ᐅ Patchy finish with emulsion paint – should I apply a second coat?

Hello,

I have an issue with the coverage of my interior emulsion paint (from Brillux, Super Latex). The walls are made of drywall, which I primed once with a white primer beforehand. After that, I applied the emulsion paint once with a roller without thinning. Unfortunately, it did not fully cover, and the result is patchy in some areas. Now I want to repaint it with the same paint.

My problem is that I can hardly tell where I have already painted because the shades no longer differ. What can I do if I do not want to change or tint the color?

Thanks and best regards

The second coat should also be applied over the entire surface. Or am I misunderstanding the question? Wet paint looks different from dry paint; two coats are common.

Hello,

"Wet paint looks different from dry paint."
That is exactly my problem. The difference is only very slight and only noticeable under certain lighting conditions.

Is there perhaps a trick involving a light source?

But we’re talking about a lit room, right?
If you consider that you work wet-on-wet with a roller and can cover 10 square meters in about 10 minutes on an open surface with a smooth motion, I don’t see your problem. You work with ample paint, not sparingly, and apply it in two directions.
Then, working within an imagined grid of about two roller widths from left to right or vice versa.

So: even if you can’t see the edges, your brain should be able to remember where the roller has just been within that short time, considering a room height of about 2.5 meters (8 feet)!

Have you already started? Are you imagining this problem? Do you stop and start often?

Use a spotlight and direct grazing light onto the wall—that will definitely help you.
