Choosing points
- Best for walls, floors, exterior details, and shop interiors where a rough inorganic base feel is wanted.
- Trowel marks and curing variation are normal.
- Raw mortar stains and dusts more easily than sealed or painted surfaces.
- Hairline cracks often appear around corners, openings, and substrate movement.
How it ages
- Durable when bonded and cured well, but cracks, efflorescence, and water staining are common in exposed areas.
What to avoid
- Do not use mortar as a waterproofing layer or movement joint filler; it cracks and absorbs water.
