Product Details

Specialist low odour sealer for internal exposed brick walls

Interior Brick Sealer & Dustproofer is low odour, easy to use and dries rapidly. Perfect for sealing old and new porous brick work on internal walls. Historically making internal brickwork and natural stone ‘dustproof’ meant using a non-breathable coating. This is not the correct way to seal old brickwork or natural stone. Our internal brick sealer will seal the brick and allow the surface to breathe. It is safe to apply to older rubble filled walls and any surface which requires water vapour transmission. The older style non-breathable sealers meant that the surface could not transmit water vapour leading to various problems. A few of the issues associated with non-breathable coatings are –

  • Moisture becoming trapped between the surface of the stone/brickwork and the sealer. This can make the surface look opaque/white and grey. It could also lead to surface spalling and damp leaching into associated structures.
  • As a non-breathable coating starts to break down, efflorescence and spalling accelerates the delamination of the sealer & treated surface.
  • The surface becomes darker and unattractive. Over time excess trapped moisture darkens the surface.

The bricks and stonework in older buildings are often soft and friable leading to natural dusting. In addition to this buildings have become warmer as they are now heated by more efficient heating systems. This can also accelerate the dusting from brickwork and stonework, surfaces have slowly become drier and shed more material into the atmosphere of the room.

Sealing brick also builds a dustproofing barrier for low maintenance

Dustproofing will help reduce any material becoming detached from walls and becoming airborne dust. This prevents the dust contaminating computers and contributing to poor air quality for the occupants. Keeping dust to a minimum is very easy, simply apply Interior Brick Sealer & Dustproofer. It is cheap and easy to apply via low pressure sprayer brush or roller. Interior Brick Sealer & Dustproofer will also seal other friable surfaces associated with dust problems. These might be old lime mortar joints or cement/concrete based materials. Interior Brick Sealer & Dustproofer is an excellent sealer and dustproofer for Yorkshire sandstone walls. Older sandstone walls will often be rubble filled and will require full moisture vapour transmission. They are often very dusty and will continue to shed dust once a building is occupied. Our internal brick wall sealer will help protect against dusting and water based staining. This product is an easy and cost effective way of sealing your internal structures. It is low odour, water based and a non-flammable product, therefore safe to use around fireplaces. Seal any exposed brick wall or natural stone wall quickly and effectively with this product. One coat is usually sufficient to dustproof but could be used in multiple coats. Interior Brick Sealer & Dustproofer can very delicately increase the natural earthy colours associated with old brick and stone. However, this product will not make your interior wall look shiny or unnatural, the sealer compliments the surface it is applied to. Interior Brick Sealer & Dustproofer does not drastically change the appearance of old stone or brickwork. It will still retain its original character but will now resist staining and dusting. To apply this product use a low pressure pump up sprayer, brush, microfibre cloth or a roller. Remove all obvious loose material and dust from your brick or masonry feature. Apply the sealer and allow the solution to soak in and bind the surface. It will dry in approximately 1 hour and cures in approximately 24 hours. Interior Brick Sealer & Dustproofer is perfect for older buildings and newer structures.

Interior Brick Cleaner is the perfect accompaniment to Floorseal Interior Brick Sealer & Dustproofer. It is a water based, low odour and a non-acidic intensive cleaning solution. This brick & masonry cleaning product will remove dirt, grime, waxes and light grout/cement haze residues. It is safe to use on lime pointed walls.

How many coats should I apply?

One coat is sufficient to dustproof the surface. You may wish to apply further coats to if you wish to obtain a subtle satin finish.

Is this product water-based?

Yes this product is water-based. Therefore it is low odour, free of solvents & VOCs.

What is the best method to apply the product?

Use a normal paint brush, or possibly a textured masonry style roller. For larger areas the sealer can be sprayed on with a low pressure pump-up sprayer.

Does this product dry on the surface?

It is designed to partially soak in but some product remains on the surface to bind dust.

I'd like some sort of a sheen, is that possible?

Interior Brick Sealer & Dustproofer can create a sheen when built up in multiple thin coats. The level of sheen will be dependant on the porosity of the surface. In one single coat it will be a natural matt finish.

Does this product stop damp coming through the wall?

This product stain proofs the wall and prevents dusting. It will allow water vapour transmission for breathability.

To prevent moisture travelling through the wall from the outside apply Floorseal Render & Masonry Sealer.

Render & Masonry Sealer is a waterproofing agent which resists rainwater, organic growth & carbon deposits. It is to be applied to the exterior walls of any structure which constructed or porous materials. Such as natural stone, sandstone, slate, limestone & granite.

Will this product alter the colour of my brickwork?

This sealer is not designed to colour enhance or alter the colour of stone or brickwork. We recommend testing the product on any surface before applying to the entire surface though.

What should I clean my brick work with?

Use Floorseal Interior Brick Cleaner. It is a modern eco-friendly, water based & non-acidic cleaner. This product will remove dirt & ingrained grime. It is suitable for use on brick & masonry walls and floors.

If you have a contamination of cement, lime or grout staining use Floorseal Cement & Grout Haze Remover. It should only be used on acid resistant surfaces i.e. clay bricks or sandstones etc.

I have had my brick work sandblasted, will this product dustproof it?

Yes this product can dustproof soft sandblasted bricks and masonry.

Prepare the surface by vacuuming away all lose dust before sealing. Sandblasted surfaces are very porous therefore absorb more product.

Can I use this product on lime pointed walls?

Yes this product can be used on lime pointed brick or masonry walls.

You can also safely pre-clean the walls with Floorseal Interior Brick Cleaner.

My wall is very rough how do remove sealer which has collected in the joints between the brick?

After 10 or 20 minutes you can wipe over the surface with microfibre cloths. This will prevent you from overapplying the product. Most of the product will simply soak in, any excess can simply be wiped over the surface producing a thin even application.

Could I apply this product with a microfibre cloth, my walls are smooth and not very porous?

Yes you can use a microfibre cloth to apply the brick sealer. Apply the product with a roller or brush and then wipe/spread the product over the surface with the cloth so a very thin coat is produced. Or soak the cloth in the sealer and wipe directly onto and over the surface.

Does Interior Brick Sealer & Dustproofer have a strong odour?

No it does not, it is free of solvents & VOCs.

How long does this product take to dry?

The sealer dries very quickly – within one hour. Probably more quickly than this in a warm environment.
