Maxisil Silicone Sealants — Australia's Premium Silicone, Colour-Matched for Tile Pros

Maxisil is Australia's premium silicone sealant brand, and it's finally here in the States. Built for contractors and trades who care about their work, Maxisil delivers 100% pure silicone that tools to a smooth, professional finish in less time — and holds up for years in the wettest, hardest-working areas of the job. Tile ProSource is proud to carry the full Maxisil range.

What sets Maxisil apart is that it's engineered by application, not sold one-size-fits-all:

- Wet Area Silicone — 100% pure, mould-resistant silicone for showers, bathrooms, and wet areas that stays flexible and clean.

- Natural Stone Silicone — a non-staining formula made specifically for marble, granite, limestone, and other porous stone, so you never get the oil-bleed halo that ruins a premium stone job.

- Pool & Fountain Silicone — built to stand up to constant water immersion and pool chemicals.

- Waterproofing (Maxisil Membrane) — silicone made for waterproofing detail work and changes of plane.

Then there's the game-changer: the Maxisil Color Cross-Over. Maxisil's silicone colour range is matched to all the major grout brands — Mapei, Laticrete, Ardex, Custom Building Products, Bostik, North American Adhesives, TEC, and Maxisil's own grout — so the silicone in your corners and changes of plane matches your grout line exactly. No more "close enough" caulk lines on a high-end install.

Once you switch to Maxisil, it's hard to go back to cheap, stringy caulk. Shop the full Maxisil collection at Tile ProSource — seal it, match it, and finish it right, every colour, every job.
