ULTRA RECON Smoke Odor Sealer with OdorLock Plus technology is water based and does not contain flammable solvents.

This multiphase technology provides one coat odor control on most surfaces and continues to block odors even with seasonal changes in temperature and humidity. ULTRA RECON Smoke Odor Sealer (Ultra SOSTM) is your final step to encapsulate residual odors typically found on fire damage restoration projects. PRODUCT APPLICATION Apply ULTRA RECON Smoke Odor Sealer generously and uniformly by brush, airless spray or roller. Apply one coat of ULTRA RECON Smoke Odor Sealer and ensure that the finished surface is properly sealed. Twocoats may be required on some porous or heavily stained surfaces. Topcoat floor applications when foot traffic or heavy storage is expected. ULTRA RECON Smoke Odor Sealer is tintable up to 2 oz. of universal liquid colorant per gallon. Can be directly applied to wallboard, sheetrock, wood, masonry and concrete. Ferrous metals may require a DTM primer to prevent flash rusting.

BLOCKS REOCCURANCE of new mold or mildew stains. Instead of buying and using two products, our team of product engineers found a way to SAVE YOU TIME AND MONEY by combining two necessary features into one awesome bottle! Our lab tests show that 303 inhibits new stains for up to 30 days! Defeat the problem and control it. It's a mould and mildew killer folks.
SAFE ON ALL SURFACES that can withstand being dampened. This includes metal, tile, grout, vinyl, fiberglass, seats, fabric, sealed leather, trim indoor, outdoor, marine, deck and more! REMOVE unsightly black, green, and white stains from your bathroom, kitchen, or boat and keep them from re-occurring.
WORKS QUICKLY so you don't have to spend your day cleaning. Unlike some instant "miracle" products that claim to need no scrubbing (spoiler alert: it's just bleach), you will need to agitate tough spots and then wipe them dry - but it's a small tradeoff to make so your home or boat doesn't smell like chemicals.
YOUR SATISFACTION IS OUR PROMISE - 303 products have been setting the standard in the boating industry for over 25 years, and we stand behind everything with our name on it. 303 Fabric Guard and Aerospace Protectant are endorsed by Sunbrella, and our entire line is professional grade and backed by our happiness guarantee: if you don't like it, let us know and we'll make it right.
