How To Apply Plaster Filler Neatly
You can buy certain types of plaster filler in a tube with a pre-affixed application nozzle. These are ideal products to use when filling small holes in the wall.
However, if you find yourself with small holes to fill and only a huge tub of plaster at your disposal, have no fear. A plastic bag or zipper bag is all you need to apply plaster filler neatly. Cut off the corner of a plastic or zipper bag, add filler, direct the makeshift nozzle into the hole and gently squeeze.
You can also use this trick with cake icing.
