Application Instructions:

Apply Sentinel 145 directly to the adhesive using a mop, floor squeegee, or garden sprayer. Ensure full coverage without overapplying.
Let it soak for 10–20 minutes to penetrate and soften the mastic.
Scrape off softened adhesive using a floor scraper to minimize liquid waste and extend product coverage.
Agitate and lift remaining residue with a short-bristled broom or floor scrubber. Collect and absorb waste for proper disposal.
Final Clean-Up: Wash surface using Sentinel 317 Multi-Purpose Cleaner, allow subfloor to dry for 24 hours, and test moisture levels before re-flooring.

Note:

Use at room temperature (~70°F) for best results. Protect surrounding areas to prevent spread of adhesive and cleaner.
