Plastering for Beginners

[Galten]

Hi,

I'm planning to plaster my garage and have bought "Fiberputs B" from Finja and various tools. I've also watched numerous YouTube videos.

But there are some things I'm not clear on, like how long to wait before starting with the plastering float? And what to do if I can't finish and need to stop?

And if there are other tricks I should be aware of, of course!

Hello,

I'm planning to plaster my garage and have bought "Fiberputs B" from Finja and various equipment. Also, I've watched a lot of YouTube clips.

But I'm unsure about a few things, like how long to wait before starting with the float? And what to do if you can't finish and have to stop?

And, of course, if there are other tricks I should know!

I unfortunately can't give you any advice, but I've tried it myself and found that the YT clips are quite optimistic. I think it takes a lot of practice to get it right. But I hope you have more talent than I do.

Took on the project today, feel it went better than expected. Spread the plaster and then used a felt trowel on it. The wall isn't completely smooth but I think it doesn't matter in a garage

Did you use trim to make it even and smooth or are you just throwing it on?

Did you use strips to get it evenly thick and smooth, or are you just throwing it on?

I just threw it on and tried to get it somewhat even by eyeballing it.

Nicely done, it looks great!

I have a feeling that you should wait at least 14 days on newly plastered surfaces before painting.

I have in mind that you should wait at least 14 days on freshly plastered surfaces before painting.

2-3 months one should wait before painting as a lot of moisture needs to get out.

That's good info, I was planning to paint it white later.

Is it silicate paint that's needed then?

There are different schools of thought on that issue. Some paint manufacturers argue that plastic paint is good because it makes it obvious if you have moisture problems….
I have used silicate in the basement.

You can also find out with silicate paint, as there will be efflorescence from the mortar if it's masonry.

Regarding the actual shade, I've gotten the impression that you need silicate paint to achieve that "sparkling" white. That regular wall paint never quite gets as white.

But it's possible that this is more of a prejudice than a fact on my part.

Are you sure about that? I think silicate paint is relatively matte.

I am not sure 👍

We have some plastered interior walls with plastic paint in the basement, and there has generally been paint peeling and plaster breaking down into "dust"/gravel at the bottom by the floor - probably due to moisture coming through the slab. (older house without capillary-breaking gravel or insulation underneath). On the exterior walls, there is wood wool that has been plastered over, and there is not the same moisture problem except in the corners where downspouts have gone down too close to the facade...

The walls that I have repainted with silicate paint (primer and paint) do not have this problem, so I believe that silicate paint is more permeable to moisture, resulting in no peeling or bubbles there. I would never paint with acrylic paint on plaster today.

A really nasty and rainy day today. Went out to the garage and was met by this 🤔
The wall had an even color yesterday
Seems like it's raining through the wall?
