Plaster ?

Tmurf

Hi I have 2 internal walls built a few years with normal skim finish where the actual finish has a lot of lines or streaks on it that can only be seen when the sun shine on it or you look at it from an angle.
They don't feel very rough but it is extremely annoying when you do see it.
Just want some advise before I get onto the plaster.
Also wondering if the walls can be re-skimmed, or would the plaster have to come off ?

Skim cost properly just tried out too fast due to heat from sun shining on wall. Wallpaper the wall and you will be grand or give it a couple of coats of good quality paint.

all depends

plasterer may not have troweled/finished the coats correctly, eg 2 trowels when it may have needed 4,

is it kinda rought to the touch or ridged if it was correctly finished it would be smooth

it can be reskimmed but it is a messy enought job,

OP has stated that it doesn't feel rough to touch so good chance it was a reasonable standard of workmanship. If it was poor workmanship it would be evident elsewhere too

thought op stated "They don't feel very rough"

lines etc can either be water markes or if a plasterer didn't trowel in correctly eg 1st cat gone ff before 2nd coat applied

i'm assuming it may be a plasterboard wall eg internal although it could be block or drylined even still 1st coat on board should always be wet trowled before applying 2nd coat thus no lines etc



difficult for a lay person to know what is a good quality finish or not,

from what i've seen of some workmanship in last 10 years here "all Trades" the majority would not have been a standard i would have accepted

if op can post a pic it may be easier to determine the defects

Sorry to be more clear.
This marking is on a few walls but 2 are more noticable.
Personally it looks to be a case of workmanship...or his tools or as markbld65 said - it may have needed more trowelling or finishing.

And archtech, The walls have been painted a few times and still comes through.
I would prefer to get a job done propperly, not get it repainted or wallpapered over to cover up someone's shoddy work.

Just wondering if the walls could be reskimmed since plaster has been on a good while and painted.
Thanks

walls can be reskimmed re below

1.keyed/adhesive/re-skim, a skilled plasterer can do this

2.it can also be amed eg a solution much like filler this if applied correctly may solve the issue

3. may also be able to sand out and fill where lines are

you could try a good painter he may have some ideas re point 3

i've seen some terrible workmanship over the years incl one coat wonders and no trowling

any chance you could get a few pics up ?
