Unhappy Wall paint issue (holes in paint)

Hello,

About a week ago I purchased matt paint by Colours to redecorate my bedroom. When I was painting a specific wall with a roller I noticed that there were tiny holes that were not being painted over with the roller, no matter how hard I tried to get the paint from the roller into the holes by going over those specific areas with a little more paint, the paint would not go into them.

I have attached some images below. I'm also seeing a 'shine' on the edges of the wall.

I'm trying to replace a silk brown paint with a darker matt brown paint.

If anyone could help me with this problem it would be greatly appreciated.

Thank you.

Marksr will be in soon but it looks like you did not prep the wall. A light sanding or wash the wall.

It looks like there was a contaminate on the wall that prevented the paint from bonding well

I'd aggressively sand that area to make sure if any paint isn't bonded it will be removed. Remove the sanding dust with a damp rag and repaint. The 2nd coat should go ok. I couldn't make out the shiny edges but it might just be where it's covered better than the rest.

btw - welcome to the forums!

What nap roller are you using? Probably ought to be 1/2" with that texture on the wall. I wonder if it got sprayed with furniture polish or something odd.

I was thinking hairspray but whatever got on the wall is the likely cause. Not sure what size roller cover was used but concur that 1/2" would be ideal.

Hi,

Thanks for your help , initially I used a 9" roller for the first coat, for the second coat I switched to a 7" roller, both 1/4" (cover).

I forgot to mention that about a week before painting the matt brown paint, the silk brown paint was applied over a matt white paint. A bit confusing but I wasn't happy with the silk effect so a week later I attempted to change it. When the silk paint was on the wall there were no issues with it, apart from the fact that the masking tape ripped the silk paint off of the wall... Could this be the cause? As the matt white paint before all of this bonded with the wall well.

A 9" roller is fine but you really should use a 1/2" nap. 1/4" nap is ok for rolling slick wood [like a door] but doesn't hold or distribute enough paint to be very effective on walls. A 3/8" nap will also work on slick walls but IMO it doesn't hold enough paint and makes for more work.

It's not uncommon for masking tape to peel recently applied tape. I don't know much about silk painting.
