Making Good (Patch Repairs)
Assess the damage
Check the area immediately surrounding the damage, if its loose then take it off if its strong then brush down the area with a hand brush to remove dust.
Controlling the suction
Dampen down the area(s) with your water brush
Apply backing plasterÂ
Fill out the area with your backing plaster
Rulling of then float up
If the area is wider than the length of your trowel the use a featheredge to rule off As you move the featheredge up the repair use a side to side motion. Fill out around the box This is a common repair Obviously the power should be OFF
Float the area with your devil float to key and close in.
Plastering
Prior to applying the 1st coat of finish you should have cut back the edges and scraped the surface with the edge of your trowel Also you should have removed any excess float coat from the good surface with the edge of your trowel.
Smooth out the first coat and cut back any overspill to the good area Apply the second coat and again cut back any overspill.
Cut out any overspill to the electric boxes at this point as some materials set very hard.
Flick water to the surface and trowel out Using the tip of your water brush Brush around the edge of the repair and trowel out Leave for a few minutes and dry trowel.
