    Going to use some. Had the Keim rep out and he was very helpful but its just eyewateringly expensive. I have used it in the past and I know its good.

    But why is it so much dearer than others? Mike Wye seems to supply his own for really good price (1/7th of Keim price) and Earthborn have a good price too.

    So why pay the dearer price? Are there varying qualities?

    Why and where are you mineral silicate paint?

    I'm going to try a supplier here that's much cheaper also. I'll post back when I have more information.

    Using it on some external walls where the lime wash doesn't last so well.

    Have used Keim on a number of occasions and you cannot beat it.

    I used it on a listed building 9 years ago. Apart from traffic dirt there is absolutley no sign of paint deterioration.
    Whilst the paint is expensive if you factor in the saving in labour from repainting after 5 years the long term saving is significant.

    I would not use anything else externally. The earthborn looks a similar product and don't think the price is that different.
    I always get trade prices on Keim I think they give you 25% but you have to ask.

    Keim pricing is colour dependent as well so worth checking which colour group you have chosen.

    Are all silicate paints the same? Beeks has been suggested to me for a Granite built (soon to be) lime pointed barn on a hill in West Penwith. At some points this winter it was like having a jet wash on the building - 90+ mph! Some parts will be left as natural stone & some parts painted white, so a clear coat is essential. I had never heard of Keim, but a quick look on wikipedia showed that they were the original manufacturers - are they the best?

    Keim is very very good stuff.

    But Mike Wye sells SecilTek paint for 1/4 of the price of Keim.

    So I'm struggling to justify Keim

    I think mineral silicate paints are based on a chemical reaction similar to "limewash" but more durable, so in theory other manufacturers should be able to replicate the reaction.
    From Wikipedia
    While lime-based binders carbonate under influence of carbon dioxide and water silicate-based binders (usually potassium silicate resp. potassium water glass) solidify under influence of CO2 and in contact with mineral reactive partners form calcium silicate hydrates

    Hi Selly and all. I'm also considering mineral paint options and was wondering what you eventually decided upon and how it worked out for you? Any information would be gratefully received especially since you were doing this 4 years ago so might have some really good information at this point.

    I have just started a new discussion here regarding my particular question:

    Many thanks,
