What is a penetrating concrete sealer? Penetrating sealers retain a natural-looking finish whilst protecting the concrete surface from water, stains and contaminants. These sealers penetrate into the capillaries of the concrete to form a long-lasting, durable barrier of protection against the ingress of water-borne pollutants and salts.
What is penetrating sealer? A penetrating sealer is a sealer that penetrates deep into the surface of the concrete or masonry where it chemically reacts below the surface from within the pores. Penetrating sealers do not leave behind a visible surface film, and most of them will not change the look or color of the surface.
Are all concrete sealers penetrating? There are five main types of penetrating concrete sealers: Silicates, Silanes, Siloxanes, Siliconates, and Fluorinated materials. … Surface should also be sufficiently dry though as well as porous to be a candidate for applying a penetrating sealer.
How do you apply penetrating concrete sealer? Apply using a standard pump sprayer with an adjustable spray tip or apply using a standard ⅜” nap roller. Choose the best applicator for the size of the project and texture of the concrete. Do not pour the sealer directly on the surface or allow to puddle.

Use a standard circular saw, equipped with a corundum or diamond blade, for small tasks. For slabs, it’s best to cut through the top inch, then use a sledgehammer to break off the rest. The jagged edge left below the cutting line provides a good rough edge for the new concrete to bond to.
How long to park on new concrete?
Your new concrete is designed to reach 90% of its full strength potential after 7 days, so feel free to drive your personal vehicle on it then.
