Patio Cleaner Technical Data Sheet

Suitable for outdoor stone and concrete. Especially effective against patio black spots and other microbiological soiling.

General product description

A powerful and effective patio cleaner that will remove all types of general patio dirt and grime from stone surfaces. It can be used on all types of stone paving such as patios, paths and driveways using natural or manufactured stone and concrete. Suitable for all types of light and dark coloured outdoor stone including sandstone, limestone, marble, travertine and granite. The treated surfaces, including mortars and grout, will not have their colours affected, therefore it can be used to clean dark stains on joints.

Advantages and characteristics

The cleaner is a waterborne, easy to use product that is quick to take effect and gives long lasting results due to its deep penetrating action. It is an acid-free product, so it will not damage the surface being cleaned, unlike other acidic based products. Does not contain potassium hydroxide, hydrochloric acid or phosphoric acid. It will also brighten most surfaces.

Recommendations for use

Always carry out a test on a small area to determine the amount of time required for the cleaner to take effect.

The effectiveness of the cleaner will vary depending on:

Dry and warm conditions are ideal for the product to perform at its best.

Do not use when the surface is below 5⁰c or when the surface is saturated with rain.

The temperate of the surface being treated is important because this does need to be above 5⁰c for the cleaner to take effect. Before use, consideration should be given to the weather conditions, as low temperatures or an overnight frost will cause the stone to cool and if the cleaner is applied before the surface has warmed up, it will not activate.
