Product Details

100% breathable sealer guarantees full water vapour transmission

Natural Stone Sealer Breathe is a water based impregnating & breathable stone sealer. It can be used on internal and external natural stone surfaces. This breathable stone sealer will dry to matt finish, so does not alter the appearance of natural stone. It can be used on Indian sandstone, Yorkshire sandstone flags, limestone, travertine, slate, porous granite, clay-based tiles & flints etc. Natural Stone Sealer Breathe is a modern high performance fluorocarbon impregnating sealer, providing protection against water and oil-based staining. The application of Floorseal Natural Stone Sealer Breathe will make general maintenance easier. This product inhibits efflorescence, moss, algae, black spot lichens and other organic growth on external surfaces. When applied to internal walls and floors it provides protection from water & oil-based staining. It will make general maintenance easier as the sealer turns back liquid staining. This breathable stone sealer is suitable for sealing patios, general masonry, old rubble filled walls & brickwork. It is safe to apply to external walls or within listed buildings as the sealer allows full moisture vapour transmission. This includes sealing gable end walls which have been lime pointed and are rubble filled.

Easy to apply stone sealer, with a safe water-based formulation

Natural Stone Sealer Breathe is easy to apply with a low pressure sprayer, roller brush or paint pad. Simply build to saturation & remove the excess with microfibre cloths. Apply again approximately 40 minutes to an hour later for full protection. Natural Stone Sealer Breathe allows full water vapour transmission, therefore moisture clouding issues associated with topical non-breathable sealers do not occur. Unlike topical surface coatings this product will never require stripping due to wear, blistering or flaking. In the future the sealer can simply be applied again, this may be around 4 – 5 years after the initial application. Natural Stone Sealer Breathe is meshed into the pores of the stone so cannot actually wear away from the surface. It is not designed to create a surface sheen or shine, its purpose is to leave the treated surface with a totally natural appearance. Natural Stone Sealer breathe can be used on any porous natural stone or other porous surface like clay-based tiles or concrete. This natural stone sealer is suitable for use on internal or external surfaces. This product can also be used as a pre-sealer when applied in a single coat.

Available in 1 litre, 5 litre & 20 litre containers with free standard delivery & express shipping options. Samples are available.

Coverage

Approximately 8m2 per litre for the first application & 16m2 for a 2nd application. Typically, a 5 litre container will cover 20m2-25m2 of surface area accounting for both applications.

The individual level of porosity of each type of surface will dictate the overall coverage.

Frequently Asked Questions

Is Natural Stone Sealer Breathe a fully breathable stone sealer?

Yes, it is fully breathable so allows full water vapour transmission. Therefore no trapped moisture or moisture clouding issues.
Is this product visible on the surface?

No, it is designed to soak into the surface and any excess is to be wiped away. The product leaves the protected surface with a totally natural appearance. The sealer is meshed into the pores of the stone. It is not a surface coating or lacquer so will not blister, flake or peel.
Can I use this on the exterior walls of my house?

It is possible to use this product but we would recommend either Floorseal Render & Masonry Sealer or Floorseal Breathable Brick Sealer & Waterproofer to seal exterior walls. Both products are breathable impregnating sealers but more suited to exterior surfaces.
Will this product dustproof my interior stone and brickwork walls?

No, it will not dustproof walls as it is an impregnator. Impregnators do not dustproof they resist oil and water-based staining. Please use Floorseal Interior Brick Sealer & Dustproofer to seal and dustproof internal brickwork and masonry.

This product is the perfect product for sealing natural stone floors which should not require dustproofing. Floors typically do not need dustproofing – The need to prevent dust from shedding usually relates to exposed older vertical bricks. You could have a look at our ‘how to guide’ section at the top of the page about sealing against dust.
Is this an interior or exterior product?

It can be used on internal or external horizontal surfaces to seal against water & oil-based staining. It will also inhibit organic growth on exterior floors.
Why do coverage rates seem to vary?

Because some natural stone is more porous than another form of natural stone.

As an example sandstone is very porous and can become significantly more porous when sandblasted.

Slate tends to be less porous than any type of sandstone etc.

As an idea 5 litres of Floorseal Natural Stone Sealer Breathe will cover approximately 20m2-25m2 of sandstone flooring. This includes applying in 2 consecutive applications.
Can I apply Natural Stone Sealer Breathe to a stone floor in a listed building?

Yes, it is fully breathable so allows moisture vapour transmission even when there is no damp proof membrane present. Natural Stone Sealer Breathe can also be applied to lime pointed walls or floors.
Will Natural Stone Sealer Breathe change the appearance of my natural stone?

No, not at all  – its purpose is to create a water and oil-resistant surface whilst retaining the natural appearance of the stone.
Does this sealer contain solvents? Does it have a strong odour?

This product is solvent free & contains no VOCs. It is water-based so very low odour.
Can this sealer be used to seal a natural stone patio?

Yes, it is an ideal product for sealing natural stone patios such as sandstones, slate, limestone and other porous surfaces. We recommend sealing Kandla Grey or mid grey sandstones with this product.

Please read our useful ‘how to’ guide for sealing Kandla Grey sandstone or mid grey sawn sandstones.
