EThat article does not leave gaps in the choice of putty mortar for cracks.
Means 1.
Cracks in the wall of a well-embeds seal seams on acrylic base. His undoubted advantage is that it is unaffected by temperature changes. However, it is worth remembering that such a sealant "pulls" only opening up to 30 mmAnd is also effective when applied at temperatures below 5 degrees.
Means 2.
To fill the seams and joints more than 30 mm is better to use polyurethane foam. It is sold in cans or 750 to 700 ml, and is very economical.
Means 3.
If you need to seal the crack in a humid room (sauna, bath, toilet), I recommend to use silicone mastic - it is waterproof, rot and has good adhesion (sticking to any surfaces).
