MatteSeal
Water-based sealer for stone and stucco
A silane-siloxane sealer that soaks into the pores rather than sitting on top — water beads off, but the stone still breathes and still looks like stone.
Use it for
- Brick, concrete, natural stone, and pavers
- Stucco finishes and plaster mortar
- Flagstones and other porous masonry
- Interior and exterior surfaces exposed to weather
Why this one
- Keeps the natural look
Preserves the original colour and texture — no film, no sheen - Water beads off
Lowers surface tension so rain runs rather than soaks - Still breathes
Lines the pores without blocking them, so vapour still escapes - Abrasion does not affect it
Penetrates deep thanks to small molecular size, so wear does not remove the protection - Holds off moss and algae
And reduces efflorescence and surface salts - Easier cleaning
Prevents build-up of dust, dirt, oil, and other chemicals
