Rust stains with Crevole bricks 11Apr 11, 2016 8:23 am xyz snufl Hi xyz Our bricks were laid just over 2 years ago . Thank you for exhaustive set of photos. Also I noticed that your mortar technique was probably flash. Am I right? Probably this is the first time we see "flash", all other buildings were "raked". Yes, ours are a flush joint. The reason is that our house is very exposed to salt laden wind. By keeping the wall as flush as possible it gives the salt a chance to wash away rather than sitting in the crevices of a raked joint. So it is to minimise the risk of salt damage to the mortar. The Crevole is an exposure grade brick, so I think the quality would have to be high to cope with extreme conditions. I've had a good look at your photos of the Bondi units and I have to say our actual bricks look as good as the ones used there, I really had to search around the house yesterday to find the few stained ones I photographed. The raked joint does accentuate the lovely straight edges of the brick, but we went with practicality. We still get lovely straight edges and corners to the house which I like. The 3 Holes - Yes, our sample brick and all the bricks laid had 3 holes. I believe that, because of the light clay colour, they come from Queensland. Re: ? Rust stains with Crevole bricks 12Apr 11, 2016 7:47 pm TomCat We built our house with PGH Bianca. They are similar but I think they are in SA only. They too are creamy/white slurry brick but have a light pinky/cream clay base. All bricks will chip so we need to consider that when choosing ... Doesn't really bother me, I reckon they'll hold up well enough over the years. If I get too many chips that do start to stand out, I'll mix up a white watery paint wash and brush over That's actually why snufl have chosen PGH Crevole and that is why we are planing to use it. It is a premium brick and it coloured deeply inside. Agree "all the bricks chip", but this will remain white under the chip, contrary to PGH Frost which has a coloured veneer over the core. Of course some mold can grow here, some dirt can gather... but... It is pity that in SA there is not PGH Crevole. It should suit SA climate exceptionally well. As I can see here PGH Bianca is something like PGH Frost, the same thin coloured layer over the core: Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ may be, sorry, even worse (it terms of whiteness) than PGH Frost. Building Casaview Denison 30 https://fortdenison.wordpress.com/about Re: ? Rust stains with Crevole bricks 13Apr 11, 2016 8:03 pm TomCat Could the differences with those bricks be because they are from different states? Did you do your Gumtree search for your state only? Australia wide, I would even say world-wide, because there almost no information from independent sources (non-PGH) about that bricks so I google the widest possible way and found only little. TomCat Possible they've been mis-labelled by seller too. The probability of this enrages me. I think PGH could at least always produce this brick on the same equipment using the same core hole pattern. They know it sometimes easy to mix up Crevole and Frost, why not create some distinguishable looks for these 2 varieties? How can I be sure that piles of not cheap bricks they will deliver to my lot are of right sort? That makes me saaaaad panda... Building Casaview Denison 30 https://fortdenison.wordpress.com/about Re: ? Rust stains with Crevole bricks 14Apr 11, 2016 8:32 pm snufl I have never seen anything like this on our bricks. Looking at the photo even the mortar looks grey in places. To me this looks like dirt or mould on the surface rather than defective bricks? the camera didn't catch it well... but to my naked eye it looked like scam/cinder (similar to that you can see on some photos above not on face of the brick, but on top and bottom)... It seemed to me that stains was not result of damp patches/leaking... And too regular I think for mold. Vice verse as if brick has been drawn out of a kiln incorrectly or has been incorrectly extruded from. I hope I wrong Building Casaview Denison 30 https://fortdenison.wordpress.com/about Re: ?

The Crevole is an exposure grade brick, so I think the quality would have to be high to cope with extreme conditions. Even with flush it looks great, we also plan to flush but mostly to avoid mold and dirt accumulation on mortar. After all in Sydney we all have just 3 metres to neighbours nowadays, a half of the house will be shadowed. snufl The 3 Holes - Yes, our sample brick and all the bricks laid had 3 holes. I believe that, because of the light clay colour, they come from Queensland. Alas, looks like number of holes is not a good indicator of the brick sort at all. And this is what we fetched from PGH Display Centre in November: Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ I dare say left is PGH Frost and right is PGH Crevole, but cannot say definitely because they were mixed together either by customers or by the personnel... So they could be: -- with 3 holes -- with 10 holes -- with 9 holes (bigger oblong hole in the middle) Building Casaview Denison 30 https://fortdenison.wordpress.com/about Re: ? Rust stains with Crevole bricks 16Apr 21, 2016 11:39 pm And this is example of what could happen with Crevole, when a brickwork is not covered/not under eave. Water spilling from balcony leaves dump patches which become permanent stains with time. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Also I found that PGH recommends: "It is recommended that an ironed or flush mortar joint is used when Frost is laid." Looks like this is so because black scum that PGH Frost has on the top and bottom. If it is raked, it will be visible. Currently decided to stick with PGH Crevole (because other options we preferred PGH Sandstock range are even more expensive). In turn the builder promised to do everything to lay and then clean this brick the correct way. Building Casaview Denison 30 https://fortdenison.wordpress.com/about Re: ?
