    Self-Cleaning Masonry
    paint by Johnstone's yet?

    I haven't used this product but I notice that the manufacturer claims a fifteen year life expectancy before re-coating is required.

    I have applied many different exterior wall paints over the years but the only one which I observe on a regular basis is the one on my own house. I last painted the pebbledash fifteen years ago with Dulux Weathershield Smooth in Sandstone and it still looks good with no obvious defects.

    Follow good working practise, use a good quality product, keep to the manufacturers instructions and you will most probably get a fifteen year job from most exterior wall paints.

    The 'microscopic nano particles' b****s in the Johnstone's product blurb I think merely refers to the method of measurement used which relates to the size and shape of the particles in a composite system. In other words Johnson's are claiming; very fine equals very high performance in both adhesion, cohesion and surface tension.

    Going a long way back, I remember so called self-cleaning paints being used in industrial work. In reality these paints were formulated to chalking prematurely and so would look good throughout the main period of their life expectancy.

    Pigments such as white lead and titanium have a tendency to chalking as does lithopone (not generally a good idea to use in exterior paint). Cheap paints often start chalking very early because they often contain excessive amounts of the extender Barytes.

    However, Johnstone's claim their product is not prone to chalking but instead relies upon it's extremely smooth surface finish. I would take a guess that they have used a modified silicone resin in this paint.

    Anyway,I shall give it a try at the next appropriate opportunity to see how it performs.

    are you having a laugh, you can paint with the best paint in the world and some are very much better than others but no paint is going to clean itself, it's like saying i have a self cleaning oven, oh yeah iv'e just done some roast spuds at 290c and the oven will clean all the fat off for me, dont think so, nice self cleaning paint and some filthy scro*t pi**es up it oh it's ok the paint will clean it up.

    Consider the product within the bounds of reasonability not extremism. There are and have been other products within this catagory on the market such as Glidden Endurance 'Pliolite' Based Masonry Paint, and of course Leyland produced a similar product which also used 'Pliolite' which I believe is a Silicate/Acrylic resin. This new product by Johnson's may just be a modification of the Leyland branded paint or indeed the very same product.
