Question 1

What's the difference between penetrating and film-forming sealers for Vancouver's climate?

Accepted Answer

Penetrating sealers are generally the better choice for Metro Vancouver's wet climate because they allow moisture vapor to escape while still protecting against water and stain penetration, whereas film-forming sealers can trap moisture and fail in our high-humidity conditions.

Penetrating Sealers — The Vancouver Advantage

Penetrating sealers (also called impregnating sealers) soak into the paver surface and create an invisible protective barrier within the concrete pores. They don't change t

Question 2

Will sealer prevent oil stains on my interlock driveway?

Accepted Answer

Paver sealer provides significant protection against oil stains but is not 100% foolproof. A quality penetrating or film-forming sealer creates a barrier that prevents most automotive fluids from soaking into the concrete paver surface, making spills much easier to clean up before they become permanent stains.

How Sealer Protects Against Oil Stains

Unsealed concrete pavers are porous and absorb oil, transmission fluid, brake fluid, and other automotive chemicals within minutes of contact. Once

Question 3

What's the difference between solvent-based and water-based paver sealers?

Accepted Answer

Solvent-based sealers penetrate deeper and provide longer-lasting protection with enhanced color vibrancy, while water-based sealers are easier to apply, more environmentally friendly, and better suited for Metro Vancouver's wet climate conditions.

The choice between solvent-based and water-based paver sealers significantly impacts both the appearance and long-term performance of your interlock installation, especially in Metro Vancouver's marine climate with its persistent moisture and frequen

Question 4

Does sealing pavers change the colour permanently?

Accepted Answer

Paver sealing typically darkens and enriches the colour of concrete pavers, and this change is semi-permanent — lasting 2-4 years until the sealer wears off and needs reapplication. The colour change is not permanent to the paver itself, but it will persist for the life of the sealer coating.

How Sealer Changes Paver Appearance

Most paver sealers are designed to enhance the natural colour of concrete pavers by creating a "wet look" that deepens and saturates the existing colours. Grey pavers b

Question 5

How do you prepare pavers for sealing after removing old sealer?

Accepted Answer

Preparing pavers for sealing after old sealer removal requires thorough cleaning, joint sand inspection, complete drying, and timing the application during Metro Vancouver's dry season for optimal results.

Surface Cleaning and Preparation

After stripping old sealer (typically done with a chemical stripper or pressure washing), your pavers need comprehensive cleaning before new sealer application. Start with a thorough pressure wash using 1,500-2,500 PSI with a rotating surface cleaner attachm

Question 6

Does sealing make paver driveways slippery when wet?

Accepted Answer

Yes, sealing paver driveways can make them more slippery when wet, but this depends entirely on the type of sealer used and the texture of the pavers. The key is choosing the right sealer for your specific application and paver surface.

Glossy vs. Matte Sealers and Slip Resistance

High-gloss acrylic sealers create a smooth, shiny film on the paver surface that significantly reduces traction when wet. These sealers are popular because they enhance colour vibrancy and create a "wet look" that ma

Question 7

Can I seal my interlock pavers myself or should I hire a professional?

Accepted Answer

You can seal interlock pavers yourself if the surface is properly prepared and you choose the right weather conditions. Paver sealing is one of the more DIY-friendly interlock maintenance tasks, but success depends heavily on preparation, timing, and using quality materials.

Preparation is everything for DIY paver sealing. The pavers must be completely clean, dry, and free of efflorescence (white powdery residue) before sealing. Start with pressure washing using a surface cleaner attachment to

Question 8

Can you seal pavers during Vancouver's rainy season or do you need dry weather?

Accepted Answer

You need dry weather to properly seal pavers — attempting to seal during Vancouver's rainy season (October through March) will result in poor adhesion, white hazing, and premature sealer failure.

Paver sealing requires a minimum 48-hour dry window before application and 24-48 hours of dry weather after application for proper curing. This makes sealing during Metro Vancouver's wet season extremely challenging and generally not recommended by professional contractors.

Why Moisture Ruins Paver Se

Question 9

What happens if you don't seal interlock pavers in Vancouver?

Accepted Answer

Sealing interlock pavers is not mandatory in Metro Vancouver, but skipping it means accepting more maintenance and potentially shorter lifespan for your investment. Unsealed pavers will still function perfectly as a hardscape surface, but they'll require more frequent cleaning and joint sand replenishment in our persistently wet climate.

The primary consequences of not sealing pavers in Metro Vancouver relate directly to our marine climate conditions. With over 1,200mm of annual rainfall and 60

Question 10

How long after installation should I wait to seal new pavers?

Accepted Answer

Wait 6-12 months after installation before sealing new concrete pavers. This waiting period allows efflorescence (white powdery residue) to naturally weather away and ensures the pavers and polymeric sand are fully cured.

Why the waiting period is critical: New concrete pavers contain excess calcium hydroxide from the cement manufacturing process. When moisture contacts this calcium hydroxide, it creates calcium carbonate that migrates to the paver surface as a white, chalky residue called effl

Question 11

Does sealing interlock pavers help keep polymeric sand in place?

Accepted Answer

Sealing interlock pavers provides some protection for polymeric sand but is not a substitute for proper polymeric sand application and quality. The sealer creates a surface film that can help reduce sand erosion from wind and light rain, but it won't prevent washout from heavy rainfall or poor initial installation.

How Sealer Affects Polymeric Sand Performance

A quality acrylic or polyurethane paver sealer does offer modest protection for polymeric sand joints. The sealer penetrates slightly i

Question 12

What type of sealer is best for pavers in Metro Vancouver's wet climate?

Accepted Answer

For Metro Vancouver's wet climate, penetrating sealers are generally the best choice for concrete pavers, while film-forming sealers work well for natural stone applications. The key is selecting a sealer that can handle the region's persistent moisture, frequent rain, and high humidity levels without trapping water or creating maintenance headaches.

Penetrating sealers are the most practical choice for concrete pavers in Metro Vancouver because they soak into the paver surface and cure below t

Question 13

Should I use a wet-look or matte sealer on my interlock driveway?

Accepted Answer

For Metro Vancouver driveways, a matte or satin finish sealer is generally the better choice over wet-look sealers due to safety concerns with our rainy climate and the practical realities of driveway maintenance.

Wet-Look vs. Matte Performance in Vancouver's Climate

Wet-look sealers create a glossy, high-sheen finish that dramatically enhances paver colors and gives concrete pavers the appearance of natural stone when wet. However, this same glossy surface becomes extremely slippery when wet

Question 14

How often do interlock pavers need to be resealed in Vancouver?

Accepted Answer

Interlock pavers in Metro Vancouver should be resealed every 3-5 years, compared to 5-8 years in drier climates. Vancouver's persistent rainfall, high humidity (60-80% year-round), and over 1,200mm of annual precipitation accelerates sealer breakdown and makes more frequent resealing necessary for optimal protection and appearance.

The marine climate creates unique challenges for paver sealers that don't exist in Alberta or Ontario. Constant moisture exposure breaks down sealer films faster, wh

Question 15

Does sealing pavers prevent moss and algae growth in Vancouver?

Accepted Answer

Sealing pavers provides moderate protection against moss and algae growth in Metro Vancouver, but it's not a complete solution. High-quality acrylic or polyurethane paver sealers create a protective film that makes paver surfaces less porous and easier to clean, which does reduce moss and algae establishment — but Vancouver's persistent moisture, mild temperatures, and organic debris will still allow growth over time, especially in shaded areas.

How Sealing Helps with Moss and Algae
