Natural Uncut Limestone patios & walkways

[E P W 14]

I went to look at a jop today thats about 5000 sqft of limestone sidewalks and patios. The rock is not anytype of manufactured product its just texas limestone.

I did a test run on it but was not to happy with the results.

Does anyone know what chemical of soap that would give me better results?

I just recommend being careful on going too acidic with natural stones. Don't use a coatingh persay but rather a suitable penetrating sealer (non glossy) that is natural looking.. :)

Just use bleach to clean up the Mue and a sorface cleaner.

yea there ya go..Listen to James here and go all the way the other way on the ph spectrum. It'll kill anything organic that is discoloring and make it real even looking without damaging anything (except landscape if you don't take precautions)

.. what color is this perticular stone?

[E P W 14]

Lightning, MMI & James , thanks for the input

The stone is white and offwhite, I wish I could use my surface cleaner but the rock is to uneven,

I sure the bleach will take care of the mold and black stuff,

What would yall suggest on the brown water stains around the bottom of the house

Don't use bleach on limestone, it can discolor it.

Henry, how does it do that by getting rid of the mildew ? You can use bleach to clean up any biological stain on stone.

I use Limonene on the stone patios I have a 12000 sq ft one I do every year with about 150' of wall that is 5' high. I found that the light detergent application lifts the dirt and mildew without being too aggressive to the stone and have never had a problem with discoloration. The first time I washed it had been about 5 years since it was previously done and it really did not take much effort to get it clean.
