Satinwood and raised grain

[voteforpedro]

Hi.

I'm getting a weird finish on my shelf using Dulux Trade Satinwood. I think it's raised grain?

It's hardwood, previously varnished. Here's what I did:

Stripped varnish with carbide blade
Sanded 40, 80 then 120
One coat of Dulux undercoat and primer
Sanded 120
One coat of Satinwood
One coat of Satinwood 18 hours later
Noticed this issue, so gave it another coat 18 hours later

12 hours later I'm still seeing this. Any clues?

It's not raised grain, it's paint checking.

Did you apply thick coats?

Are you using all water-based paints?

What was the temperature and humidity while drying?

Are you sure the wood is not veneered?

Second coat applied too soon.
That's not waterbased paint.

Recoat time ( not drying time) is 16h? I think it needed longer.
Leave it a week and then 320g sand and another coat might sort.

It's oil based. Says on the tin 16-24 hours. Although it's an unheated room as the radiator isn't connected so maybe I should have left it longer?

Okay thank you.

First coat was thin, second and third fairly thick. It's oil based gloss but the primer was water based.

There's no radiator at the moment so maybe 12-14 degrees? Should I have left it longer?

As others have said, it looks like you applied the second coat too soon.

After it is hard enough to sand flat, you can add some oxidising agent to the paint to speed up curing times.

eg terebene

Terebine Driers

Additive which speeds up the oxidation/drying process of traditional oil-based alkyd coatings.

Modern oil paints are thicker and take longer to dry. Times quoted are average but you need to consider environment.
Yeah. I had that happen to me in 2010 when the voc changed in paints. Probably wanted 2 days between coats

The second of Jan 2010, I recoated a cabinet that I had painted for a customer 7 years previously. I turned up the following day, the paint was still tacky.

From that point onwards, over the colder months, I now routinely add terebene. I had never used it prior to 2010. That said, after a couple of years, they tweaked the oil based paints to act more like they did prior to 2010.

I now add a tiny bit of white spirit, terebene and owatrol oil. Previously, I only added Owatrol oil.

Not use oil gloss since 2011 although have used the trade oil satin a few times.

Found that ok but the constant spec changing of the formula worries me so I try and stay away
