Browse Forums Building Standards; Getting It Right! 1 Jan 31, 2014 6:15 pm Hi guys/gals. Just a quick noob question about rendering. Our builder has recently rendered part of our front facade. Now we requested acrylic render. However, when they where rendering they had a cement mixer and bags of cement. Now my question is when they use acrylic render, do they use regular cement with acrylic additive? Or it is pre mixed? How can I tell which one did they use (I.e acrylic or cement render? Thanks in advance. Re: how can you tell if builders used acrylic render vs ceme 2Jan 31, 2014 9:21 pm They may have used the cement in the base-coat. One way to tell acrylic render is to find a lump of it (the coloured top-coat) on the floor (you shouldn't have a problem finding some) and crumble/bend it. Acrylic feels a bit rubbery with sand/aggregate in it, cement render will just crumble into sand. Re: how can you tell if builders used acrylic render vs ceme 3Jan 31, 2014 9:54 pm Hey oncewerefurriers. Thanks for the info. Yeah it's still grey no colour (as you would with cement) at all and also no rubbery feel to the lumps. I believe this just confirms my hunch that they mistakenly used cement instead of acrylic. What's the best action to fix this? Should I request to get a full refund of the rendering or just the difference in cost between acrylic and cement? Feeling disappointed since our builder is the one who suggested to use acrylic render because cement is prone to cracking. Re: how can you tell if builders used acrylic render vs ceme 4Feb 01, 2014 4:18 am We have acrylic render but the first initial bit of render is just grey with no colour and did seem just like normal cement. When the next layer was put on it was the acrylic render and we could find rubbery clumps on the ground. I'd say you just have the first layer Re: how can you tell if builders used acrylic render vs ceme 5Feb 01, 2014 8:53 pm I agree, think you have just seen the first layer. The acrylic render our builder used is Dulux acratex and it comes pre-mixed. Keeping that in mind, we just had our render done and it wasn't as nice a job as the display home (we chose the same product same colour). So each renderer trowels it on differently. The endges etc were fine, but the side of the house looks like inconsistncy of colour, streaks etc. Bad finsih we were disapppionted luckily our builder agreed to coat another layer on the worst side. So keep an eye out on the finish. Re: how can you tell if builders used acrylic render vs ceme 6Feb 04, 2014 4:26 pm Just an update. Spoke to our site supervisor and he said that the finish of the acrylic will be poorer than cement is this true or pure BS? Re: how can you tell if builders used acrylic render vs ceme 7Feb 04, 2014 8:04 pm In what way is is poorer? It may be rougher depending on the texture. Coventry Coarse is.... well quite coarse, there are finer textures. A fine sand-finish will be about the same roughness as the basecoat. Maybe he means the texture will be rougher. Acrylic looks like paint with aggregate (of some description) in it. If applied properly, you shouldn't see any of the basecoat through it. Re: how can you tell if builders used acrylic render vs ceme 9Feb 04, 2014 11:20 pm Honestly, I don't mind whether it is smooth, rough, or swirly as long as it is uniform. My main concern is cracking. So does acrylic prevents cracking or its less prone to get cracks vs cement? Re: how can you tell if builders used acrylic render vs ceme 11Apr 10, 2014 10:49 pm Hi Guys as I understand here there is been a lot of comments talking about texture coating and not acrylic render. it is very common to use traditional cement render and them over coat it with a flexible and crack bridging coloured texture coating as dulux acratex or other brand Acrylic render is usually applied over a variety of substrates and is not flexible you can find info at www.acrylicrender.com.au cheers! Fabio Re: how can you tell if builders used acrylic render vs ceme 12Aug 07, 2014 8:24 am Ok, I think I have the same problem as Spencer did. I went to the building site today, knowing that it was time to put the render on, to see a big pile of sand rock up. I'm now freaked out because I paid $3,500 more for acrylic render. I was very happy to pay this to have a superior product that wouldn't crack. Now I'm concerned. Is it normal to put a cement undercoat? Is this used to "smooth" the wall before actually applying the acrylic. Would love some input on whether I'm getting the best outcome.

Just an update with my render. The builder thought that I wouldn't like the acrylic finish on the render so they went ahead with cement even though I requested acrylic. They offered to re coat the render with acrylic and was told that it will not make a difference on the susceptibility of the render from cracking over time. Our build is taking way too long we just reached lock up after a year since we started. So I just opted to get a refund on the difference rather than delay it. So make sure you confirm it with your builder asap rather than leaving it late which I did. Re: how can you tell if builders used acrylic render vs ceme 14Aug 07, 2014 9:27 am The joys of building with a volume builder. Re: how can you tell if builders used acrylic render vs ceme 15Aug 07, 2014 9:47 am Its funny I think (funny as is BS) that you have to confirm something that has been requested and confirmed by yourself. I presume this was written in the contract. I would be also asking for the difference between what you were charged originally for acrylic render and the material cost only of the cement render as they should not have changed without telling you. Also I would be saying that includes your "variation" fee as well. Isn't if crazy, we want to change anything and we have to pay a variation fee however if the builder changes something all you get is the sorry and generally some lame excuse. There must be a reason acrylic render costs more than cement render and I do not think the finish is poorer. There are plusses and minuses of both methods. Re: how can you tell if builders used acrylic render vs ceme 16Aug 07, 2014 5:38 pm I agree with you aussiemark. I honestly have no idea in any building works but I know what BS looks like. It's definitely a mistake made by the builder. They're just trying to justify their mistake. I We have more issues with our builder but manly miscommunication issues and build management and they're sooooooooooooooooooo slow. Had a building inspector (Howard ryan) insect pre gyprock and found little minor defects. Been lucky so far but so slow. Still counting ourselves lucky though but it's now testing our patients. Next week will be 4 weeks past our end contract date. Bathroom tiling just finished. Don't know what to do or who to speak to and try and get advice to get the builders pull their fingers out and finish or try to get some compensation other than liquidated damages. Re: how can you tell if builders used acrylic render vs ceme 17Aug 07, 2014 10:29 pm To be honest I would rather see things done right to a high standard and finish a little later than rushed and done poorly or incorrectly. I would ask your building inspector about compensation but I would think you would need to establish that you have lost over and above the liquidated damages amount. Re: how can you tell if builders used acrylic render vs ceme 18Aug 09, 2014 6:49 am I had discussed the acrylic render with our Supervisor, so they are clear that is what is required. In fact, he brought it up. I just wasn't expecting sand to rock up. That had me worried. I know how you feel, Spencer. Our build is also progressing slow-ish, but still within formal dates. The quality of the work has been quite good so far. The one major issues was when a welder set the insulation on fire. My husband was actually watching at the time. Anyway, they had to take down part of the brick wall to replace the sheet of insulation.

Then you could see if the thickness of the render was up to standard as well plus done correctly at articulation joints. Often it is too thinly applied in my experience, Leonardo_23 Re: how can you tell if builders used acrylic render vs ceme 20Jun 08, 2016 4:45 pm Acrylic render is WAY BETTER than just normal render. It lasts forever and you never have to re- paint your house!! EVER!!! Will never crack! Hi Alex, Thanks for the reply again. I had a chat with the builder, he said he will use primer, then hydrotec which comes with colour and sealer as well.
