Sealing Indian Stone Paving..... Fossil Mint

[aspley]

Hi Guys........last year I laid some Fossil Mint Indian Stone Paving......looked the dogs when it first was laid but it very quickly attracted algae and needed jet washing. After six months it needed another clean and now, six months later, it needs some more attention.
It is laid in a south/west facing area of the garden so gets its fair share of drying sunshine.
So, the question is:- is this kind of paving vulnerable to attracting algae and if so does anyone have experience of a paving seal remedy??

Fossil mint is one of the most soft and porous sandstones and as a result gets dirty very quickly.

Using chemicals is more effective than jet washing and much better for the paving and pointing.

A hard surface cleaner like 'wet and forget' or 'patio magic' will keep it looking good but they won;t deal with very heavy algae very well.

If its very bad then using hypochlorite bleach is the most effective. There are good instructions on the paving expert dot com website.

Sealing will help reduce the need for cleaning but only if you use a proper solvent based sealant like lithofin stain stop or drytreat which are effective for many years but pretty spendy. probably looking at 200 quid for an average patio also it needs to be bone dry
