Frequently Asked Questions
- What is rendering?
To render is to coat the exterior or interior surfaces with a layer of cement based, acrylic modified render coating. Rendering is essential for all jobs as it straightens the wall and gives a flat finish, ready for a texture or paint.
- What is a texture?
A texture is a sand based acrylic product that can be tinted to your choice of colour. There are a range of textures, each will give you a different finish. Application method depends on your chosen texture i.e. some textures are trowelled and some are rolled or brushed.
- How do I render my house without getting ripped off?
As a homeowner you should always seek qualified tradesmen. It is also in your best interest to get more than one quote. Make sure the quotes use the same specifications. Some details you should ask to be included in your quote are:
- Are angles being used for the corners? What type of angles are they?
- Is a specified system recommended?
- How many coats are being applied?
- Make sure they using the same brand throughout the job? (more then one brand will impact warranties)
- Are you getting a warranty for materials as well as labour?
- Make sure the tradesman is licensed.
- How hard is it to render my house? Can I do it myself?
To become a Renderer requires a four year apprenticeship, so to pick up a hawk and trowel and attempt it yourself may be a challenge. However, there are products on the market such as Concote (an acrylic bagging system) which make it easier for home renovators to do it themselves.
- Can I render over fibro or painted bricks?
Yes. There are a range of products which can be applied over fibro, blueboard and painted brick.
- How long should it take?
Every job is different but generally rendering a front façade could take about a week and the whole house perhaps a month. With acrylic products a job should be done in a third of the time compared to sand and cement.
- How long do I have to wait before I can paint or texture the render?
Curing time for traditional sand and cement is 28 days, whereas acrylic renders which are supplied at RTP have a curing time of 48 hours. This can be a huge cost saving especially if scaffolding is involved.
- Can I get a warranty?
Yes. Check with your tradesman for a workmanship guarantee. Manufacturers supply individual job specific warranties.
- How long does acrylic render last?
With a full specified system you can achieve up to a 10 year warranty.
- Can I repair cracked or delaminated render?
Yes you can. To fix a hairline crack a textured or membrane paint will bridge over the crack. However usually when there is a crack there will also be delamination. Delamination can be detected by tapping the area on the wall and it sounds hollow. This is a problem that needs specific attention. To fix, cut out the delaminated render with an angle grinder then gently remove loose render and patch with acrylic modified render.
- Where can I see the finished product?
We have a showroom and finished walls with various textures at our warehouse at 2/28 Oramzi Road Girraween.
- Which Renderer do I use?
We can provide a list of Renderers that operate in your area, always ask to see examples of there work and there qualifications.
- How do I maintain my house once it is rendered and/or textured?
The only maintenance required would be to keep the surface clean. This is generally done with a low water pressure cleaner.
