My Choice For
The Best Concrete Sealer
For A Pool Deck

If you want to protect your concrete pool deck from spalling, pitting, and cracking, the best concrete sealer to use is RadonSeal deep penetrating sealer.

This non-slip sealer will give you a natural matte finish that'll permanently protect your concrete for years.

RadonSeal's sealer is excellent for using around salt water pools and chlorine water pools.

I use it on my customer's pool decks because it works. It densifies, hardens, and makes the concrete stronger. 


Listen to me explain why I use RadonSeal deep penetrating concrete sealer on my pool decks and watch how easy it is to apply.


My name is Mike Day, I own Day's Concrete Floors, Inc. My company installs dozens of concrete pool decks every year.

I've been installing pool decks in Maine for over 30 years. Maine is a state where we get below freezing weather in the winter and hot, humid 90 degree weather in the summer.

I needed to find the best concrete sealer for protecting my customers pool decks in this extreme weather climate. 

I came across RadonSeal sealer quite a few years ago, researched it, contacted the owner and asked him why I should use his sealer on my customer's pool decks.

Joe, the owner at that time, explained to me how his sealer works (see the scientific explanation below) and why it's so much better than using an acrylic topical concrete sealer.

He wasn't pushy or salesmen like, he was sincere, knowledgeable, and confident. That was enough for me to try it and see for myself.

I used it on multiple pool decks that first year and really liked it. But the real test was the following Spring after a cold winter with many freeze and thaw cycles.

That next Spring I had no call backs on any of my pool decks. I stopped by some of them when I was working close by and saw no damage from spalling, pitting or cracking.

For that reason, I've been using it ever since and I highly recommend it as the best concrete sealer for pool decks.


Why is this the best sealer for pool decks?

There's a lot of reasons why I like this sealer so much. 

Here's the most important one's:

  • Protects outdoor concrete from freeze/thaw damage
  • Protects exterior concrete from road salt damage
  • Permanent sealer, you don't have to keep re-sealing every year
  • Doesn't peel, flake, or wear away
  • Slip-resistant - penetrates into the concrete to seal it
  • It makes the concrete denser and stronger, hardens the surface
  • Waterproofs the concrete - expands deep inside the pores
  • Helps reduce cracking

How Often Should You Seal A Concrete Pool Deck?

Your pool deck should always be sealed. What's so great about RadonSeal's sealer is once you seal it the first time, that's it. 

You don't have to seal it again. RadonSeal is permanent, it doesn't wear off.

When you apply RadonSeal, it gets absorbed into the concrete (up to 4").

It chemically reacts with the free lime and alkali inside the concrete, expanding inside the pores and capillaries.

It forms a hard silicate material inside the concrete, kind of like injecting portland cement into the pores of the concrete.

Either spray it on like I do or roll it on, 2 thin coats, and you don't have to seal your pool deck ever again.


Is RadonSeal Easy to Apply?

How to seal a concrete pool deckSpraying with a pump up sprayer is very easy

Yes, it's very easy to apply.

Your concrete pool deck must be dry to apply it. If it's been raining, let the concrete dry out for 2 days.

Make sure it's not going to rain for 24 hours after you apply it and the air and surface temperatures are above 45 degrees during the application and for 3 days after.

Your pool deck has to be clean from dirt, mold, and mildew. Pressure wash it to clean it if you have to. (let it dry out for 3 days if you do)

There also can't be any other previous coatings, paint, or sealers on the concrete.

For best results Use a PUMP UP SPRAYER like I do in the video. You can also use a paint roller if that's easier for you to apply with.

THE BASIC STEPS FOR APPLICATION ARE:

  1.  Lightly dampen the surface with water (it helps the sealer be absorbed better)
  2. Spray or roll on RadonSeal in a continuous wet film but don't make puddles. If you do, just spread it out with a roller.
  3. Apply a SECOND coat while the first one is still slightly damp. It's ok to walk on if the first coat isn't completely dry.

A 5 gallon pail of sealer will cover about 1000 square feet for 1 coat. So you'd need 10 gallons for 2 coats if you have a 1000 sq. ft. pool deck.

As a concrete contractor I have to make sure the pool decks I install last a very long time.

A concrete pool deck is a big investment for the owner and it should be protected by the best sealer your money can buy.

After using many different brands and types of concrete sealers over the years, with many failing, some wearing off, and some making the concrete slippery, I found RadonSeal and it's been the best sealer I've used for protecting concrete.

So I've kept using it and it's what I recommend you use for your pool deck.

Make your concrete last longer, clean easier, and look better by sealing it with RadonSeal sealer.
