How to Resurface Concrete - YouTube

Resurfacing concrete.

Although concrete is one of the most durable building materials available, time, traffic

and the elements can cause the concrete surface to spall, wear and discolor.

QUIKRETE Concrete Resurfacer can provide a new, durable, wear-resistant surface on old,

worn concrete driveways, sidewalks and patios that will last the life of the concrete.

QUIKRETE Concrete Resurfacer will renew your concrete surface at a fraction of the cost

to tear out and replace old concrete slabs.

As with any concrete repair project, proper surface preparation is essential for a successful

result.

This is especially true for concrete resurfacer. Old concrete must be rigorously cleaned to

ensure proper adhesion to the new surface.

A high-strength, 3500 PSI pressure washer must be used to remove any dirt, oil, grease

or deteriorating concrete, prior to the application of concrete resurfacer.

Concrete Resurfacer is ideal for resurfacing large areas, like driveways, patios and pool

decks, but because it sets quickly, it is important to section off your work areas to

no larger than 144 square feet.

This will allow enough time for placing and finishing the resurfacer, before it begins

to set.

It's essential that control joints and expansion joints are maintained, to allow for slab movement.

These joints can usually be used to define your work area.

Weather stripping can be used to prevent concrete resurfacer from spilling into the joints.

Before resurfacing your slab, deeply spalled areas and large cracks should be repaired

using concrete resurfacer that has been mixed to a trowel-able consistency.

The repairs should be allowed to harden, before resurfacing the entire area.

To mix concrete resurfacer, a 5-gallon bucket and a 1/2 inch drill and paddle mixer should

be used.

Hand-mixing in standard concrete barrel-type mixers cannot be used for this application.

When mixing or placing concrete resurfacer, as with any cement mix, it is important to

wear safety glasses and water-proof gloves.

Measure and add 3.5 quarts of clean, cool water to the five gallon bucket, to mix one

40 lb.

bag of concrete resurfacer.

Then, begin to add the powder to the water, while mixing.

Mix for about five minutes, until a lump-free, pourable consistency is achieved.

If the mix is too thick, add water, sparingly, to reach the consistency of syrup.

If the mix is too thin, additional powder can be added.

One 40 lb.

bag of concrete resurfacer covers about 90 square feet at 1/8 of an inch thick, so a

typical 16 foot by 24 foot driveway would use about five bags of resurfacer.

Because the application process is continuous, it is always best to have a few extra bags,

to allow for any changes in thickness or waste.

Prior to applying concrete resurfacer, saturate the surface with water, and then, remove any

standing water.

Concrete acts like a rigid sponge.

Dampening the concrete will cool the slab and prevent the mixing water from being drawn

out of the material, during the resurfacer application.

You are now ready to begin the application process.

Pour the resurfacer onto the concrete in one-foot wide strips.

Then, using a long-handled squeegee, scrub the material into the concrete surface.

Working back and forth, evenly spread the resurfacer onto the slab.

After about five minutes, a non-slip finish can be applied, using a concrete broom.

Make long strokes, across the full distance of the work area, without stopping.

All broom strokes should be made in the same direction, for uniformity of appearance.

A concrete edging tool can also be used within about 20 minutes of pouring the resurfacer.

Concrete resurfacer has a working time of about 30 minutes at 73 degrees.

In hotter weather, the working time will be reduced.

Using cold mixing water and keeping the bags of concrete resurfacer shaded will help extend

the application time.

Under normal conditions, no special curing is required.

Although, in temperatures over 90 degrees, moist cure with a fine water mist for 24 to

48 hours.

Because concrete resurfacer is polymer-modified, temperatures should remain above 50 degrees,

for at least 8 hours, and should be protected from freezing for 24 hours after application.

Concrete resurfacer will support foot traffic in about 6 hours and vehicle traffic in 24

hours.
