The stone and concrete sealer you won’t stuff up.
“Classic is my original recipe. I developed it over 20 years sealing billion dollar commercial projects and luxury homes. Same formula, every time. Two coats. Most jobs done in under an hour.”
— Matt Nash, Founder, Just Seal It
Classic is a professional grade penetrating sealer. Works from inside the surface, not on top. No film. No peeling. No colour change. No change to slip rating or grip.
Works on tiles, pavers, facades, stone and concrete. Indoors and out.
Clean the surface. Let it dry. Apply two coats with a microfibre applicator or low pressure sprayer. Full instructions in our how to apply guide.
Stone should look like stone. Topical film sealers make beautiful materials look plastic. They trap moisture, peel over time, and need stripping before you can reseal. Classic isn’t just any penetrating sealer. It was developed over years by someone who has spent two decades hands on with some of the most stunning architectural materials in the world, and is passionate about keeping them exactly as they should look. Protection from within. Full breathability. No compromise on character.
Your surface is near a pool, on the coast, or exposed to heavy salt and moisture. Classic is built for standard conditions. PLUS is engineered for harsh ones. Not sure? Email us with a photo and we’ll tell you in five minutes.
Tiles, pavers, facades, natural stone, concrete, bluestone, sandstone, travertine, limestone, marble, granite, slate, porcelain, terracotta, quartzite, porphyry, brick, grout, render, masonry and more. Indoors and out.
1L covers approx. 10m² (107 sq ft)
4L covers approx. 40m² (430 sq ft)
20L covers approx. 200m² (2,150 sq ft)
Coverage is a guide. Porous surfaces absorb more. If you’re close to a size boundary, go up. Running out mid-job means delays and having to come back to it.

There are many different materials out there, so it is impossible to list them all, so if the surface you wish to treat isn’t listed below, please get in touch so we can advise if we can help you!
Sealed surfaces are more durable, easier to maintain and possess an increased ability to withstand moisture related problems. #JUSTSEALIT penetrates deep into a porous material, physically altering the surface tension. A permanent chemical bond is formed after 30 days resulting in a hardier and more durable surface.
Corrosion can occur on untreated natural stone, tile, concrete and grout by being exposed to various environmental elements. Damage can be caused by mould/mildew, efflorescence, salts in pool water or even just slightly acidic PH rain water.
Application of #JUSTSEALIT will reduce or eliminate the impacts of corrosion. Efflorescence presents as an unsightly white powdery salt haze, and can cause permanent damage to a porous material if not addressed. It is a common occurrence in both natural and man-made stone, but can be significantly reduced or even prevented by treating with #JUSTSEALIT sealants.
But it’s not just about durability, it’s about preserving the beauty of materials shaped by nature.
Natural stone has taken millions of years to form, and each piece tells a story. Concrete and other engineered materials, while man-made, are crafted with intention, from brutalist design to refined architectural detail. These surfaces deserve to be defended, not disguised.
That’s why #JUSTSEALIT leaves no plastic coating, no artificial sheen. It forms an invisible barrier that strengthens and protects without changing the look or texture. Whether it’s hand-trowelled concrete, honed limestone, or custom brickwork, your surface stays authentic, raw, and real, just how it was meant to be.
Invisible. Durable. Breathable. True to form.
To ensure you apply your sealant in the most beneficial way, please follow these instructions and/or watch the application video.

Application
After sealing After sealing, ensure you follow best practice in the maintenance of your surface. Download our maintenance guide here.
How long protection lasts depends on the material, surface texture, environment and traffic levels. There’s no honest single answer. What we can say is that the chemistry itself is extremely durable. Unlike coatings, our penetrating sealers bond within the mineral structure rather than sitting on the surface, which is why they won’t peel, flake or delaminate. A maintenance coat every 3–5 years keeps performance at peak levels regardless of conditions.
No. Just Seal It products are impregnating sealers that absorb into the surface rather than sitting on top. When applied correctly, they do not alter the natural slip resistance of the material.
