Granol render is a decorative render with a coarse grooved effect, sometimes called a “tree-bark effect”, made up of short grooves running in random directions. It gives a facade a heavily textured, rustic appearance and can be overpainted to match a colour scheme.
Characteristics
- Coarse texture — short grooves in random directions create the bark-like finish
- Overpaintable — the surface takes masonry paint well
- Robust — the textured skin hides minor surface imperfections
- Drawback — the coarse relief is very difficult to smooth or level later if a flatter finish is wanted
Application
Where it is used
- External facades where a decorative, weather-resistant finish is required
- Refurbishment work, where the texture masks uneven or repaired substrates
Applying granol render
- Prepare and prime the substrate
- Apply the render to an even thickness
- Work the surface with a float or trowel to create the random grooved texture
- Allow to cure before overpainting
Because reworking the texture is awkward, it is worth agreeing the finish and colour before application.
