Hi Touka, 900 square feet is a decent size area. If you are pouring a 4 inch slab you will need 505 bags of 80 pound quikrete. If you pour a 6 inch slab, you will need 748 bags of 80 pound quikrete. That is a lot of work. It would be a lot easier to have it trucked in.

An 80 lb bag of QUIKRETE Concrete Mix yields approximately 0.6 cubic feet. Standard slabs are typically 4 inches (0.34 feet) thick. For a 900 square foot area, 4 inches thick, approximately 306 cubic feet of concrete, or 510 80 lb bags will be needed. This is an estimate and will vary based upon waste, uneven sub-grade, etc.

Hello tinygeorge and thank you for your question.

You will need to have a raw concrete surface before adding the Quikrete 80 lb. Concrete Mix (Model # 110180). If you are working on a painted or stained surface, remove the paint or stain before proceeding. If that is not possible, paint Quikrete 1 qt. Bonding Adhesive (Model # 99) over the surface using a paintbrush. Allow to set up for 1-2 hours before pouring the new concrete.

Best wishes on your project.

Yes, QUIKRETE Concrete Bonding Adhesive is designed for use to bond new concrete, plaster or stucco to existing concrete, plaster or stucco to improve the bond. Use it to coat the existing clean, unsealed, prepped concrete surface before applying the new concrete. Note that sidewalks and driveways are standardly broom finished - the broom finish roughness provides traction when wet.

Hello Tony48, I’m Chris from the Home Depot’s how-to Community. Thank you for your question.

Each 80 pound bag makes 0.6 cubic feet of concrete.

You have a need for 12’x3’x0.5’ or 18 cubic feet of concrete.

Therfore, 18 cubic feet / 0.6 cubic feet / bag = 30 bags.

I hope this helps,
Chris.

A standard concrete slab is typically 4 inches thick. Proper placement of rebar or concrete wire in a 2” thick slab would be difficult to successfully achieve. Advantages of including rebar and / or wire mesh can include reduction of random cracking, reducing and controlling crack width, minimization of displacement and curling, and increased strength. A solid sub-base, such as compacted gravel, will help prevent erosion and slab settling.

April 26, 2013
An 80 lb bag of QUIKRETE Concrete Mix yields approximately 0.6 cubic feet of concrete. A 50 foot x 47 foot x 3.5 inch slab will require approximately 686 cubic feet of concrete, or approximately 1,143 80 lb bags. This estimate will vary based upon waste, uneven subgrade, etc. A slab of this size will require control joints to allow for movements caused by temperature changes, drying shrinkage, etc. With a slab of this size, it would be crucial that you have sufficient equipment and man power to allow you to pour the entire slab before any of the material sets. If some of the material sets before subsequent bags are poured, a cold joint will form. A cold joint is caused by the inability of the product to intermix between bags, and prevents the slab from being a single, solid mass. A cold joint may cause problems ranging from a simple aesthetic issue, to as serious as potentially allowing for water intrusion into the cold joint, which may eventually lead to concrete degradation.

QUIKRETE’s standard recommendation for posts is that the depth of the post hole should be one-half of the above-ground post height, and the diameter of the hole should be three times that of the post. If the posts are square 2.25 in x 2.25 inches, the diagonal of the post is approximately 3.2 inches, so the recommended diameter of the hole would be 9.6 inches. Holes of this diameter that are 24 inches deep, and contain 2.25 x 2.25 inch posts, would require approximately 1.5 bags per post, or approximately 53 80 lb bags for 35 posts. If the posts are round with a diameter of 2.25 inches, the recommended diameter of the hole would be 6.75 inches. Holes of this diameter that are 24 inches deep, and contain 2.25 inch round posts, would require approximately 3/4 bag per post, or approximately 26 80 lb bags. These estimates will be affected by waste, variation in hole dimensions, etc. Note that QUIKRETE Concrete Mix must be pre-blended with water BEFORE being added to the holes.

QUIKRETE Concrete Mix should not be used for applications less than 2 inches deep. For an overlay of 1”, you can use QUIKRETE Sand Topping Mix over a “painted on” application QUIKRETE Concrete Bonding Adhesive, after ensuring that the existing pad is NOT painted or sealed, IS structurally sound and HAS BEEN pressure washed. An 80 lb bag of QUIKRETE Sand Topping Mix yields approximately 0.6 cubic feet. For a 1 inch (0.083 ft) application over your 10 ft x 12 ft pad, approximately 10 cubic feet of material would be required, requiring 15-16 bags. This will vary based upon waste, uneven sub-grade, etc. The QUIKRETE Concrete Bonding Adhesive as a paint-on adhesive covers approximately 35 - 75 ft²/qt, so 120 square feet would require approximate 2 to 4 quarts, based upon application thickness and the porosity of the concrete.

It is not clear if you plan on removing the existing walkway in its entirety, or whether you simply have areas that need repairs. An 80 lb bag of QUIKRETE Concrete Mix yields approximately 0.6 cubic feet of concrete. To replace the walkway in its current dimensions would require between 8 to 9 80 lb bags. Sidewalks are more commonly 4 inches thick, which would require 17.5 80 lb bags. These estimates are approximate, and will vary based upon waste, uneven subgrade, etc. If you instead plan on repairing the walkway, depending upon the damage, different products will be appropriate for repair. QUIKRETE Vinyl Concrete Patcher is designed for making repairs to small areas of concrete surfaces which are cracked, chipped, or spalled. It is not intended to be used for deep patches or large areas. QUIKRETE Commercial Grade FastSet Repair Mortar is a polymer modified, rapid setting repair material specially formulated to make structural repairs to any concrete or masonry surface, horizontal or vertical. It can be built up to at least 1 ½” in a single application. Once you make the necessary repairs, you may consider top coating the entire walkway (while maintaining the control joints) with QUIKRETE Sand / Topping Mix. If the majority of the area will require an application that is at least 1 inch thick, it is suggested that QUIKRETE Bonding Adhesive be used to coat the clean, unsealed, prepped surface before applying the Sand/Topping Mix. If the majority of the area will require an application that is less than 1 inch thick, it is suggested the QUIKRETE Concrete Acrylic Fortifier be blended with the Sand/Topping Mix, to replace a portion of the water, before applying the Sand/Topping Mix to the clean, unsealed, prepped surface.
