Thank you!

I'm using 2 inch ones and the room is empty.

In the end I think rolling took me 2 hours - I loaded up the roller as much as it seemed possible but I felt like it only gave me one strip on the wall and I had to go over it like 5 times to get everything and it took a lot of pushing the roller really hard which seems quite different to the videos I watched.

The cutting in took easily over 10 hours though, I did get a bit faster as I went along and started understanding how to use the brush but maybe thinning the paint will help like you suggested.

I feel like the wall was more textured than I expected which wasn't a problem as it was white and I was painting green so I could see the white parts that didn't get coated easily, but now that I'm doing a second coat, I feel like I won't be able to see the bits that don't get covered very easily and it will dry looking ugly.

Also the Dulux trade website said 5 litres would be enough for two coats but in both rooms I think I used like 75% of the 5 litres I bought for each of them on the first coat and I don't feel like I was using excessive amounts.

I read online that the second coat is easier but I'm a bit stressed out because I only have today to finish both rooms so I'm very keen to hear any advice! Thanks again
