Sand Finish Render Overview:
Sand Finish Rendering was the most popular choice of Perth Builders up until 5-10 years ago when Acrylic Texture coating came in as an option.
When you drive around and see rendered homes and walls, 90% of the time you’ll be looking at Sand Finish.
Now days, Sand Finish Render is still a popular option for a very small percentage of builder of Perth Builders, mainly because once painted, Sand Finish render costs about 10-20% less then Acrylic Texture Coating.
I find that about half of my customers opt for Sand Finish Render so they can paint the walls themselves and save some money on hiring a painter.
There’s nothing wrong with Sand Finish Render as long as it’s done correctly, cured and there is enough time left to dry before painting.
- Mix 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”.
- Now, using a special water spray guy that produces a fine mist, we wet the walls.
- Then, we “float” the walls with a large flat “float” tool that further flattens the walls and creates a more uniform surface.
- We then wet the walls again and finish off with a sponge to give the “Sand Finish” look.
- The walls are now ready for painting.
Sand Finish Render mix is made from Sand, Cement and Lime. This ratio is mixed exactly at 6 part sand, 1 part cement, 0.5 lime.
Where Plasterer’s commonly go wrong with Sand Finish:
- Use smaller quantities of cement and lime in the mix to save costs, resulting in weak render.
- Not using a specialist spray gun, wetting the walls too much which producing a rough finish.
- Not wetting the walls again at the end of the day to cure the render (so it doesn’t crack)
- Using old tools that produce a bad finish.
- leaving rough corners, too round or too square.
- “Free Hand Ruling”, instead of using straight edges and levels.
Advantages of Sand Finish Render:
- Cheaper the Acrylic Texture Coating.
- Able to save costs by DIY painting.
- No flexibility. If there is house movement cracks will show.
- Visible “V” joints. We have to cut fine lines where the render meets the eaves, windows and doors.
