This 5L Spear & Jackson Paving Sealant is designed for homeowners seeking to protect and enhance their outdoor paving surfaces. Its key benefit is creating an invisible barrier that repels common outdoor nuisances like algae, mould, grime, oil, and weed growth, significantly reducing maintenance time and costs. A potential consideration is that it is a ready-to-use formula, meaning dilution is not an option, and coverage is fixed at 25m². The product offers a straightforward solution for both porous and non-porous paving, strengthening surfaces and ensuring a cleaner, longer-lasting appearance.

The duration of protection can vary depending on environmental conditions and traffic levels, but typically offers effective protection against algae, mould, grime, and weeds for at least one to two seasons. Reapplication may be necessary for continued optimal performance.
It is generally recommended to apply to a clean, bare surface. If there is an existing sealant, it might affect the adhesion and performance. It's best to remove any old sealant or test compatibility on a small area first.
No, the Spear & Jackson Paving Sealant is designed to form an invisible barrier. It should not alter the colour or sheen of your paving surface.
The best time is during dry, temperate weather. Avoid application during frost, heavy rain, or extreme heat. Spring or early autumn are often ideal periods.
Store the sealant in its original, tightly sealed container in a cool, dry place, away from direct sunlight and frost. Ensure it is out of reach of children and pets.
While the sealant is designed to be durable, it's advisable to check manufacturer recommendations for specific paints or topcoats. Some products may adhere well, while others might require a different preparation method. Test in an inconspicuous area if planning to apply another finish.
Check that the hose trigger is securely attached to the bottle and that the nozzle is not blocked. Ensure the bottle is tilted correctly to draw up the liquid.
The paving may not have been thoroughly cleaned before application, or the sealant has not had sufficient time to cure. Ensure the surface was clean and dry prior to application and allow 24-48 hours for full curing before exposure to heavy rain or foot traffic.
This can occur if the application was inconsistent. Try to apply a second, thin coat after ensuring the first coat is fully dry. For future applications, focus on an even, steady spray pattern.
The sealant may not have fully cured yet. Ensure at least 24 hours of dry weather after application. If it has been longer and water is still penetrating, the coverage might have been too thin, or the surface may require re-application.
