How to Choose the Best Concrete Sealer

When it comes to choosing the best concrete sealer for sealing your concrete, there are a few things you need to take into consider:

  • What do you want your concrete to look like once sealed? If you want your concrete to maintain an unsealed look then you want a penetrating concrete sealer. If you want a wet look, low gloss, or high gloss finish then you want an acrylic concrete sealer.
  • Why are you sealing your concrete? If you have weak or deteriorating concrete, or concrete dusting, then you want to put down a concrete densifier sealer. If you have cracking, spalling, or pitting caused by water absorption, or if you have mold, mildew, or efflorescence, then you want a water repellent concrete sealer. If you want to darken your surface or enhance it with a gloss, or completely protect the surface of your concrete then you want an acrylic sealer or a concrete coating.
  • How often do you want to maintain your concrete sealer? Penetrating concrete sealers (concrete densifiers and water repellents) require little to no maintenance for 7-10 years. Acrylic sealers need to be re-coated every 1-4 years and concrete coatings (only interior) need to be re-coated every 5-10 years.
  • What is your concrete currently sealed with? If your concrete is currently unsealed you have the luxury of choosing any concrete sealer you want to use. If your concrete is currently sealed, you need to make sure the new sealer is compatible. If your concrete is currently sealed with a concrete densifier you can reseal with a water repellent concrete sealer or an acrylic concrete sealer. If your concrete is currently sealed with a water repellent sealer you can reseal with the same type of water repellent sealer (assuming you are in the reseal window) or a solvent based acrylic sealer. If your concrete is currently sealed with a water based acrylic you can reseal with a water based acrylic, and if your concrete is currently sealed with a solvent based acrylic you can reseal with a solvent based acrylic.

How To Shop for Concrete Sealers

With so many brands of concrete sealers on the market, shopping for a concrete sealer can be quite the process. Click on the links at the top of this article to find out which products we suggest for each category of sealer you are considering. Here are a few ways in which you can determine if a concrete sealer is best for you:

  • How long as the manufacturer been in business? If the company has been in business for 5 or more years, they have proven their product can stand the test of time.
  • Does the product¬†have reviews? Reviews are great, but they aren’t always accurate. Reviews should always be considered, but only if read. In many cases, a review has to do with the product, but more often than not, the bad review has to do with application error which is out of the control of the manufacturer. Read reviews, but also research the product to see if this is an issue that could be been prevented during application.
  • Does the company have an office? If a company is based out of a PO Box, or if you can’t find any information about where a warehouse or manufacturing facility may be located, they may not be a manufacturer at all. They may be a distributor or drop ship company. You can run a quick google shop to find out if a company has a physical street address.
  • Does the company pick up their phone? This is very important. If you buy from a company that doesn’t pick up the phone, offer live support, or respond to emails, then what kind of support to you think you are going to get if you run into a problem with the sealer, or have application questions? Who you buy from is almost as important has what you are buying.
  • Does the description make sense? Is the product description simple and straight forward or do you need an dictionary to figure out what the product is and does? The use or fancy wording doesn’t necessarily mean the product is good. In many cases, it simply means they are over compensating to gain a competitive advantage.
  • Do they offer false warranties? This is a heavily debated topic. Just because a concrete sealer comes with a warranty doesn’t mean the product is good and it doesn’t mean the product will last. If you read the fine print in the warranty you will most likely find dozens of factors that void the warranty. Cashing in on a warranty, especially a sealer warranty, is usually impossible. Don’t pay more for a warranty unless you’re sure the company is going to back it up. It is better to read and be informed. Another reason we aren’t a fan of warranties is because most sealers are known to last for a very specific period of time. There is nothing that can be added to that product to extend the life. For example, silicate sealers never break down, they are permanant. Water repellent sealers last 5-10 years and acrylic sealers last 1-5 years. Epoxies and urethanes last 6-10 years. If a water repellent sealer or an acrylic sealer comes with a 10 year or lifetime warranty – it should raise a red flag.
