Since its launch, FUGA-PAVE FLEX XP has become one of the most popular external paving grouts for porcelain and natural stone — and it’s easy to see why. Customers are drawn to its beautiful colour range, straightforward application, fine finish, and the fact that it’s formulated to significantly reduce efflorescence and staining. It’s a grout our customers consistently come back to tell us they’re delighted with: strong and flexible joints, clean colour-stable results, and a process that works equally well for professional tilers and confident DIYers.

FUGA-PAVE FLEX XP is suitable for joint widths from 3mm to 30mm and depths from 10mm, compatible with porcelain paving (including 20mm porcelain paving slabs), natural stone, sandstone, limestone, marble, slate, quartz, terracotta, ceramic and concrete — a professional-strength outdoor porcelain grout that’s equally at home on a residential patio or a large commercial project, for both internal and external applications.

We’re a small, family-run business — I’m Cleo, the owner, with over 25 years in the construction industry working with businesses including Tarmac and Instarmac. I work alongside a team of incredibly knowledgeable and caring individuals, and between us we’ve seen a lot of paving grouts come and go. FUGA-PAVE FLEX XP has earned its place in our range.

We confidently recommend FUGA-PAVE FLEX XP grout for the majority of porcelain and natural stone grouting projects where joint widths fall between 3mm and 30mm. It works particularly well on porcelain paving slabs — including 20mm porcelain paving — and on sawn or riven natural stone paving. For very narrow joints of 1–5mm, you may want to consider a specialist epoxy grout instead; give us a call and we’ll point you in the right direction.

FUGA-PAVE FLEX XP grout is part of the complete FUGA-PAVE Outdoor Tiling System, alongside FUGA-PAVE Hybrid Mortar (formerly Part A) and FUGA-PAVE Slurry Primer (formerly Part B) — a coordinated system designed to work together for secure, professional porcelain and natural stone installations. No extra additives needed — just mix with clean water.

FUGA-PAVE FLEX XP was launched in August 2025 as the upgraded successor to FUGA-PAVE FLEX CH Grout — its previous brand name. If you’ve used FLEX CH Part C on previous projects, FLEX XP is its direct replacement, now with improved cleaning properties, better workability in colder and damp conditions, and more sustainable, reusable packaging.
