Overview
Pavement Sealer is Stainstop Anti-Gum Pavement Protector + Fungicide: an invisible treatment for concrete, brick and natural stone paving and other masonry floors. One coat soaks deep into the surface and seals it while letting it breathe.
Once treated, chewing gum, water, oil and grease can no longer bond firmly to the paving. In most cases the action of street sweepers is all it takes to remove gum, spills and stains. A fungicide in the formula also kills moss, lichen, liverwort and algae, which helps keep slippery growth off paths.
Why choose it
- Stops gum sticking: gum bonds weakly to treated paving, so it can be cleaned off mechanically with little effort.
- Invisible: it soaks in rather than forming a visible coating, so the paving keeps its look.
- Repels oil, grease and water: spills bead on the surface until they’re mopped up, instead of soaking in and staining.
- Kills green growth: the added fungicide deals with moss, lichen, liverwort and algae.
- Long-lasting: typically effective for 3 to 5 years, depending on footfall. There’s no need to re-apply after gum has been cleaned off.
- Not hazardous: not classed as a hazardous substance under current legislation.
Where to use it
- Town centre high streets, precincts and shopping centres
- Outside takeaways and fast-food restaurants, where grease and dropped food darken the paving
- Petrol station forecourts, where oil, diesel and petrol spills stain
- School, campus and hospital entrances
- Paths under and around trees, where moss and algae build up
It suits concrete, brick and natural stone paving and other masonry floors. For driveways that need protection from tyre marks, see Block Paving Sealer.
How to apply it
- Clean first. Remove existing gum, for example with Chewing Gum Remover, wash the surface to remove contaminants and let it dry.
- Apply. Use a brush, roller or low-pressure sprayer at about 5 m² per litre, and allow it to dry.
- Second coat if needed. Very absorbent surfaces may need a second coat, applied at least 2 hours after the first has dried.
- Leave to cure. Allow 24 hours to dry before the area is used.
Don’t apply it outdoors if rain is expected while it dries.
How much do I need?
Allow about 5 m² per litre per coat: roughly 25 m² from a 5 litre container and 125 m² from 25 litres. Porous or very absorbent paving may need a second coat, so allow extra for those areas.
Storage and safety
Store between 10°C and 25°C in dry conditions. If it has been exposed to very low temperatures, let it warm to room temperature and stir before use. It has a minimum shelf life of 2 years when stored normally. Read the safety data sheet before use.
