Dustproofing concrete


Porous concrete can cause problems to plant and machinery.  When airborne it can pose a risk to health for workers. It also means more time spent cleaning of the workplace.

Dustproofing is a cost effective way to seal your concrete floor, making it more robust. The major benefit is reducing the issue of dust. Water based concrete hardeners  don’t give protection from chemicals & acid. Clear resin sealers are needed for chemical resistance and also give a longer lifespan.

Cleaning and sealing old concrete
Heavy usage makes industrial floors become dirty and discoloured from forklift tyres. We are able to clean your floor using diamond grinders to remove the top layer of concrete, then  apply a concrete sealer / hardener that will help reduce dust levels. 

Dilapidations- removing walkways and sealing

We can diamond grind to remove any line markings and walkways, then seal the floor with a concrete sealer.

Types of concrete dustproofers:

Clear epoxy sealers will give a durable and long lasting finish. They resist chemical and soil spills and offer a dry film thickness of 200 microns per coat and have a gloss finish. Epoxy sealers are not UV stable.

Silicone based sealers will soak into the concrete and prevent water ingress once applied. We use Stormdry, it makes the concrete slightly darker for a few weeks then returns to its normal colour.

Polyurethane sealers are 2 part resin based, giving high traffic resistance and are UV stable. They cure to a gloss finish and are suitable for both internal and external floors. 

Water based epoxy sealers are best suited to new concrete with high moisture content. A 2 part system giving a dry film thickness of 100 microns per coat.


Clear epoxy sealers are most durable and also protect the floor from oil and chemical spills soaking into the concrete.
Water based acrylic dustproofers are more cost effective and heal reduce dusting of bare concrete floors.

Yes old concrete can be dustproofed, we usually prepare the surface with a light diamond grind to clean the floor then apply 2 coats of an epoxy or water based sealer.

If you pour a small amount of water on the surface, it will either soak into the concrete within a minute, meaning it it porous and could benefit from sealing. Alternatively it may bead up and sit on the surface, this is a sign the concrete is already sealed.

It is recommended to wait 30 days if using an epoxy sealer as the excess moisture in the slab needs to dissipate.

If using a water based everbuild type dustproofer we use a backpack sprayer to apply then back roll to ensure no puddles are left on the surface.
If using an epoxy we apply with a solvent resistant roller and cut in edges with a brush.

Case study: Dustproofing

We carried out a diamond grind to this industrial floor in London & applied 2 coats of Everbuild dustproofer. The pic shows the application of 2nd coat by sprayer and back roll. This industrial unit was a film set for an upcoming movie, ‘Cash Truck.’ The movie set had areas of the floor painted. These coatings needed to be removed when handing back the industrial unit to the landlord.
