What Types of Sealers Are Used on Interior Concrete Floors?

2017-11-06

With many Acrow-Richmond concrete sealers to choose from, it can be hard to identify which will be the right fit for your project. While penetrating, film-forming, siloxane, acrylic, epoxy, polyurethane, clear, and stamped concrete sealers can all be used indoors, you may desire a specific shine or colour that can only be offered by some sealers. This article, explores the types and features of each different sealer.

Interior Concrete Sealers

Ideally, those applying concrete sealers indoors should consider a water-based sealer over a solvent-based sealer. This is because water-based sealers have low VOCs and low odours, whereas solvent-based sealers have high VOCs and can be very odorous. However, some water-based concrete sealers do not last as solvent-based concrete sealers. 

Below we highlight some quick facts that you should be aware of before making your decision: 

Water-based

  • Not very shiny
  • Lower VOC’s and odours
  • Lower quality versions may not last as long

Solvent-based

  • Color-enhancing sheen
  • Higher VOC’s and odours
  • Have greater longevity

Avoiding VOCs Indoors

VOCs are solvents that are released into the air as sealants, chemicals, or paints dry. VOCs should be avoided (when possible) as they can cause: 

If using products with VOCs indoors, you should always open up windows to allow for air circulation, cover your mouth and nose with a respirator designed to work with organic vapours to reduce inhalation, and keep children and pets away.
