Impregnating Sealer for Slate in a DRY Natural Finish
Highly protective slate sealer for slate floors and patios. If used as a slate floor sealer it will not change the appearance of the slate, leaving it looking totally natural.
Smartseal Slate Sealer is a high quality, clear, solvent free acrylic impregnating coating system, suitable for both internal and external surfaces. Application of the sealer will alter the chemical structure of the slate or natural stone providing a excellent water repellent and stain resistant surface.
One coat application to saturation
Resistant to algae, lichen and staining
Will leave surface "dry/natural" looking dependent on porosity/colour of surface
Average coverage: 1st Coat 8-10 m² per litre, 2nd Coat (if required) - much greater coverage can be expected.
Application by cloth, roller or sprayer
Touch dry 2-3 hours
Fully waterproof 24 hours
PREPARATION: Prior to application of Slate sealer or natural stone sealer ensure surfaces to be sealed are clean, dry and free from contamination. If algae or stains are present pre treat prior to cleaning with a appropriate cleaning product. If required, fully clean off using a pressure washer and leave to dry thoroughly for at least 3 days.
Always test product on-site, in an inconspicuous area, to ensure you fully are satisfied with the final appearance/ colour of the surface.
**If applied to a surface where a "sweep-in" pointing compound has been used, the natural stone must be fully cleaned with Smartseal Residue Remover prior to the slate sealer being applied.**
APPLICATION: Shake container well before use. Apply by pressure sprayer, roller, sponge or brush. Application on vertical surfaces should be to full saturation commencing at the bottom and working upwards. Do not apply in damp conditions and only apply to dry surfaces in temperatures above 13°C and no higher than 23°C. It is very important to make sure no rain is forecast for at least 8 hours after application.
Applying one coat to saturation is normally sufficient. For best results, apply one coat to saturation and once touch dry, a 2nd lighter coat can be applied ('wet on wet' finish). If over application does occur on either coats, excess sealer can be removed with a dry roller or sponge. Ensure this is done within 45 minutes.
All equipment should be cleaned with water immediately after use.
SHELF LIFE: Store away from direct sunlight and sources of heat. Protect from frost.
12 months shelf life (in original sealed container). Once opened use within 3 months.
Frequently Asked Questions
I have seen your anti slip product online, is this suitable to add with the sealer for my natural stone patio.?
Anti Slip is not required for natural stone surfaces. Natural stone sealer penetrates into the stone so would not leave any resin on the surface.
