Characteristics:
Premier Stone Guard Sealer can be used on many different types of natural stone and other porous paving materials. It reduces the absorbency of the treated paving and largely prevents water, oil and grease penetration. Any spillages or contamination remains on the surface and the area is therefore easier to clean. The colour of the paved surface is not significantly changed, if at all, although a few very sensitive substrates may look darker.
Always apply a test area first!
Premier Stone Guard Sealer must not be used on areas already pointed until any residual binder has completely weathered away.

Requirements:
A clean and dust-free, structurally sound, absorbent and dry paved surface which is otherwise ready for pointing; or
with pointing that is fully cured and has no residual binder on the surface. Ambient and surface temperatures minimum 10 °C / 50 °F, maximum 25 °C / 77 °F, with dry weather conditions and no rain or heavy dew forecast for at least 24 hours.

Tools:
Brushes, rollers or low pressure sprayers, plus sponges to remove any excess.

Application:
The areas to be treated should be completely dry, clean and free from any dirt or contaminants that could prevent or reduce penetration. Apply Premier Stone Guard Sealer with a suitable brush, roller or low pressure sprayer evenly over the surface to saturation, but avoiding any residual ponding or puddling. Remove any excess with a sponge; this is particularly important on surfaces with uneven absorbency, otherwise localised darkening can occur. Avoid splashes on adjacent materials and remove any spillages immediately with a damp cloth. Suitable PPE should be used, including goggles and gloves etc.

Curing:
Protect area‘s treated with Premier Stone Guard Sealer from moisture and any other dirt or surface contamination for a minimum of 5 hours before access, 24 hours before use (at 20 °C / 68 °F and 65 % relative humidity). When completely dry, the treated paving can also be pointed with the appropriate vdw jointing mortar, if this was not completed before the treatment.
