Pressure washed this roof last week now the customer has rung up and wants it sealed, not painted, no colour, clear sealed like a drive so.....
What are the options, I'd like water based and to be able to spray it on, but what is airless spraying? Can I use something like the battery powered cuprinol sprayer ??
Suggestions please

Darran,
Kev Martin does a penetrating sealer that can be sprayed, its clear and can be used on drives etc.. But he would need to confirm is use on a roof. I can't see why it wouldn't be suitable.
Otherwise, search for the companies that sell the roof coatings, as i am sure they would do a clear one.
You can hire airless sprayers from most hire companies, but you will need to be carefull what has been used in them before. An airless sprayer would be easier and a lot faster as you wouldnt need to keep filling up the spraypack.

Miracle 511 H20 Impregnator Water Based or Better still Miracle 511 Original Impregnator. Don't be put off by the price both easy to apply and you should get enough out of either to do 2 possibly 3 roofs

Put either of those products on that roof with an airless sprayer and you will need a mortgage.
Go for a water based acrylic with a fairly high solids content . http://www.creative-impressions.com/gemseal-concrete-sealer.html

Kevin, do you dilute the 511 ?

No you use it straight from the tin.

Blimey, 4 ltrs can cover at least 90 m2 neat, how the hell do you get it to cover that amount of area??

4 litres will do at least 200m2 with that type of roof

Ok applying by what method Kevin ??

What gear do you have to get up there? You going to use a boom, scaffold etc

I've just been using 511 enrich & seal on a Limestone patio from hell!! 44 sq mts, and all I can say is the product goes along way, only used 2lts max 2 coats, so the products are good. Could be different for a roof though, but I'm sure Kevin will advise.

It might be called Miracle ...but he is going to need one.
Smudger be very careful in what product you use....this is not a fine grain sand or lime stone . It very porous rough aggregate . It will absorb anything you put near like a hooker on coke.
An airless spray gun will empty the 4 ltr tub in a matter of minutes.
Kevin when did you last seal a knackered concrete tile roof with this product?
Whilst I have every respect for you and your products ...I think you are offering the wrong advice....but I have also being wrong on many occasions .

Yep ...Teflon would work.(
Still think high solids waterbased acrylic is better...in this instance.

Which is it?
He has approx 150sqm of roof there...4 litres or 2/3 roofs 300/450sqm ..4 litres?

Thread has now gone sideways, smart seal mentioned. Give up, go to bed y'all.
-
Smartseal is supplied by pic seal so is not bad stuff as far as sealers go
-
Really interested in your stuff Kevin, I like the fact that this penetrates into the surface rather than sits on top as the customer wants the 'natural' look retained.
My worry/concern is getting this coverage and how to do it.
Personally I don't want to brush it on, long winded and faffy, rollers are ok but surely 1 ltr can't be spread out that far ????
I would like to spray, but never used airless sprayer but have used the pump sprayers and battery powered sprayers for fencing

Spraying it on will be fine in this situation but obviously you would not get the maximum coverage out of it applying it in this way
Miracle 511 H20 Plus 3.785L (US GALLON) will cover 46-279m2/Coat
Miracle 511 Porous Plus 3.785L (US GALLON) will cover 46-186m2/Coat
Miracle 511 Impregnator 3.785L (US GALLON) will cover 46-370m2/Coat
This will obviously depend on the porosity of the tile

Thanks Tony
Hopefully the customer will give me a yes

So we have gone from 4 litres doing 2/3 roofs to 16 litres to do this one roof...Smudger be careful.
From my experience (which is sadly lacking compared to roof Tony and Kevin) you will get around 4/5 m per litre on this type of substrate.
Get yourself a tile and a sample of the product from Kev and test it yourself.
Kevin and Tony are reading labels and guessing.

I am a bit too experienced to read labels and guess as is my son. If you understood the product you would be a little more "Au Fait" with it and you would understand that the product has been around for over 35 years a d there is a lot of Data available to us regarding coverage. Try the product first against whatever you are suggesting and then comment. It is you that is reading labels and guessing not the other way around.

Thanks again for the help

Ok assuming I am talking out of my sphincter .
Question 1 . Kevin/tony how would you suggest we apply this to the roof assuming at the worst we are aiming for 12 metres per litre (Tonys worst case scenario figures) disregarding your initial estimation of around 75 sqm per litre ?

Don't take my comments to heart I do value your imput but sometimes things can get very over complicated. We are currently grinding some rough cast concrete I will put a Litre in one of our sprayers next week and see how far it goes that should be 90% accurate I think as a comparison. What you need to remember is this stuff is made in California where you get sued for passing wind in the street so their coverage rates published are very very conservative. Even after 9 months of selling the stuff I am still trying to work out why it goes such a long way compared to Aqua Mix ??? ??? ???

Kevin that should be a good test... I will be genuinely interested in the results.
I don't doubt your product...but i have cleaned a few roofs and knackered concrete tiles are extremely porous. Thats why they are always covered in moss .

Was using pics for driveway sealers until they informed me that they actually supply smartseal with sealer and as there's one close to me I don't pay delivery which suits me fine. I also have a roof clean and sealing job which smartseal give me the lead for! What is worrying me is they offer a ten year guarantee with there roof sealers but the stuff just looks like water based rubbish like resiblock trade but charge a small fortune for it. Don't really want to get stung by this guarantee if the sealer doesn't last! Who would be liable if it didn't?

Sealed A LOT of slate with less than a gallon of miracle on Wednesday. It does go quite a long way, apprehensive at first but would use it again.

Miracle have just launched a new website
www.miraclesealants.com
Try it as it has a coverage calculator tool on it. Dies it in sq ft but just divide by 10 and you will be ok converting to M2. Ours should be up in a couple of weeks. www.miraclesealants.co.uk

Thanks Neil and Kevin
Neil how did you apply it ?
Darran

Slates different to a knackered tile roof....you can not compare. You cannot even compare application methods.
-
Yes I know Chris I wouldn't compare the two, IMO I wouldn't seal the roof unless they paid A LOT of money.
I applied it via roller in small sections and then went over with a microfibre cloth to wipe up the excess. Went back tonight to see how it looked after heavy rain and it looks good. Few small areas that have excess on which I'm not to happy with because I went over meticulously wiping up the excess so can't explain it.
It's on a few ridges on the tile, how can I remove these Kev?

No matter how well you think you removed it you left an excess so a quick spin over with a Rotary fitted with a soft to medium brush and some pH Neutral cleaner will sort it

Sorry, when you said slate, thought you meant slate roof :o
Darran

Cheers Kev, I usually apply sealer just by microfibre cloth all by hand and never get that problem, I think it's because I used roller. Quite annoying. Will it come off easy enough?

Any "spread rate results" yet?

Yes mate sorry about this and not getting back to you earlier. We sealed some really porous concrete with Miraclke 511 Impregnator and got a coverage of around 16-18M2 per litre so 65-73ish per US Gallon.
I would calculate an average roof on a 3 Bedroom in this country at around 240M2 ish so 4 Gallons should do it with ease. Therefore based on the fact Miracle 511 costs around £70 a gallon trade the total cost should be £280 maximum. Added to this I still think it will go further on a roof.
Would you like me to send you a litre so you can do a coverage test on the exact type of roof???
