Plaster exterior garage wall made of Leca?
Page 1 of 2
I am building a garage and one of the walls will be backfilled about 2/3. We have built up the wall with 190mm Leca.
Do you need to plaster the outside with about 10mm plaster if you will have 100mm pordrain boards and fabric, or is it enough to apply a thin layer of mortar about 2mm?
The part of the wall that will be visible will be lathed and clad with wood. The other walls will be built with a wood frame.
Hope there is someone who can provide some guidance.
Best regards,
//Johan

Should one apply a red primer on the inside as well, or just plaster? I will not be putting up boards on the inside but will use the plaster as the finished wall.
Was mostly thinking about the outside if you can apply a thin layer of B-bruk before the pordrainskivan is to be installed. or does rödgrund have any other advantages if you're not going to plaster more on the wall.
The red sealant prevents air and water infiltration but not vapor, so water doesn't penetrate the wall, but moisture within the wall can dry out to the Pordrän board. An extra plaster layer does not improve it between the Leca and Pordrän board. On walls to be plastered with regular plaster and not with Weber's EF series or Finja's equivalent, apply a 3mm red sealant to even out the wall's absorption to avoid the grid pattern on the wall when it's humid outside. The Leca blocks and mortar absorb differently, and if you don't apply a sealant, you will see the mortar through the plaster as it absorbs moisture more than the blocks...

Perfect, then it will be red oxide on both sides. Do you mix it like "välling" and apply with a brush?
Thanks for the good answer.
Thanks for the good answer.
What are the application alternatives?
Booked a funnel gun at Cramo so now it's just a matter of going ahead. Which nozzle fits best for rödgrund?
Can you apply the plaster on the inside wall with a funnel gun as well? Or how do you do it there?

Okay.
If you have things around that you don't want to get primer on, they should be covered with plastic like environmental foil/covering foil. Not that thin painter's plastic but the thicker one on a large roll. Windows, sheets, etc., if any of these are installed, should also be covered with plastic. Tape with black-yellow warning tape, it doesn't leave marks on glass/sheet metal, etc.
If needed, any acquaintance can help hold up a masonite board to protect adjacent things like cars in the neighbor's driveway, etc. Look around often and assess where it lands when you reach the corner of the house/window opening, etc.
Inside, it's fine to apply a layer of primer for grounding, but not fill or so. The funnel spray is only used for priming and texture in normal cases.
The nozzle isn't so crucial since you're only aiming to apply material and not create any specific texture. One of the larger ones, I would guess, works great, but it also depends on which type of funnel spray you're renting.
Make sure not to have the airflow fully open where you adjust on the connection to the funnel spray. It should slightly splutter (hard to explain the sound), and then you can turn it up a bit more. From there, adjust according to how you find it works and how you are working.
Go for it!

Should you smooth out the red primer with a broom after spraying it on, or is it enough to just spray it and then let it cure?
