A professional paver-sealing project begins before the pressure washer is started and continues after the last coat is applied. Product quality matters, but the product is only one part of the result.
Seal ’n Lock’s reliability framework is: correct diagnosis + correct preparation + controlled material application + QC-tested product + final inspection.
Correct diagnosis
Walk the entire project with the customer. Identify drainage problems, unlevel pavers, damaged areas, weeds, oil, efflorescence, existing coatings and prior repairs. Ask what was previously applied and when.
Use field screening when needed. A water test can reveal beading versus absorption. A xylene test can help screen existing coating behavior. Measure substrate moisture before coating.
Correct preparation
Correct conditions before sealing. Relevel unstable pavers, address drainage, treat applicable stains or efflorescence, pressure wash thoroughly and remove loose or contaminated joint sand. Protect adjacent surfaces and manage rinse water responsibly.
Sand can be installed using the approved wet- or dry-sanding method for the project. For dry sanding, the pavers must be dry enough for the sand to move into the joints. Use the specified 20/30 sand and finish approximately 1/8 inch below the chamfer.
Controlled material application
Confirm the current product instructions, component ratio and dilution before mixing. Seal ’n Lock 1K systems typically use a 1:1 dilution for flood and finish coats. Seal ’n Lock 2K systems typically use a 3:1 water dilution for the flood coat after Part A and Part B are fully mixed, followed by 1:1 finish coats.
Apply the flood coat with special attention to the joints. Allow the coat to become dry to the touch before applying a finish coat. Additional controlled finish coats may increase barrier protection, but overapplication should be avoided. Follow current product guidance for coat limits.
PRO-Traction should be incorporated into the final coat—either mixed into the sealer or distributed using an approved broadcast method—so it remains positioned where it can contribute most effectively to the finished surface.
QC-tested product
Seal ’n Lock evaluates batches for key quality-control properties so contractors receive consistent material. QC does not remove the need for field control, but it provides a repeatable starting point for every job.
Final inspection
- Confirm the intended gloss and color enhancement.
- Look for haze, fish eyes, puddling, missed areas and uneven drying.
- Verify joints are stabilized and surface drainage is unobstructed.
- Review cure and traffic restrictions with the customer.
- Photograph the finished project and document materials, dilution and conditions.
The complete system creates reliability
When every step is controlled, the workflow becomes easier for the crew, faster to repeat, cleaner in execution and more reliable for the contractor and customer.
Next step: Use Seal ’n Lock products with the current application guide and professional training resources for a repeatable start-to-finish system.
