How to deal with stains

Following a recent job I did I thought I would do a post about how to deal with stains, in this case, water stains.

I had a call from a client who had a Velux window that appeared to be leaking and had stained the ceiling of their garden room.

After the roofer came and found the source of the problem, a broken tile, and repaired it I went back and decorated the room for them.

The source of the leak had been fixed and the water had dried out so I could start to decorate.

The first thing I did was identifying the stain by drawing around each stain with a pencil so it was easier to see when I used the stain block.

Once I had highlighted all the water stains with a pencil I used Polycell Stain Block to cover the stains, using a brush I painted over the stains, I knew how far to go as I had drawn around the stains. I covered the stains and pencil lines with the stain block, I then prepared the rest of the garden room by filling cracks to the walls while I waited for it to dry which took about two hours.

Once the stain block was dry I could paint the ceiling with white emulsion and the ceiling was as good as new, I then painted the walls to complete the job.

Another job and another satisfied client.

Always ensure the source of the leak is fixed and that you allow time for the water to dry out before decorating.
Some stains may need a second coat of stain block, allow to dry between coats.
Allow the stain block to dry fully before decorating.

Some people use an oil-based paint such as gloss, undercoat or satinwood to block out the stain, I have done this in the past but would only recommend using satinwood or undercoat due to it’s sheen level.
