Concrete, brick, and masonry all fail in different ways, so the right sealer depends entirely on the surface and the goal. Penetrating silane/siloxane and siliconate sealers repel water invisibly and are best for pavers, patios, and vertical walls, while film-forming acrylics add a wet-look gloss to decorative concrete. For basements you need a true waterproofer that stops liquid water under pressure. Below are our picks across all of those jobs (driveway-specific sealers are covered in a separate guide).
A pro-grade water-based acrylic that delivers a durable high-gloss wet look on concrete pavers and stamped concrete while helping lock joint sand in place. Best when you want color pop and a sealed film, not an invisible finish.
- Concrete pavers
- Patios and walkways
- Wet look / color enhancing finish
- Locking in joint sand
Pros
- Deep wet-look gloss that noticeably enriches paver and stamped-concrete color
- Water-based acrylic cleans up with soap and water and has low odor for a film-former
- Helps stabilize joint sand and resists weeds and ant activity between pavers
Cons
- Film-forming finish can turn hazy or white if applied too thick or over damp pavers
- Needs a full reseal every 2-4 years, unlike penetrating sealers that last longer
- Glossy surface can get slippery when wet unless an anti-slip additive is added
A water-based siliconate that soaks in and repels water without any surface film, ideal for keeping bare light-colored concrete patios and pavers looking natural. Choose it when you want protection with zero sheen, not a decorative wet look.
- Light or white concrete patios
- Concrete pavers (uncolored)
- Natural / invisible finish
- Water repellency without a film
Pros
- Penetrates and reacts below the surface, so it leaves no film to peel, flake, or turn slippery
- Zero-VOC and does not change the look, color, or traction of bare concrete
- Reduces water absorption, freeze-thaw spalling, and efflorescence on porous slabs
Cons
- Cannot be used on colored, dark gray, brick, or exposed-aggregate surfaces
- Provides no gloss or color enhancement, so it is wrong for a wet-look goal
- Lower coverage per gallon than film-forming acrylics on porous concrete
A breathable silane/siloxane repellent built for vertical brick, block, and stucco that keeps wind-driven rain out while letting the wall breathe. Pick it for above-grade masonry walls where you want an invisible, breathable repellent rather than a waterproof coating.
- Brick and block walls
- Stucco and CMU
- Vertical masonry water repellency
- Clear natural finish
Pros
- Penetrating silane/siloxane repels wind-driven rain on vertical brick, block, and stucco without a film
- Breathable and vapor-permeable, so trapped moisture can still escape the wall
- Zero-VOC, low odor, and non-yellowing with a long material warranty
Cons
- Coverage swings dramatically with masonry porosity, making product estimating tricky
- Water-repellent only, not a waterproofer, so it will not stop liquid water under head pressure
- No color enhancement or gloss, so it does nothing decorative for the wall
The go-to interior film-forming waterproofer for basement and foundation walls, rated to hold back water at up to 15 psi with a 15-year warranty. Best for bare masonry block or poured walls where you need a true waterproof barrier, not just a repellent.
- Interior basement walls
- Foundation and block walls
- Below grade masonry
- Stopping water seepage under pressure
Pros
- Encapsulated polymers bridge pores and stop water under up to 15 psi of hydrostatic pressure
- Backed by a 15-year waterproofing warranty when applied at two full coats
- Water-based cleanup and can be tinted, unlike bare penetrating sealers
Cons
- Requires bare, unpainted, unsealed masonry, so old paint or prior sealer must be removed first
- Two thick coats at 75-100 sq ft per gallon means it covers far less area than penetrating sealers
- As a surface film it can blister or peel if applied over a previously coated or dirty wall
A budget high-solids acrylic that delivers a glossy wet look on stamped and decorative concrete, patios, and pool decks. Best for homeowners who want an affordable, easy-to-find decorative sealer and accept more frequent resealing.
- Stamped and decorative concrete
- Patios and pool decks
- High gloss wet look
- Budget friendly acrylic sealing
Pros
- Inexpensive and widely stocked, giving a strong high-gloss wet look on stamped concrete
- Non-yellowing acrylic that enriches color on decorative and exposed-aggregate concrete
- Easy roller or sprayer application with a fast 4-hour recoat window
Cons
- As a thin acrylic film it wears and needs reapplication sooner than premium paver sealers
- Can trap moisture or whiten if applied over damp concrete or before release agent is fully cleaned off
- Glossy film gets slippery when wet unless a traction additive is mixed in

Frequently Asked Questions
- What is the difference between a penetrating sealer and a film-forming sealer?
- A penetrating sealer (silane/siloxane or siliconate) soaks in and reacts below the surface to repel water with no visible change, so it will not peel and keeps traction. A film-forming sealer (acrylic) leaves a surface coating that adds gloss and color enhancement but wears over time and can get slippery when wet.
- Do I need a waterproofer or a water repellent?
- A water repellent (like a silane/siloxane) sheds rain and reduces absorption but will not stop water pushing through under pressure. A waterproofer (like DRYLOK Extreme) forms a barrier rated to hold back hydrostatic pressure and is what you want for below-grade basement and foundation walls.
