Fluropolymer on indian sandstone.
« on: December 21, 2012, 06:44:45 pm »
Fluropolymer on Indian sandstone. Anybody tried it? In theory it should work.It's breathable so moisture can escape from what is a very porous surface. Moisture peculates upwards from the substrate below...but it is hydrophobic so burger fat, red wine ,water cannot enter from above.
It is water soluble so no problem applying to a damp surface (Indian sandstone always has a high moisture content).
It is an impregnator so wear will not be a problem.It is also translucent so will not change the appearance of the stone will not change.    Anybody tried it? or know of the product?

I would contact Smartseal Chris, as I am sure they are going to be putting out a sealer that can go on damp at some point next year, Good Luck with that.

Sealers are no good Roger sandstone needs to breath. We should talk privately ...it would be to our mutual advantage.

And that is why I said "Good Luck" with that, in my opinion Exterior Sandstone doesn't really need to be sealed, just a good maintenance program in place.
We will seal if the client really insists on it, but I'll only use impregnators.

No I don't, I would have a look in flooring section, as there are people on that side that will openly give advice on sealers, Kevin Martin for one.

Why should I recommend a product and give out info? so that every tom, dick and harry can have the same knowledge without doing the slightest bit of research and testing for themselves.

Resiblock indian stone sealer is one of those i think, cant remmeber exactly but that rings a bell, it's defintely not a PU though, it works great, it should do at £90 a gallon!
there are various others out there such as lithofin aswell

 Roger ...I thought that was the whole point of this forum so people could swap ideas, recommend products,give an opinion on a subject?
Kenny... I have worked with Resiblock (the company and Resiblock the product) quite  a lot recently. I have been stripping driveways that have failed, nothing to do with there products (which are what i consider the best on the market)just application errors .Acrylics being applied over PU,s. Damp substrates with pu's applied.
 RESIBLOCK  '22'/A.F works well on Indian sandstone  the plus points is that it requires a certain amount of moisture to cure...this is one of the problems with sealing most substrates are never really completely dry.
The types of impregnators i wish to develop which i think suitable as they are waterbased  These would be basically teflon ...the coatings on frying pans .Hence the original post i wanted to see if anybody had experimented  with  Fluropolymer (teflon)

Most impregnator are fluoropolymer.
With the exception of silane based products such as Dry Treat Stain Proof.

There are plenty of water based impregnating sealers on the market. i used to use drytreat stuff in australia for sandstone/brickwork and it was good stuff. there are other waterbased sealers out there too. most companoes make them.

There are some new sealers/anti graffiti coating out there now based on liquid glass. there are other companies apart from smartseal/resiblok.

Your asking about a sealer to use on sandstone but in your last post you said that resiblock 22 works good on exaclty that.

I appreciate there are other company's out there.  I am also aware that some company's  exaggerate  just how good there products are. Hence asking the question to contractors that actually use these products. I need to know about how viable  in terms of wear and tear,sensible application rates, application limitations etc.
With all due respect what works in Australia might not be suitable in our enviroment

I understand that but as i now live in scotland and have tried a few different sealers ive come to the conclusion that all sealers need re application. impregnating sealers are longer lasting and not nearly as badly affected by the weather.

Matt which ones are you using and how do you find them? You might find this  http://www.scottsprofessional.co.uk/uk/proshield.html  useful if you are doing block paving although strictly speaking it should not be due to possible run off . Used sensibly though it's very good.

I can't be bothered with sealing - I use sealing to upsell the washing, "its cheaper to clean every other year than clean and reseal every five". I also tell them moss will grow on glass so how can a sealer work. I will only seal to enhance the colour if the customer really wants it and I happen to be in a good mood. I've not answered the original post have I ! Oh well its not quality street  ;D
I use PICS acrylic and resiblock PU - I find them by remembering that they are in the back of the container  :o

Chris I guess me & you will not see eye to eye how forums work, but that aside, if you are using Resiblock 22 on Sandstone and you say it has worked for you, then please let me know the results after say 1 year. Resiblock 22 is no more then a sand sealer for block paving (a glorified glue) and as a Resiblock contractor I think I know what I am talking about. 22 Does not need moisture to cure, surface and joins between pavers need to be bone dry, hence the sealing window in the UK can be a very short season, take this year for example. Resiblock natural stone sealers are OK-ish but there are better products out there, Lithofin is one, not cheap but you get what you pay for, Aqua-mix is also good on certain surfaces, again this is just my opinion after using/testing the above products.

People seem to think sealing exterior paving is easy money, do it right and it can be, do it wrong then it gets expensive putting it right.

Roger resiblock 22 af needs "atmospheric moisture" to cure . It works well on sand stone 1/2 (depending on traffic) years down the line it is still helping to preventing staining red wine ,beer,burger fat,lichen etc .
The sealing window this year and  in many years is very short this i will agree with, hence why i am interested in Fluropolymer waterbased products. In my experiance the waterbased products take twice as long to dry as solvented ones (generally) but they are less sensitive to moisture in the substrate.
Sealing paving is "easy money",given the correct expectations,products and weather conditions.
Resolving problems that have gone wrong with sealing projects by other contractors and homeowners is also "easy money " for me.
You mention Lithofin and aqua-mix being expensive but they work. I would rather pay extra for tried and tested products. In the end i have a reputation to uphold i would rather be remembered as being very expensive but worth it than cheap but "it looked ok in the beginning".
I give the customers a price for doing the job correctly... sometimes myself i think that the job is way too expensive but that is just how much costs these days!! A bar of chocolate is nearly a pound and they are getting smaller ;D
Roger thank you for your recommendations i will look at these products.

Atmospheric moisture Yes totally agree with, the point I was trying to get across is surface & joins needs to be dry. Some people reading these threads (IE new to this) could take it that "moisture cure" means a bit damp on the surface is ok because I read it on a forum.
As I have said before research & test for ones self to get a true feel of how these things work.
This place can be like Wikepedia, not always correct.

What are these newish damp seal products made of? the seal o block from jetstram and the adseal extreme, ive never used them, my mate had me strip a  PIC driveway last year that had meen done in adseal extreme, looked good for 6 month then started to look like it had bloomed, started to lift and take all the colour release with it, he asked me to strip and he has recoated with acrylic, he said he would nver use it again, he only tried it the once and look what happened.
he didnt do anythin wrong, followed the instructions etc and he has been laying PIC since 1998 and still going strong so i do not doubt his capabilities or story

I think that the Adseal extreme/Smartseal (not the same product)is just a waterbased acrylic  I have not used much of these products to give an opinion...the idea is good. My friend who is an industrial chemist...says they are Cr** (technical term!) Taking into account he has not used them or even seem them in use ,he is basing on his knowledge of the technology behind them. He is pretty good usually in his assumptions.
Creative impressions at preston  http://www.creative-impressions.com Have manufactured a waterbased imprinted concrete seal called gemseal ,i have used that. We are into the second year of it being down and it still looks good.
This is the problem with these products in that it can take 12/18 months before we know if they are any good!
