Everything You Need to Know
Armstrong S-462 Seal Strong 2-Part Moisture Mitigation System (SKU S-462) is a solvent-free, two-part epoxy moisture mitigation system (black Part A resin and yellow Part B hardener) that creates a moisture barrier between concrete and resilient flooring. Typically one coat fully seals the concrete. This listing is for one 6.25 L (1.65 gallon) two-part kit. Sold by the kit by Word of Mouth Floors — order exactly the quantity you need, no square-foot maths.

Key Benefits
- Suitable up to 100% RH (or 25 lbs per 1,000 sq ft per 24 hrs MVER) on porous, unheated concrete slabs.
- Typically one coat — penetrates and fully seals the substrate.
- Longer working time and faster drying — approximately 20 minutes of working time at 70°F; minimum 4-hour cure.
- Part of the Armstrong Strong System — finish with S-463 Level Strong before flooring installation.
Best Applications
Recommended for: Commercial and residential installations over porous, unheated concrete with high moisture readings, ahead of an S-463 Level Strong underlayment and Armstrong resilient flooring.

Excellent Quality & Price! I found Word of Mouth online, ordered, and after completing my install today I couldn’t be happier! They look great and are a fraction of the price of identical products at big-box stores. Highly recommend.
Would recommend this company to anyone looking to buy flooring. Very professional and knowledgeable. The flooring we bought looks great and will be contacting you for business in the future. Thanks James!
