Porcelain pavers are low maintenance but still need regular cleaning and care to last, says Mark Atkins
2025 saw a shift in external porcelain, with engineered slabs dominating market growth. Once niche, these pavers are deservedly top choice for external patio installations, especially in contemporary settings – they’re durable and resistant to stains, frost and fading.
Being dense and low-porosity, they absorb little moisture, so they stand up brilliantly to foot traffic and extreme weather. But, while low maintenance, they’re not ‘self-cleaning’.
Dirt, organic matter, algae and everyday grime will accumulate on the tile surface, particularly in damp, shady spots. To maintain performance features, regular maintenance is important. Spring is the best time to start.
Cleaning porcelain pavers
Clean porcelain paving every couple of months over the spring/summer and twice during the autumn/winter. Regularly cleaned surfaces will be easier to keep clean. Regular cleaning of inside-to-outside tiles, like those running through bifold doors, will help maintain a seamless aesthetic.
Jet-washing may seem best for a fast clean but it’ll only wash dirt off the pavers’ surface, leaving residue lodged in the tile’s textured surface, so attracting more dirt and residue.
You can reach this by using alkaline-cleaner and allowing sufficient contact time to breakdown accumulated matter. If the build-up comprises slippery green slime and organic residue, a specialist blackspot and algae remover provides the most thorough clean and helps prevent regrowth; the contact time for this type of treatment will be longer, to target the algae’s hyphae or filaments which will be anchored into place.
Avoid acidic solutions. While porcelain is acid-resistant, cementitious grout joints aren’t. Other stains, like cement, grout, efflorescence etc, are best tackled with a professional stain remover formulated to remove these residues.
Recommendations for new installations
External porcelain pavers don’t need to be sealed but their textured finish can create a challenge during installation. Grout and brush-in jointing compounds tend to get stuck in the tile’s high/low surfaces, along with dirt and residue, creating white film on the tile’s surface. This loss of texture can compromise slip-resistance. Applying a quality porcelain tile protector before grouting will help protect the tile’s surface from cement and resin staining during installation. It’ll also help improve and increase the working time of the grout or jointing compound, by preventing rapid moisture absorption and keeping it fluid for longer.
As a bonus, the treatment will leave invisible active ingredients behind which provide protection, making residue removal easier. Once residues are removed and the surface is dry, a further coat across the face of the tile and the joint will make ongoing cleaning and aftercare easier.
Further resistance to foot traffic, wear and stains can also be added-in with the application of a porcelain tile enhancer. These create a sheen without compromising slip-resistance. Look out for a breathable water-based treatment, to avoid moisture becoming trapped under the finish, and for a PFAS-free solution to ensure a safe application.
