Hello professionals,

Can I do it this way? Or is there a reason not to?...

I built a masonry garage last year. The interior is finished. This year, I want to do the exterior facade. I don’t need to insulate it.

My plan for the facade is as follows (I’ve heard about this method):
Attach 2cm (0.8 inch) Styrodur (extruded polystyrene foam) boards directly to the masonry using special insulation anchors.

Basically, the entire exterior will be covered with these Styrodur boards. Once they are attached, I will apply a base coat with fiberglass mesh embedded in it. After that, the final decorative render, such as a high-quality render or Capatect textured render, will be applied.

My specific concern is about anchoring the boards to the bricks. Is this a good idea? Or would it be better to skip the boards and instead apply a rough render directly?

I would appreciate many reports of experience and advice.

Best regards,
Jürg

Hello,

I would skip insulation for the garage. What would be the point of it?

Just apply exterior plaster and that’s it.

Exactly for this reason: I don’t need to apply plaster. No base coat. No finish coat.
Only the panels (the thinnest ones available, 2cm (0.8 inches), because no insulation is needed). These will then be filled and leveled with a glass fiber mesh, as I already mentioned, and then the decorative plaster will be applied on top.

This is cost-effective and practical. Since no base coat or finish coat is needed... above all, I can do it myself and save a lot of labor time that I would otherwise have to pay for. The textured plaster will be applied by a mason anyway.

Keep going, so we can know what else you are planning to do wrong!
