Acrylic Texture Coating entered the Perth market around 10-15 years ago and ever since has been gaining in popularity.
Most “high-end” or up-spec home builders will use Acrylic Texture coating for the rendering finish on their homes. This includes HomeGroupWA, Dale Alcock and Webb-Brown Neaves.
Texture coating usually comes pre-mixed in 15L buckets, It’s easy to describe texture coating as paint with granolas of large sand. Texture coating is tinted with the colour of your choice, so there is no need for painting. It is applied with a hawk and trowel over a flat cement rendered surface called “float” coat. Finished, the texture coating ends up being around 1-2mm thick.
There are a few suppliers or Acrylic Texture Coating in Wa, each with their own brands. The biggest texture coating supplier in WA is Dulux. Their Product is called “AcraTex”. Although Acratex is the most expensive of all the suppliers, we only use Acratex texture coatings because we believe it’s the best product and consistently produces good results.
I find that about 80% of my customers opt for Texture Coating instead of Sand Finish render for hard-waring flexible finish and the fact that they don’t have to paint.
- Sand, cement and lime is mixed in a cement mixer.
- Mix is applied to walls 12-14mm thickness with a hawk and trowel.
- Walls are “screeded” flat using straight aluminium lengths.
- Once the walls are flattened this is called “float coat”.
- We then wait 1 week for the “float coat” to dry. Usually we would have to wait 28 days but Dulux’s new “Green Render Sealer” cuts the drying time downtime down.
- Windows and doors are then re-taped for a superior finish.
- We then apply “Dulux Green Render Sealer” with a roller and paint brush to “Seal and Prime” the render, ready for texture coating.
- Texture coating is then applied by hawk and trowel, then lightly finished off with a finishing trowel.
- Dulux Acrashield is optional extra coating for added protection and better Waranty. I highly recommend this if you live very close to the coast. Most builders don’t apply this as standard.
Where Plasterer’s commonly go wrong with Texture Coating:
- Texture coating buckets are expensive. In an effort to save money, some plasterer’s apply the coating very thin, or water it down, which can lead to areas that are partially “see through”.
- Not waiting 28 days for the “float coat” to cure, or not using green render sealer. This can lead to peeling.
- Texture coating in direct sunlight or extreme heat can leave unsightly joins.
Advantages of Acrylic Texture Coating:
- Flexible coating with-stands hairline cracks.
- Amazing look.
- 40 times thicker then paint.
- Ability to cover steel lintels.
- No cut or “V” joins near doors, eaves or windows, leaving a perfect finish.
- Ends up costing around 10-20% more the Sand Finish Render and paint.
- Harder to make “touch ups” if a wall is damaged. Usually the entire wall needs re-coating, but this can also be application with paint.
