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

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 remove dirt, moss, algae, and stains. Allow 48-72 hours of dry weather after cleaning before sealing. Check that polymeric sand joints are full and in good condition — if joints are empty or eroded, replenish the polymeric sand first and allow it to cure for at least one week before sealing. Any moisture trapped beneath the sealer will cause white hazing, peeling, and a blotchy appearance that's extremely difficult to fix.

Weather timing is critical in Metro Vancouver's climate. Plan sealing for late spring through early fall when you can guarantee 24-48 hours without rain after application. Avoid sealing during the October-to-March rainy season unless you have an extended dry forecast. Temperature should be between 10-30°C, with low humidity and no direct hot sun during application. Early morning or late afternoon application works best. Never seal pavers that are hot to the touch from direct sun exposure.

Choose a quality water-based acrylic sealer designed for concrete pavers. Water-based sealers are more forgiving for DIY application than solvent-based products, dry faster, and don't trap moisture as readily. Popular brands include SealMaster, Foundation Armor, and Techniseal. Expect to pay $150-$300 for sealer to cover 400-500 square feet. Apply with a pump sprayer for even coverage, then back-roll with a 3/8-inch nap roller to eliminate puddles and ensure uniform penetration. Work in manageable sections of 100-150 square feet.

The main DIY challenges are achieving even coverage and avoiding common mistakes. Over-application creates a glossy, artificial appearance and can cause the sealer to peel. Under-application provides inadequate protection. Applying sealer over dirty pavers, wet surfaces, or uncured polymeric sand causes adhesion problems. Walking on sealed pavers before they're fully cured (24 hours minimum) can leave footprints and damage the film.

Hire a professional for large areas over 800 square feet, complex surfaces with multiple levels or intricate patterns, or if your pavers have existing sealer problems. Professional contractors have commercial-grade sprayers that ensure more consistent coverage, experience reading surface conditions, and access to contractor-grade sealers. They also carry liability insurance if something goes wrong. For a 500 square foot patio, professional sealing typically costs $1,500-$3,500 including cleaning and joint sand replenishment if needed.

A properly sealed paver installation in Metro Vancouver should last 3-5 years before requiring resealing. The marine climate's persistent moisture and UV exposure gradually break down sealer films. Signs that resealing is needed include water soaking into pavers instead of beading on the surface, increased moss and algae growth, and fading of the enhanced colour that sealing provides.
