Everbuild 409 Block Guard 5 Litre – Key FAQs
What does Block Guard do?
It seals the paving surface and helps stabilise kiln-dried jointing sand, reducing sand loss and improving resistance to water and common stains.
What surfaces can it be used on?
It’s designed for block paving and other mineral paving surfaces. For natural stone, always test a small hidden area first to confirm the finish.
Does it change the look of the paving?
Yes, it enhances colour and typically leaves a subtle sheen that lifts the appearance of the surface.
How many coats do I need?
Two coats are recommended for best performance. Very porous surfaces may absorb more product and affect coverage.
How long should I wait between coats?
Allow at least 3–4 hours minimum between coats, depending on conditions and how quickly the first coat has dried.
How do I prep the joints before sealing?
Joints should be filled with compacted kiln-dried sand and the surface must be clean and completely dry before application.
What coverage will a 5L tin give?
Coverage is typically around 5–7m² per litre per coat, so a 5L tin covers approximately 25–35m² per coat depending on porosity and surface texture.
(Please note that tins may get dented in transit and this is not a reason for return please do not purchase tined products if this is an issue for yourself.)
