Why is my paint peeling? PigletJohn?

Hello

Newly plastered walls. DH applied mist coat of emulsion then painted two coats of a Dulux matt emulsion on top (three weeks ago). So far no problem. I decide I don’t like the colour with worktop / kitchen so he paints two of the walls in Valspar Kitchen and Bathroom paint (colur-matched) with 24 hours in between each coat. Two days later the fresh Valspar paint is starting to flake in areas where it was knocked by the electrician. DH investigates (by scratching with his nail) and manages to pull a big section off, he described it like peeling a sticker off a sheet.

Can anyone shed any light? DH is irritated to say the least; he thinks our only option is to remove Valspar paint and paint again (with a normal emulsion rather than kitchen/bathroom paint).

The other walls which still have the Dulux on them are fine, it’s just the two with the Valspar on top.

Am I clutching at straws when I suggest it hasn’t hardened properly yet, and if he left it well alone it would be okay? We are on a tight timeframe to complete the work and the last thing we need to do is re-paint again.

How long did you wait after the plastering to paint? The plaster may not have been completely dry. Also did you seal the plaster before painting.

At least 8 -10 days before we painted (it was dry) and a mist coat was applied before the emulsion to seal it.

Only the two walls with the Valspar as flaking, the others are fine (its a large kitchen / diner / family room - so lots of wall area)

I have nothing to offer here excepts at I am in the same situation with Valspar paint and newly plastered walls. We did three coats of plain white emulsion 10 days after walls were finished. Then two coats of Valspar and it peeled off like a sticker when we removed the masking tape.

Alfie sounds like it is the paint then!
What a pain. Have you repainted?

TheRedWoman Fri 01-Jul-16 15:25:22

Was it the kitchen paint you used?

MyKingdomForBrie Fri 01-Jul-16 15:26:28

I would contact the company to ask them what is going on. Is there not a number on the tin?

Sounds like the Valspar isn't adhering to the paint cost below.
It may adhear with time, but may not (sorry, no longer upto date with the bases everyone uses these days).
If you going to put the Valspar on any other walls, it may be worth roughening bit with sand paper first. If you've got some scraps of plaster board or wood lying around, and both types of paint, you could try it out before committing to a wall.

Thanks Green

Ours was in a bedroom and it was the one that has the primer built in - it's quite expensive too! We have now put the masking tape on the skirting boards and redone that but not sure how we are redoing the adjoining walls yet as only one wall is coloured. I think I'm also going to give B and Q a ring and complain too.

TheRedWoman Fri 01-Jul-16 16:23:49

I complained to B&Q this morning, manager very unhelpful. I don't think he believed me!

We have the same problem with our kitchen diner. Plaster dry, sealed, then painted. It comes off in strips. I'm sure we used dulux.

I've never used valspar but I have read quite a bit about it peeling off like that on other forums

nannybeach Fri 01-Jul-16 17:11:29

Valspar was very popular when I was young, never heard of any problems you need to allow plaster to dry for several weeks, you say mist coat, do you mean watered down paint?You cannot be in a hurry with these things unfortunately.

Hope Pigletjohn is okay ...haven't seen him/her reply to a thread for a while. Hope it is just me reading the wrong threads and all is well.

Not sure if relevant but on our newly plastered walls, we have applied at least three mist coats before applying "proper" paint.

PigletJohn is fine - he has posted on at least one EU Referendum thread I've read.

megletthesecond Sat 02-Jul-16 07:24:26

I have peeling valspar paint too. It's meant to be durable, is it bollocks.

megletthesecond Sat 02-Jul-16 07:27:00

My valspar is on walls that have had wall paper stripped off them. Haven't been replastered and look in good condition.

PigletJohn Sat 02-Jul-16 17:20:54

So the Valspar is coming off but the Dulux is staying on the wall?

That's odd with a Matt emulsion (less odd with a silk, which has a shiner surface). No glue or wallpaper paste on the wall?

You say it is in the kitchen. How can I say this without sounding rude?

Kitchen walls are prone to getting a film of grease on them from frying and roasting. Not just splashes, it vaporises and condenses onto the walls and especially the tops of kitchen cupboards. It's very hard to get off because it oxidises and goes hard. Maybe that happened.

I think I would peel and scrape all the loose paint off, then scrub the walls with sugar soap and a nylon brush or pan scourer, then roughen up with 600 grade wet-and-dry paper (as used by car painters) which is very fine and will not leave visible scratches. Then wipe down to remove dust, and try again. it might be safer to paint the shortest wall first, and see if it works,

You can also ring the Valspar help line, it is a brand owned by one of the giant companies.

p.s.

I've heard pro decorators say that K&B paint is a con for DIYers, they like Eggshell. I have no personal opinion.

LadyFannyOfOmaha Sat 02-Jul-16 17:32:24

You need to use a primer. We had a similar problem and used Zinsser which worked well. They have a website zinsseruk.com with how to guides.

PigletJohn Sat 02-Jul-16 17:54:05

But you shouldn't need a primer for painted plastered walls. More work, more expense. The Zinsser products are very good for overcoming problems, but why is there a problem?

LadyFannyOfOmaha Sat 02-Jul-16 20:45:41

Our problem was caused because we'd moved into a new house and the plaster hadn't been left long enough to properly dry out before being painted. When we repainted it came off on the roller revealing bare plaster and what did stick bubbled. We'd had to move in a rush as the buyer of our old house threatened to pull out if we didn't move quickly.

TheRedWoman Sat 02-Jul-16 21:53:47

Thanks all.
pigletjohn the kitchen is brand spanking new...all of it (new extension) so definitely not grease related, the closest we do to cooking is boiling a kettle in a separate utility room for the workmen.

There's nothing else on the walls either, just the mist coat and dulux emulsion.

I've done a bit more research and it seems to be a common issue with valspar, I will give the helpline a ring. I will also show your suggestion to DH about removing the paint.

It's just frustrating, we are a week away from moving back home after 3 months with my parents and really could do without another job on the list.
