The LTP Mattstone Sealer is a natural matt impregnating sealer designed to protect porous stone and masonry surfaces while keeping their appearance as close to untreated as possible. Ideal for customers who want subtle protection without introducing an unwanted shine, it helps defend surfaces against water, oil and grease while allowing the material to breathe naturally.
Formulated for a wide range of natural and man-made surfaces, LTP Mattstone Sealer is suitable for limestone, marble, slate, sandstone, travertine, terracotta, quarry tiles, concrete, brick and external paving. This makes it a versatile option for both fireplace and household projects, as well as broader interior and exterior stone sealing applications where a low-sheen, natural-looking result is preferred.
One of the main benefits of this sealer is its minimal change to the natural appearance of the surface. Rather than creating a glossy or overly enriched finish, it preserves a completely natural matt look while still delicately enhancing the colour and texture already present in the material. This makes it especially attractive for more understated stone finishes where the aim is protection without altering the character of the surface.
As an impregnating sealer, LTP Mattstone works below the surface to help reduce absorption and make ongoing maintenance easier. By helping protect against staining from everyday spills, dirt and grease, it supports better long-term care of porous materials in areas that see regular use. Suitable for both interior and exterior use, it offers flexibility for fireplaces, hearths, floors, paving and other stone or masonry features around the home.
Available in 500ml, 1 litre and 5 litre sizes, it can suit smaller domestic applications as well as larger sealing projects where more coverage is required.

Expert Insight
A matt impregnating sealer is often the right choice where the goal is protection without making stone look coated or shiny. On more characterful materials such as limestone, slate or honed stone, keeping the finish natural can be just as important as protecting it from staining.
Suitability
The LTP Mattstone Sealer is well suited to stone fireplaces, hearths, worktops, floors, paving, and other porous natural or artificial stone surfaces where a breathable protective treatment with a natural matt finish is preferred.
