Why would you do this?

As TheDec has pointed out the problem is due to the initial cutting in and the amount of paint used and failure to feather out.I have experienced this problem myself.

I would always roll after cutting in and ensure less pressure is applied towards the edges.

I struggle to grasp the madness of you posts sometimes.

obviously you are a pro with a roller unlike some other diyers. the amount of jobs i've been to when other people have left horrible track marks at the edge is unbelievable. would be nice to see them soften them off before the paint dries.

i pride myself on the standard of my work and have a steady number of return customers that keep me busy in my free time with no complaints.

I went to college and its true actually. They were quite happy to let you spend all day wet abrading a door! Always taught to cut in first though. Sometimes if the cutting in creates a picture frame effect i just roll a third coat and agree with dec that if you feather it out it eliminates the problem.

The other thing is that people roll into the cutting in with a fully charged roller so they effectively apply a third full coat to the areas that have been cut in. I always roll up to the cutting in and then when the roller is low on paint just go slightly into the cutting in and then back roll and lay off with light pressure in one direction.

Funny thing though, i see Dulux have got the dog on tv at the mo and some birds rolling a wall in red, its cut in where she's been but not where she's rolling to, kinda gives the impression to the have a go diyers thats how its done, typical dulux i guess, missing the finer details as usual, reckon they'll be history if they don't sort they're act out fast

I have noticed that my lines are not actual the cutting in problems as I first thought. My dad came around last night and pointed out that the marks seem to be all where the metal strips are applied by the builders under the plastering on every corner of the room and around the bay window where I presume the metal strips are also applied, so not just where I used a brush.

The house I have moved to is only a year old and the plaster the builders applied is real thin, do you think my dad is correct and any solutions, if this is the case I am going to have the same problem in every room I try and paint.

You are talking of the external angles aren't you, if so these are corner beads, just apply a thinned oil based undercoat over them then when dry apply your emulsion.

You say that you couldn't get tight enough into the corners so I presume the problem is also at the internal angles.
As the house is only a year or so old, it could well be that the plasterboards have been taped and filled rather than skimmed and it is this tape that is causing the problems.

Very good point that could well be the problem.

Well it's certainly possibility now that we've had a bit more info.

It could be that the existing paint was the typical new build Contract emulsion and jigger11 has now applied a vinyl (especially silk) over it which is causing the tape to be more noticeable.

TheDec · 7 Oct 2011

Yes indeed a very likely scenario.

Ok thanks for the info I think I will try a primer like you have said and see what it looks like it seems to be showing on all the positions where the metal strips would be applied for example the sides of the window and top of the window I also have a bay window with several pillars around the bay window and these all have the lines showing even though I didn't use a brush on these parts , the corners of the rooms are only slight where I used a brush and then went in with the roller which I could live with but its all the other parts that look so bad, at first I just thought it was because I used a brush but when my dad pointed it out I realized I hadn't even used a brush on some of the parts that were showing the lines!

Thanks for the advice. do I need to lightly sand the lines down before I apply the primer and also do I only need to use the primer on the effected area?

TheDec · 8 Oct 2011

There shouldn't be a need to sand and just apply the thinned undercoat to the affected areas.
