Kitchen paint vs Endurance paint

Two minds with but a similar thought at the very same moment! People will talk.

Reason being, is that you can put Silk over matt no problems, but unless you do this right you can have problems applying matt over silk.


If your ceiling is flat, then you need to sand down the silk, to get some of the shine off, as the matt will not sit on the Silk, specially if the previous person who painted the ceiling applied it on straight from the can, so when you apply the Matt onto Silk without sanding, when you start rolling it can lift off the orginal silk.
So if your ceiling is flat give it a quick sand down and thin your first coat by about 15%, so that it grips the Silk.

I'm sure your advice is well intentioned and possibly based on practical experience to which I would bow to, but from a paint chemists point of view I think your scientific rationale is way off kilter. I really do wish that painters would stick to what they know about i.e applying paint in a skilled way and don't try to interpret what is compatible with what based on a limited understanding of how paints are formulated. Silk and matt vinyl/acrylic paints are perfectly compatible with each other in any order providing you don't try to apply very thick coats. Much of the psuedo-science in advertising is marketing hype that is intended to confuse and make people buy something they don't need and won't see the benefit of. 10 years ago you might have bought Dulux Vinyl matt because it was washable. Now you have Endurance with claims that it is 20x better. So this is actually an admission that Dulux vinyl matt was never really washable. All it means is that if you wet it, it won't fall off the wall immediately! All I am saying is that you shouldn't believe the retail advertising or the "insider technical info" that is fed to the trade

We have an artexed ceiling but I have no idea of the age, It is not jagged - just a light swirl. So we thin down by 25% and then do two coats. Thank you so much again. I will report back!

Arf - have you any idea how pompous and condescending that sounds?

Silk and matt vinyl/acrylic paints are perfectly compatible with each other in any order providing you don't try to apply very thick coats.

Whilst you may be technically correct in the hands of the average DIYer (and some pros too) matt straight over silk WILL craze. End of. Your point might have something to do with MisGs suggestion of thining the first coat first so that it isn't too thick. But for speed, which is the key (if you'll excuse the pun), in painting I prefer the oil based undercoat / soft sheen route.

Much of the psuedo-science in advertising is marketing hype that is intended to confuse and make people buy something they don't need and won't see the benefit of.

Now there I do agree with you.

So this is actually an admission that Dulux vinyl matt was never really washable.

No it isn't and thats a very unscientific and rather illogical conclusion if you don't mind me saying so.

BUT do not just put the matt straight over the over the silk. It will craze. Rub it down first. Then a coat of soft sheen then your matt. Alternatively a coat of thinned (white spirit) oil based undercoat in place of the soft sheen.

This was the other things Chivers could have done, but didnt want to confuse him lol
But sometimes you can get away with a good rub down of the silk if its old, and apply a very first thin coat.
If you have you put on Silk first, then realised you didnt like it and want to go matt, then its new silk, and thats where the undercoat or soft sheen route is better.:)

Artha, am sure your post well meaning also, but from a professional dec's point of view and experience, no matter what the paint is made of, what keystone and I have said is so very true with regards to Matt going Silk

You do get tiny cracks all over the wall, like crazy crazing, sometimes the paint will peel also, so you either do a test area and wait and see what happens, or you do what we both have said.

With Chivers artex ceiling, he should be okay if he follows our instructions, and cant wait for him to come back and tell us when he's finished.:)

Thank you both for your help. As it is so hot today, I have managed to do the whole kitchen today as the paint has been drying so so quickly! I followed your instructions to the letter and it worked a treat! I am so so pleased as it is a great end to a nightmare which started over 2 months ago with a leaking pipe under the kitchen floor. Thank you thank you thank you
