Dimples in multi finish

Am I the only one getting these...doesn't matter whether it's over PVA...yellow grit etc I often get dimples in the plaster (small raised dots) really annoying pretty much on every set. They show up in the paint and look terrible.

Anyone know what causes them? I never had an issue before.

They can be trowelled out with a hard trowel but that means hanging around for another half hour or more.

Then that’s what you have to do. Either suction or thickness you’re putting on.

Tbf you’ve answered your own question in the last sentence. Patience

Ok so I know what the issue is...the speedskim! Only started having this issue since I used the speedskim for flattening between coats and only over pregrit. Did a test last week 2 walls with and 2 walls without...the 2 walls that I used the speedskim on covered in dimples. So I've gone back to the Refina spat and the speedskim will go in the trash.

What grit you been using and over what background?

Never had dimples going over any surface with the speedskim tbf. The plastic blade doesn’t pull the moisture to the top like a steel blade, and if you’re going over grit then it’s prob going on a bit thicker, so it could be a timing issue.

You haven't even got a speedskim, you spakker
 
I bought a speedskim guys off YouTube said there a must with the sponge, got a hairdressers spray bottle also. I can't wait to get started

Thanks mate. Mostly over yellow grit...it only started a few months ago when I started using the speedskim...was driving me nuts for a while. I haven't changed my technique...thick first coat...flatten in with speedskim...tight second coat (new mix in same bucket not cleaned)....

Did I see you the other day in Bishopston? You were on scaffold no top on? Have you had your 2 front teeth knocked out?

I’d stick with the speedskim for a bit. Nothing dodgy about them IMO, just another tool. Works well for me and wouldn’t want to be without them on a job, but obviously could get by without. Funny really, as occasionally go into properties that I did a bit of plastering in years ago with just an 11” tyzack, and not much knowledge and no paraphernalia and it looks pretty good. Fast forward 10 yrs or more and different trowels and speed scams and yeah, still looks good but more confidence and hopefully know more about getting out the s**t when it goes a bit tits up on occasion. Can’t comment on the yellow grit. Mainly use the cementone green grit on anything that is potentially a bit dodgy, but now I usually mix a bit of SBR in with it which helps even it out over a varied background.

If you’re putting a thick first coat on, maybe needs a bit longer before second. Not trying to teach granny to suck eggs etc.

Im trying to convince my mate about them. Hes stuck in his ways, and takes time to try anything different. I said look its just a labour saving device thats all nothing to do with finishing. I said you need to work smarter at your age, he said you cheeky bastid we the same age. :ROFLMAO:

Your going over it to early and to much edge on the trowel

With the speedskim I go over pretty much straight away after laying on because you can with plastic...and in general I like to get it on fast and flatten in fast to make life easy...but these dimples are appearing as soon as I flatten in the first coat with the speedskim and it doesn't happen with the refina spat...

Hmmm maybe but I flatten in fast and then leave it until it's firmed right up before topping with second pass. Maybe I will try leaving it a bit longer before flattening and topping...see if it makes a difference X

Could well be the grit. I remember using green grit for the first few jobs years ago, thinking it would kill some of the suction on porous backgrounds, and it may do a bit, but it was a bit like going over bonding at the wrong time and getting blebs.
