Concrete is strong, durable and widely used across homes, commercial buildings and outdoor spaces in the UK. You will find it in driveways, patios, garage floors, paths, garden walls, steps, workshops, warehouses, balconies, façades and utility areas. Although concrete looks solid, it is naturally porous. Water, oil, dirt, algae and other contaminants can enter the surface and cause staining, ageing, cracking, frost damage and surface deterioration.
Sealing concrete is therefore not just about appearance. It is an important part of long term protection. At Nanocoating.co.uk, we sell a complete concrete cleaning and protection system:
-
NC Nano Stone Cleaner for cleaning concrete, stone and tile surfaces before sealing
- NC Nano Coating for Stone, Concrete & Tile for making concrete water repellent, dirt repellent and easier to maintain
Together, these products help protect concrete from moisture, stains, dirt, algae, frost related damage and premature wear, while keeping the natural appearance of the surface.
Quick overview and answer
If you are asking How can I make concrete waterproof?, the best practical solution is to clean the surface with NC Nano Stone Cleaner, let it dry fully and then apply NC Nano Coating for Stone, Concrete & Tile. This creates a breathable, water repellent treatment that helps stop moisture and dirt from penetrating the concrete.
If you are asking What is the best material for waterproofing concrete?, a nano based impregnating sealer is an excellent choice for many domestic and professional applications. It penetrates the pores instead of forming a thick visible film, helping protect the surface while allowing the concrete to breathe.
If you are asking How to seal concrete to make it water resistant?, use NC Nano Coating for Stone, Concrete & Tile on clean, dry concrete after proper preparation with NC Nano Stone Cleaner.
This system is suitable for indoor and outdoor concrete, including patios, driveways, floors, walls, steps, paths, garages, workshops, balconies and commercial surfaces.
Why concrete needs sealing
Concrete may look dense, but it contains tiny pores and capillaries. These allow water and contaminants to enter the material. In the UK, outdoor concrete is regularly exposed to rain, frost, moss, algae, vehicle dirt, road salt and changing temperatures. Indoors, concrete floors can be exposed to food, drink, oil, cleaning chemicals and general wear.
Unsealed concrete can suffer from:
-
Water absorption
-
Oil and grease stains
-
Algae and moss growth
-
Frost damage and surface flaking
-
Dirt becoming embedded
-
Efflorescence and mineral deposits
-
Discolouration
-
Surface dusting
-
Harder cleaning
- Premature ageing
A good concrete sealer reduces moisture penetration and makes the surface easier to maintain. This is particularly important for external concrete, where water entering the surface can expand during freezing conditions and contribute to cracking or surface breakdown. Want to learn more?

What concrete sealing means
Concrete sealing means applying a protective product that reduces the absorption of water, dirt and contaminants. There are different types of concrete sealers. Some form a visible layer on top of the surface, while others penetrate into the pores.
NC Nano Coating for Stone, Concrete & Tile works as an impregnating nano coating. Instead of creating a heavy surface film, it penetrates into the concrete structure and helps make the surface water and dirt repellent. This keeps the appearance more natural and helps the concrete remain breathable.
This is important because concrete often needs to release internal moisture. A breathable treatment reduces the risk of trapping damp beneath a sealed film.

The surface must be clean, dry and absorbent enough for the coating to penetrate.
How can I make concrete waterproof?
To make concrete waterproof in everyday terms, you need to make it water repellent. Concrete can be made highly resistant to water absorption, but most breathable treatments do not turn it into a fully waterproof tanking system for structural water pressure.
For patios, driveways, floors and walls, use NC Nano Stone Cleaner first and NC Nano Coating for Stone, Concrete & Tile afterwards.
The process is:
-
Remove loose dirt and debris
-
Clean the surface with NC Nano Stone Cleaner
-
Rinse or wipe away loosened contamination as instructed
-
Allow the concrete to dry completely
-
Apply NC Nano Coating for Stone, Concrete & Tile evenly
-
Avoid puddles or uneven application
-
Allow the coating to absorb and cure
- Test by checking whether water beads on the surface
After treatment, water should remain on the surface for longer instead of soaking in immediately.
What is the best material for waterproofing concrete?
The best material depends on the application. For structural waterproofing, such as basements under hydrostatic pressure, specialist waterproofing membranes, tanking systems or professional construction solutions may be required.
For everyday concrete protection, such as patios, driveways, floors and walls, the best option is often a breathable impregnating sealer. NC Nano Coating for Stone, Concrete & Tile is designed for this type of protection.
A good concrete waterproofing treatment should:
-
Penetrate into the surface
-
Reduce water absorption
-
Repel dirt and contaminants
-
Allow the concrete to breathe
-
Avoid changing the appearance unnecessarily
-
Be suitable for indoor and outdoor use
-
Make cleaning easier
- Help reduce algae and weathering
This makes nano coating a strong choice for anyone looking for a Waterproof concrete sealant or the Best waterproof Sealer for Concrete for general surface protection.
How to seal concrete to make it water resistant
Concrete sealing works best when the surface is properly prepared. Skipping cleaning or applying coating to damp concrete can reduce performance.
Follow these steps:
-
Inspect the surface
Check for cracks, loose sections, old coatings or deep stains. Repair damaged areas before sealing. -
Clean thoroughly
Use NC Nano Stone Cleaner to remove dirt, algae, dust and contamination. -
Let the surface dry
Concrete must be completely dry before sealing. This is especially important outdoors. -
Apply the coating
Use NC Nano Coating for Stone, Concrete & Tile evenly across the surface. -
Allow absorption
Let the product penetrate the concrete pores. -
Remove excess if needed
Avoid visible pooling or uneven patches. -
Let it cure
Protect the surface from water during the initial curing period. -
Test the result
Water should bead on the treated surface.
Waterproof concrete sealant for outdoor concrete
Outdoor concrete faces the toughest conditions. Rain, frost, moss, algae, fallen leaves, mud, vehicle dirt and pollution all affect the surface.
Using NC Nano Coating for Stone, Concrete & Tile as a Waterproof concrete sealant helps protect outdoor concrete by reducing water absorption. This can help limit frost related damage and reduce dirt build up.
Outdoor applications include:
-
Driveways
-
Patios
-
Garden paths
-
Concrete steps
-
Outdoor floors
-
Concrete terraces
-
Balcony surfaces
- Exterior walls
For outdoor concrete, make sure the weather is suitable before applying. The surface should be dry, and rain should be avoided during curing.

Concrete sealing indoors
Indoor concrete also benefits from sealing. Concrete floors in homes, garages, workshops and commercial spaces can absorb oil, grease, drinks, dust and cleaning residues.
Sealing indoor concrete helps:
-
Reduce staining
-
Make cleaning easier
-
Reduce dust and dirt absorption
-
Protect against oil and grease marks
-
Keep floors looking cleaner
- Reduce maintenance effort
Use NC Nano Stone Cleaner first, then apply NC Nano Coating for Stone, Concrete & Tile once the floor is fully dry.
Concrete sealing outside
Concrete sealing outside is particularly important in the UK climate. Outdoor concrete often stays damp for long periods, which encourages algae, moss and staining. During winter, absorbed water can freeze and expand, putting stress on the surface.
Sealing outside concrete helps:
-
Reduce water penetration
-
Reduce algae and moss conditions
-
Help protect against frost stress
-
Keep patios and paths cleaner
-
Make dirt easier to remove
- Extend surface life
It is particularly useful for patios, driveways, garden paths and steps.
Why cleaning before sealing is essential
A concrete sealer works best on clean, dry and absorbent concrete. If the surface contains algae, dirt, grease or dust, the coating may not penetrate evenly. This can lead to patchy protection and reduced performance.
NC Nano Stone Cleaner is therefore an essential first step. It prepares the surface before sealing.
Cleaning first helps remove:
-
General dirt
-
Dust and surface grime
-
Algae and green deposits
-
Grease and oil residues
-
Weathered contamination
- Marks that could interfere with coating performance
After cleaning, the concrete must dry fully before NC Nano Coating for Stone, Concrete & Tile is applied.
Concrete sealing versus paint or film coatings
Some concrete treatments create a visible layer on the surface. These may be useful in certain situations, but they can change the appearance and may peel or wear if the surface is heavily used.
A nano impregnating sealer works differently. It penetrates the pores and helps protect from within the surface.
Benefits of nano impregnation include:
-
Natural appearance
-
Breathable protection
-
Reduced water absorption
-
Reduced dirt penetration
-
No thick glossy film
-
Easier maintenance
- Suitable for many porous surfaces
This makes it ideal for people who want protection without changing the look of concrete dramatically.
Maintenance after sealing concrete
A sealed concrete surface is easier to maintain, but it still needs regular care.
Maintenance tips:
-
Sweep regularly
-
Rinse outdoor surfaces when needed
-
Remove leaves and organic dirt
-
Clean oil and grease spills quickly
-
Avoid harsh chemicals where possible
-
Use mild cleaning products
-
Check whether water still beads on the surface
- Reapply coating when water begins to soak in again
Outdoor surfaces usually need more frequent checks than indoor floors because they face weather and abrasion.
Problems prevented by sealing concrete
Using NC Nano Stone Cleaner and NC Nano Coating for Stone, Concrete & Tile helps prevent or reduce:
-
Water absorption
-
Dirt penetration
-
Oil and grease staining
-
Algae and moss growth
-
Frost related surface stress
-
Discolouration
-
Premature ageing
-
Difficult cleaning
-
Surface weathering
- Long term maintenance costs
The cleaner prepares the concrete. The coating protects it.
