This guide is for homeowners and contractors looking to enhance and protect their natural limestone surfaces. The StoneCare4U Essential Colour Boost Limestone Sealer deepens the natural colours and appearance of grey limestone while providing effective stain protection. A key caveat is that it will alter the stone's colour, so testing in an inconspicuous area is crucial, and it is not suitable for certain shades of Kandla Grey sandstone.

Yes, the 'Colour Boost' aspect of the sealer is designed to enhance and deepen the natural colours and appearance of the limestone. We strongly advise testing on an inconspicuous area first to preview the effect.
The stone surface must be kept completely dry through the curing process, which can take up to 72 hours.
No, the recommended application temperature range is between 15 and 23 degrees Celsius. Applying outside this range may affect performance and curing.
The sealer provides stain protection. Minor spills should bead up on the surface and can be wiped away. For best results, clean spills promptly.
No, this product is specifically for natural limestone. It is explicitly not suitable for Kandla Grey (mid and light grey) sandstone.
No, the sealer should not be diluted. Apply it directly from the container.
Two coats are recommended for best results. Apply the first coat, remove excess, then apply the second coat approximately 45 to 60 minutes later.
This may be due to uneven application or not removing excess sealer promptly. Ensure even coats and remove excess within the 20-30 minute window. For existing issues, some light abrasion or reapplication might help, but test first.
Ensure the surface was completely dry before application and that the ambient temperature is within the 15-23 degrees Celsius range. Check that the surface is protected from rain during the 72-hour curing period.
This can happen if excess sealer was not removed or if the surface was not completely dry before application. It may require careful cleaning or reapplication after thorough drying.
Verify that the stone is indeed natural limestone suitable for this product and not a type explicitly listed as incompatible (e.g., certain Kandla Grey sandstones). Always test in a small, hidden area first.
Preparation is Key: Before application, ensure the limestone surface is completely free of loose debris. Critically, the surface must be dry. Allow at least 72 hours of clear and dry weather for the stone to dry thoroughly before sealing. The ideal application temperature is between 15 and 23 degrees Celsius.
Application: Do not dilute the sealer. Use a low-pressure sprayer, roller, natural fibre brush, or sponge to apply the first coat. Within 20 to 30 minutes, remove any excess sealer from the surface. Apply a second coat approximately 45 to 60 minutes after the first.
Curing: The sealed stone surface must remain completely dry for up to 72 hours during the curing process. Protect surfaces not intended for sealing with masking materials.
Compatibility: This product is specifically for natural limestone and is designed for grey variants. Important: It is *not* suitable for Kandla Grey (mid and light grey) sandstone. Always test in an inconspicuous area first to see how the sealer affects the colour and appearance of your specific stone.
Care: Once cured, the sealed surface can generally be cleaned with water and a mild detergent. Avoid harsh abrasive cleaners that could damage the protective layer.
