Repair to a tenement stairwell which had suffered water damage causing the existing plaster to crumble, blister and fall off the wall.
The aim was to repair and re-instate to match the undamaged section of stairwell.
The first task was to remove all the loose plaster and paint all exposed areas with pva glue to seal all the dust and create a sound surface onto which Undercoat plaster could be applied. On the corner all the old plasterwork had to be removed and plasterboard was glued to the wall to reduce the amount of plaster required.
Once the undercoat (bonding) Plaster was dry the wall was again painted with a pva primer and then skimmed with finishing plaster.
Once dry the wall could be sealed with emulsion, then gloss paint was applied to the lower half (2 coats), finally, 2 stripes were applied using masking tape as a mask.
