Advice badly needed on through colour render

Hi,
I am building a large detached house in the South West. I have been working on it for 18 months and the end is all most in site. I have done most of the work myself, apart from the timber frame, the block work, electrics and plastering.
I got made redundant so I am pretty much working on it full time now but I have to live and pay a labourer so the lump of money I have left to finish the project is nearly all gone.

It is timber framed with a 7n block work skin. I didn't even know through colour render existed until well into the build. The architect said it would be cheaper to use standard concrete blocks and render it, rather than coloured fair faced concrete blocks which was what it was originally to be built in. i now know he obviously meant sand and cement render and paint.
I really would like to use a through colour render but I got the shock of my life when I got a quote from SAS Europe for Pro-rend. It is £9.50 a bag! The area to cover is 170 square metres and my plasterer / renderer said 15mm thickness. I was quoted just under £2500 inc VAT for materials and really need to get that down to £1500.
I am looking at other products like K-rend but there is not really a huge difference in price.

I need to know if I can use a sand and cement scratch or base coat at say 10mm then apply a top coat of a good polymer render at 7mm to scratch it back to an overall thickness of 15mm. I can't go any thicker because of the aluminium window sills which will only have the minimum protrusion of 30mm from the finished wall with 15mm.
I asked my plasterer if he could do this but he said he would still need to put a scratch coat of the through colour render on before the top coat so it would end up having to have 3 coats instead of 2 and cost me more in labour.

Most of my mates are in the building trade as I was in the early 80s but none of them know with absolute certainty whether it is possible or not as through colour render is more of a specialist thing.
I think 10mm of sand and cement with mesh embedded, then a special primer/bonding agent sprayed on, then the 7mm top coat of K-rend roughed back to 5mm. I could apply the primer my self and stick to the original labour only quote of £12.50 a metre for 2 coats?

Can anybody give me any advice please. I don't want to compromise the integrity or the weather proofing but there must be a more economical way of doing it, even if it is more labour intensive for myself. My time isn't really costing me anything at the moment, except for my sanity...

It is a very modern shaped house with 2 barrel shaped roofs and I am one of those very dejected guys you have probably seen on Grand designs who is at the end of his tether and out of money. No I am not on the program. Didn't apply or want to be

All comments will really be well appreciated.

Cheers

Hi, Mc plaster,

Are there any other mono coats that are not so expensive besides Pro-rend and K-rend, that will look alright and not crack. I got a quote for Wetherby Epsirend WP today and that was £9.80 a bag! I'm going in the wrong direction price wise.
I found a different forum the other day where somebody had listed about 8 brands to use and not to use anything other than one of those products but I can't find it in my history.

thanks
 
9.80 a bag aint that bad, why do you want to scrimp on cost on the first thing youll see on your new house and will last a lifetime if done right.with it being a new build youll claim your vat back anyhow.
leave it alone for the time being and save up for it done right.
 
As the other guys have just do it in mono.SDI on South Marston ind est you can collect K-Rend for 7.30 +vat or delivered for 7.75
 
Thanks,

Just waiting for some samples from K-rend that I asked for last Friday, mainly to check out the colour. I want Ivory but want it very light as opposed to a creamier darker Ivory like some Ivories I have seen.
 
CPI is fairly cheap and popular in the South. Don't skimp on this stuff, done right it will good and last years. Minster might be worth a try for Weber and K-rend prices. You can also try Direct Building Supplies in Bradford 01274720905 and ask for Wayne. They deliver all over the UK. Good for beads too. If you look hard enough you will get the Weber & K Rend for about £8-8.20 a bag or less.
 
most mono averages around £9-£10 inc vat a bag. i think either do it properly or sand and cement it and paint. slightly cheaper innitially but longer and more maintainence longterm.

or as said, leave it 6 months, and do it next spring when u can afford it
 
Sorry build the pointing up flush with sand cement, tap it all with a stiff brush then paint ......tada mono
 
you not noticed the big advertising banner that comes up on the forum then and its just like that mono stuff

you asking here for something that looks good and something that wont crack but then not wanting to pay more than £7 per bag ? the answers are in the question

if you really want to install an anti crack system you will be raising your price way above the mono per bag rate pal
 
Why not mix your own? 5 parts white render sand from b


order aggregates 1 part 1-3 mm white dolomite from longrake spar 1 part white cement and 1 part lime. powder pigment is cheapest at harris stone. apply and scratch as normal it costs about 5 quid to fill a standard belle mixer and covers 3 meters most bagged renders contain polymer powder these polymers are either acrylic or styrene based both do the same job so add a pint of sbr to each mix

I just rang SPS to get a price on the Granicem and spoke to the company director in the end. He quoted me £10 a bag, what's that all about? Completely ruined my day!! I had a look at the technical specs and colour chart, ordered some samples and thought I had found the solution. Now it's back to the drawing board. That is a massive difference £6.50 to £10
 
Happy days :RpS_thumbup: Thanks Rigsby. I rang your mate and I got a cracking price on the K-rend.

By the way, I'm developing this place to sell on. My boy left school last year with hardly any GCSEs and obviously couldn't find work. I decided to to get back into the building game as a developer this time, not a chippy and give him a job to keep him out of trouble and teach him some skills. Took this project on and it was a bit too ambitious really after 20 years out of the trade but we'll get there in the end - somehow:huh:. It was a building plot with full planning permission to build a modern, barrel roofed Eco house and the plans had already been passed but it went up for auction before work started so I had a bid and won it. Will live in it for a year though for tax reasons and while I find and build the next project.

Thanks for the helpful comments and advice to all.
