always be sure that the same materials are used to make it effective. If different kind of material from the original is used (i.e. cement or lime), repairing plaster walls will most likely fail and no benefit will thus be gained from plaster wall repair.
To have better results in repairing plaster walls and get better plaster finishes, some techniques should be followed taking into consideration the damaged area, be it small or large. But for minor plaster wall damage like nail holes or cracks, a speckling compound (mixture of glue, gypsum plaster and water forming a plastic paste) can be used for filling them. Be sure to widen the hole to at least 1/8” using the tip of a small pointed knife and clean out loose debris. With the use of a filling knife, fill the hole with the speckling compound making sure that the filler is above the level surrounding it then levels it off. Let it dry before sanding with a fine sander then brush with a primer and coat-finish it. Same can be done for the plaster ceiling repair.
Considering the cracks in plaster wall repair is sometimes disturbing specially if they are vertical and horizontal and caused by earthquakes. This needs professional assistance but for minor cracks, many can be able to do repairing plaster walls themselves. Small cracks should be scraped wide open and deep so as to have a space for the filler. But first make sure that the crack is cleaned and moistened with wet brush before applying the filler for better adherence in repairing plaster walls.
For large areas, plaster wall repair should always follow the three- coating technique, the render, the floating and the setting and a good patching to achieve best results.
In plaster wall repair, always make it a point that the area is cleaned out of loose debris and dust. Dampen the area with a wet brush or a water spray before putting the filler so it could adhere better. Using a broad knife or spatula, fill the area with the plastering or patching compound as the render layer making sure that there is enough space for the two more layers to be at a level with the surrounding wall when done with plaster wall repair. Then score the surface with a nail or a speckling tool and let it dry. Brush away the dust and moisten the surface again and fill with the second layer about 1/8” below the level surrounding it, this now refers to the floating. Score and let it dry. Once dried and hardened, clean dust away and dampen it with water then fill it with the setting layer levelling it up with the surrounding area using a wet filling knife. Remove the excess patching using a straightedge across the surface. Let it dry and once dried and hardened, have it sand, then prime and coat finish with paint. Now, you are done with plaster wall repair on your own.
