With all the litigation on products and workmanship these days manufacturers and applicators are very reluctant to advise or specify which can often be over or beyond what seems sensible because of fear of litigation.
The litigation has pushed up the price and specification of many things because when your in court and its cost you a motza the discretion of the court is merciless in what it deems practical. They dont have the money for that kind of thing. One has left the industry. Because there is so many grey areas with employment, safety and product on items that may be for incidence deemed to be as safe as practical you will see a lot less recommendation and higher prices to cover risk and litigation.

Excessive alkalinity can damage paint Alkalinity is another serious issue to consider before painting brick. Though bricks are usually neutral, the mortar in which they are set contains certain soluble mineral salts, commonly referred to as alkalis.
Free alkalis affect oil-based paint products, eventually leading to the disintegration of the entire paint film — a phenomenon technically referred to as saponification. Applying an alkali-resistant primer is recommended to prevent alkali-based paint failure.
On-going maintenance is necessary Once you paint brick wall surfaces, you need to repaint them on a regular basis. Though wall maintenance can be annoying, keeping painted surfaces in good condition will provide adequate protection against the elements and prevent the premature degradation of your wall system. One way to avoid frequent repainting is to go for a top-quality primer and paint and a light shade, such as off white, cream, eggshell, vanilla or ivory.
