Before authorizing a future recoat, gather the existing product and application records, then ask the proposed product’s maker or a qualified applicator to confirm compatibility and any professionally scoped preparation or removal in writing. If the old treatment cannot be identified from records, mark it unknown; do not infer it from appearance or water beading.
Collect any existing product name or container information, invoice, application date, contractor record, known prior coatings, and photos already on hand. If a record is missing, say so rather than guessing what is on the concrete.
Foundation Armor’s SX5000 WB identifies unsealed concrete or masonry as its substrate and cautions against prior sealers/coatings, including recent water-repellent or film-forming treatments. This professional-use example identifies neither your treatment nor compatibility; it is not a recommendation or universal rule. SX5000 WB Technical Data Sheet.
Do not treat an aged water-repellent as compatible based on narrower wording; the sheet also cautions against prior treatments. Ask the selected product maker or qualified applicator to consider the known history and proposed product in writing; unresolved compatibility remains unresolved until confirmed.
Ask the responsible professional to state which product and current documents apply, what existing conditions and prior treatments are known or unknown, and whether any preparation or removal is proposed and included. Request exclusions, who is responsible for unresolved compatibility, and product-specific care information for later; do not treat this example as a lifespan, maintenance interval, warranty, or performance promise. Do not test, wash, strip, etch, or apply a product to identify or prepare the surface yourself.
