What is the best concrete sealer for an outdoor patio?

You need to use the best concrete sealer. Sealing your concrete patio will keep the patio looking great for many years. A concrete sealer improves the natural appearance of you concrete surface.

 What are the best types of concrete sealants available?

Clear Concrete Sealants

The best concrete sealers fall into a number of categories

1. Penetrating Sealers

a) Penetrating Silicone Sealers – provide protection without changing the appearance of the concrete. Protects by forming a lasting barrier just below the surface that prevents water penetration. Most are permeable, allowing moisture to breathe out.
b) Saturant Sealers – used like a flood coat, the dry concrete is allowed to penetrate. These work on a similar basis to Silicone Sealers.
The main difference is that a saturant reacts with the surface to permanently waterproof, hardens and preserves the concrete/masonry surfaces, mortars,  and most natural stone.

A couple of examples of a saturant are SealTight and Ultra Masonry Block Sealer, both of which will waterproof, harden and protect the masonry surface
The benefits of SealTight Penetrating Clear Concrete Sealer are seen below, applied using low pressure spraying.

Where you have really porous masonry, eg, Block work, then use Ultra Masonry Block Sealer. To learn more

2. Film or Membrane Sealers

a) Best acrylic concrete sealers – can be used for indoor or outdoor applications. The disadvantage is that they require regular re-application.
b) Best Epoxy concrete Sealers – can be very effective. The disadvantage is that they do not have the same properties as the masonry service, so they may be more prone to delamination.
Epoxy sealants are usually solvent based, require a primer, as epoxy requires something to adhere to. All concrete surfaces have residual water, and adhesion can be a problem
c) Polyurethane Concrete Sealers– normally not used where left exposed to sunlight due to UV being a problem.

3. Cementitious Trafficable Sealer

The advantage of cementitious products such as Drizoro Maxseal TRAFFIC is that they can prevent water from lifting the membrane from either side

Drizoro Maxseal Traffic is not a clear sealant. Best concrete sealers as it is completely trafficable and will cover cracking and withstand water pressure from above or below.

So if you are searching for the best driveway sealer for concrete to waterproof your patio or driveway, then you need to make sure you use the right material for the ideal finish and best protection of the masonry. The best water-based concrete sealer will depend on the project where it is to be used

Concrete Sealers are the Best.

According to Wikipedia, coatings are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.

Research from major concrete authorities, including the American Concrete Institute, Portland Cement Association, and the National Ready Mixed Concrete Association, confirms that most concrete damage is attributable to surface moisture intrusion. The most pervasive form of concrete damage is surface scaling from freeze/thaw.^{[citation needed]} Other forms of damage include alkali-silica reaction (ASR), chemical intrusion, and corrosion of steel reinforcements.

Once the surface is waterproof, it is also oil resistant concrete sealer covershield
