Resurfacing concrete is the process of applying a resurfacer to a concrete slab or structure that is cosmetically damaged, but in otherwise perfect condition. A resurfacer is essentially a form of cosmetic finish. It is not a repair product and will not fix widespread damage to the structure.
If you are planning a concrete driveway restoration or if you have a concrete slab that has sustained damage from road salts, applying a coating of resurfacer can effectively renew the surface.
Does concrete resurfacing last?
Resurfacers may not correct deep cracking or heaving, but they can hide flaking from everyday wear and tear as well as small pits from spalling. Because of its strong bonding qualities, concrete resurfacing can last for a long time. A properly resurfaced concrete can last anywhere from 8 to 15 years.
To ensure the longevity of your resurfaced concrete structure, take the time to prepare properly, apply the resurfacer correctly according to manufacturer guidelines, and give the resurfacer ample time to cure.
How to Resurface Painted Concrete
Although concrete is a very strong and durable material, it is not exempt from the effects of time. Concrete can get damaged by cracks or pits, especially concrete structures that were not mixed well before getting poured.
If you have an old painted concrete structure that you are thinking about resurfacing, here are the basic steps that you should follow:
Strip old paint
For resurfacing concrete to stick, the surface should not have any finish or paint. Thus, it should be cleaned before the resurfacer is applied. This can be tough to accomplish since painted concrete typically has a protective surface. You can try pressure washing for outdoors areas such as if you are planning on resurfacing concrete porch and steps. Be careful since the water stream can damage the concrete. You can also use a chemical paint strippers, but they are usually toxic so always handle them with care.
To ensure a smooth resurfacing process, repair any visible pits or cracks. Use resurfacing concrete for this step. Mix water with a small amount of resurfacing concrete. Using a trowel, spread the mixture over the damaged areas. Let it completely set for a couple of hours.
Mix and spread
If you are working on outdoor areas such as walkways, fill in any joints with weatherstripping. Saturate the concrete with water, but not so much that you’ll see puddles or standing water. Mix the concrete according to the manufacturer’s instructions. Pour the resurfacing concrete over the old one.
Use a finishing trowel or a long-handled industrial squeegee to smooth the surface. If you want a smooth surface, continue using your tools. However, if you want some texture, use a brush or push broom for a brushed surface. Don’t forget to remove the weatherstripping from joints before the concrete has completely set.
How To: Resurface a Concrete Driveway
One of the top reasons why homeowners choose concrete as a driveway surfacing material is its durability. However, over time and given enough foot and vehicle traffic, your concrete driveway can start showing signs of wear and tear. Instead of completely ripping everything out and starting again from scratch, you can try out concrete resurfacing.
Before you start the process, always make sure that you are working under favorable weather conditions. Concrete resurfacer should never be applied during cold weather. As much as possible, work in a shaded area or where the sun’s glare isn’t as strong. Furthermore, check the weather forecast to ensure that it won’t rain at least 8 hours after the application.
Here are the basic steps that you need to follow:
Clean and prepare the surface
Remove any loose debris through pressure washing. If there are surface stains such as oil, paint, or tree sap, apply a sealer over the stain. Otherwise, the stain will most likely bleed through the resurfacing layer.
Protect the expansion joints
Protect them with duct tape or weatherstripping before applying the resurfacer.
Saturate the surface with water
Make sure the remove any standing water from the surface.
Mix and apply one bag of resurfacer
Mix one at a time. Pour a small amount on the surface, then immediately begin spreading it evenly with a light, long-handled squeegee, brush, or trowel. Always work in segments.
If it needs a second coat, let the first coat dry first for 2 to 3 hours before applying.
Give the resurfacer enough time to cure. Wait 8 hours before you walk on the surface and at least 2 days before you drive on it.
