I have just had a major problem.....
New skimmed plasterboard walls, dried for over 3 weeks.
Some Tetrion "deep" filling in a few places.
Applied 20% mist Farrow and Ball primer/undercoat, which went on fine with roller, brush around edges.
( as recommended by F&B for their emulsion)
Filled small indentations and small amount of flaking with Tetrion, sanded and dried.
Applied second coat of F&B primer, which has badly peeled and flaked in the vicinity of the filling.
Contacted F&B and apparently Tetrion filler is cement based and too alkali for their primer!
Any suggestions on how to fill the flaked areas completely flat, and what with, so not to have to strip whole wall and repaint!

Thanks Steve
 
F&B reply to that question:
  • Do you have your own recommended filler?

We don’t have any particular brands of filler I can recommend unfortunately but I would consider avoiding highly alkaline/cement-based fillers.

Pity this isn't stated on the tin !
 
You should have applied diluted primer/undercoat as you did the first time on the filled areas. Alternatively, and not necessarily safe, Toupret filler is not meant to need priming.
 
I try to avoid F&B paints.

Years ago i was using their emulsion and noticed that the pigment hadn't been mixed in properly. I was getting tiny red spots as I rolled the mustard coloured paint.

I phoned them and the snotty woman on the other end of the phone proudly proclaimed that it is a "characteristic" of their paints. She said that all of their paints should be stirred for 10 minutes before use.

I suggested that stirring it for a whole week would not break down sand sized grains of pigment- she didn't care.

Farrow and Ball- paints specified by people who generally know nothing about working with paints.

Most firms recommend diluting the first coat of emulsion rather than buying an expensive primer.. Nuff said.

Anywho, just apply something like Zinsser BIN over the problem areas. It is shellac/alcohol based and will prevent the moisture in the F&B emulsion reactivating base coats. It dries very quickly. Not cheap though. Clean brushes in cheapo household ammonia.
 
From the people I've spoken to (2 decorators) they say F&B is beautiful paint when on the walls and finished but an absolute a*se to work with -- they dread customers that request it.

I've used their colour swatch book to choose paint colours before but that's it. From what I've seen this is what half the people in Homebase do when down the paint aisle.
