Thread: External rendering - Perth

Im hesitant to say I can give you a price as things are very busy and you could wait 6 months but if you are interested I can come up and give you a quote

Its hard to tell without looking at the job ie. if you need to cover paving or access corbels height cleaning windows. Established areas always requires more work than a new dwelling.
You can sometimes double the price for established places.
PLants near the building may need to be pulled back and service pipes, downpipes plumbing airconditioners all need to be taken into consideration.
Two coat always is better fo a better finish even if you paint and better to paint than use a coloured render.

I have been doing the ring around as I am looking for someone to come and render our existing house and extension.
Looks like the "going rate" for
AcraTex is approx $55 - $70 per m2 (can be tinted to any colour)
Sand render is $25 per m2
White set plaster $22 per m2

If anyone can recommend a good plasterer (North of the River) it would be very much appreciated.

Hi everyone!

Thanks for the replies.

rmartens, we were informed by one of the guys that gave us the quote that we can only use coloured render as salt is starting to appear on our bricks and painting over render won't allow it to breathe. Apparently it's happening all over Perth at the moment. There aren't any obstructions like plants or anything, all we have is 2 big windows in the front, small meter box to the side, front door, small bedroom window, single garage and a wall that separates the two duplexes from the garage. Same applies to the other side.

Unfortunately we can't wait 6 months as we are planning to sell soon and want this done ASAP. But thanks for offering.

Since starting this thread, the first guy who gave us the quote rang us out of the blue and reduced both his quotes to $4250 and $5750 for grey and coloured render respectively without us even asking. Second quote from the other company is still cheaper though. Btw, I forgot to mention in the first post but both companies are providing 2 coats.

perthreno, I've sent you a PM.

You can use a mineral silicate based paint, that will allow the brocks to breathe. Porters Paints make it, and Kiem (might be spelt Keim) Mineral Paints also make it.Where is the salt coming from??? Are you near the coast? I am interested in why this is happening, as I question the durability of painted bricks / render in the long term myself (have seen q few jobs where it is flaking / peeling - might be to do with moisture).frog_hopper

frog_hopper, we live NOR, 8km straightline from the coast. We have lived in our place for eight years and it has only been this past year that we have noticed something white appearing on our dark coloured bricks in a few places. Nothing major, just a few bits here and there. We didn't really know what it was until the guy who gave us the quote said that it was salt.

Hi all

We are in Perth, Bullcreek miles from the beach, our house is 3yrs old and we are now seeing white stuff appearing on our cream bricks?

Is this salt, I thought maybe lime or such from the mortar?

Anyone got any ideas what this is?

Wow! Only 3 years old? Ours is twenty-something years old. When I touch our white patches, it doesn't feel like salt... more chalky like.

We're planning to build again soon so hope it doesn't happen to our new house.

It might be Efloressence - look it up on the web.

Hi Kryptic

Ours is the same ??? I do not think it is a bother tho.

Celeste

Its interesting about effloressence. Salts coming out of the bricks.
Its common on new buildings.
Frog_hopper is correct. There are paints you can get that allow your walls to breathe.
Doing texture coats is not the only option but they are a good product and are very flexible.
The only thing you are stuck with the colour. With paints you can repaint over a period of time.
But I have seen places that were texture coated and have been painted.Attachment 60861
I have inserted a photo of a two coat render I did in /august this year as there was some rain the second coat was water proofed and so the water ran off the render and did not absorb as well into the render.

The salt must have been present in the building material or the water that is added to the mortar or concrete.

Or it can appear if the dampcourse is breached as it rises up from the ground.

It will eventually disappear, many years from now....
