Failed Sealer Stripping FAQs
Review common questions about the method, included scope, preparation,
and conditions that can change the result.
Can all failed sealer be removed completely?
Complete removal is not promised. The written stripping policy defines successful included performance as removal of 80% or more of the visible failed sealer across the project area. Product type, layers, porosity, repairs, edges, low spots, texture, and material condition influence what remains; work beyond that included threshold requires a separately approved scope.
Why does the surface look different when wet?
Moisture can temporarily change the appearance of haze, trapped whitening, coating failure, and the underlying pavers. Both wet and dry observations are useful.
Can the surface be resealed right after stripping?
Not automatically. Residue, moisture, weather, repairs, and product compatibility need separate review before another application.
Will joints be affected?
Corrective preparation can expose or disturb existing joint conditions. The likely impact should be discussed as part of the scope.
Is a white or cloudy appearance always failed sealer?
No. Failed coating, trapped moisture, efflorescence, and other surface conditions can look similar. The pattern, existing layers, moisture, drainage, and a test area may be needed before the cause and next step can be scoped.
Why might Clean Master test an area before stripping?
A test area can show how the coating and paver respond, reveal substrate sensitivity, and help define likely removal limits before a broader corrective scope is set. It cannot predict every part of the installation exactly.
What history helps with a failed-sealer evaluation?
Product names, application dates, receipts, contractor history, prior spot repairs, and wet and dry photos are useful. Unknown products or multiple layers can limit what can be concluded before testing.
Why must the failure cause be reviewed before another sealer is applied?
Trapped moisture, incompatible products, residue, drainage, contamination, or substrate conditions can remain after the visible coating is disturbed. Applying another product before those factors are understood can repeat or worsen the appearance problem.
Is stripping covered by the paver-sealing warranty?
No. The written Warranty & Coverage document excludes stripping projects from the paver-sealing warranty because the prior coating failure and underlying surface conditions existed before Clean Master’s corrective work and full removal is not always achievable.
