Each 80 lb bag of QUIKRETE 5000 Concrete Mix yields approximately 0.6 cubic feet of concrete. The square foot coverage will depend upon the thickness of the application. The minimum allowable thickness for QUIKRETE concrete is 2”, while a more typical thickness is 4”. For a 2” application, a single 80 lb bag would cover approximately 3.6 square feet, while for a 4” application, it would cover approximately half of that (1.8 square feet). These estimates are approximate and will vary based upon waste, uneven sub-grade, etc.

Yes – you may use QUIKRETE® 5000 for a 6” thick slab. It can be used for any application requiring concrete in a minimum thickness of 1 1/2" (38 mm), such as slabs, footings, steps, columns, walls and patios.

Yes you can. You can pour this 12"+ thick if you needed to. The key to equipment pads is how much weight and how much vibration will there be, as that'll determine the thickness and the amount of reinforcing steel you need to use. It'd be wise to consult a structural engineer.

The primary reason they suggest 1 to 1.5 inches is because of the quick high strength component, pouring 6 inches is likely not a good idea.

I believe you are asking if QUIKRETE 5000 High Early Strength Concrete Mix may be used for forming countertops. Yes, it may be. You may also consider using QUIKRETE Countertop Mix, item #110680 (gray), or #110681 (tint-base, ideal for coloring), which is a flowable, high strength commercial grade product designed specifically for use in forming concrete countertops.

Virtually any QUIKRETE concrete mix is acceptable for setting typical fence posts, including the QUIKRETE 5000 High Early Strength Concrete. However, QUIKRETE Fast Setting Concrete Mix in the red bag is often the product selected, as it is sets quickly and is the only concrete mix which can be poured into the hole dry, with water then added on top.

It depends on your time schedule. If you are going to want to build the fence the next day, then the fast set mix made for fence posts is the way to go. If you can wait 2 days, the 5,000 is a good choice. But if you are going to wait 5 days before working on the fence, a standard 4,000 mix will work and is more economical.

Mixed concrete weighs approximately 140 pounds per cubic foot. To achieve 240 pounds will require roughly 1.7 cubic feet of concrete. An 80 lb. bag of QUIKRETE 5000 Concrete Mix yields approximately 0.6 cubic feet of concrete so 2.9 80 lb. bags of concrete would be required. With a 1.5 ft. diameter (18”), this will produce a height of roughly 1 foot. Yields will vary based upon waste quantity, waste, etc.

Depending on the intended weight of the stone, you should use the same amount of Quikrete. For example, the 18" diameter atlas stone has an intended weight of 240 lbs. Therefore, you should use 240 lbs of Quikrete, or three 80 lb. bags. I would recommend getting extra just in case though.

A fast setting concrete mix, such as QUIKRETE Fast Setting Concrete Mix #100450, is best to use in cold weather. For the purposes of concreting, cold weather may be considered to be weather that is below 50 dF during the day, or near freezing (32 dF) at night. It is important to take certain precautions in the cold weather: 1) Mix the concrete with water before placing the material in the hole, 2) store the bagged concrete in a warm environment before use, and use warm water to mix, 3) protect the concrete from freezing for at least 48 hours for a fast setting concrete, using plastic sheeting, insulated blankets, or other means. If these preventive measures cannot be taken, it would be best to wait for warmer weather.

Generally speaking setting up, mixing, pouring /laying cement is labor intensive as there is a time component to take into account. How much money you can save by doing a cement job yourself, is almost impossible to answer as your skill level is a major factor in the overall success or failure of such a project. Labor, product, overhead, and markup = total cost of job - usually labor is around 30% of total cost.

Do not even consider doing a hand mix with that big of a job. Seriously - anything over 3/4 yd, order a redimix concrete truck for the job. It is plain a LOT more cost effective with a redi-mix truck. Also--remember the pour has to be 1 continuous monolith slab--neaning it all needs to be in place in 1.5 hrs time. So this limits how much you can mix using a mixer.

If there is mortar between bricks that you need to repoint, using QUIKRETE Mortar Mix would be appropriate, as this product does not contain large aggregate like the QUIKRETE 5000 Concrete Mix does. If you need to repair parts of concrete that have broken off of the chimney, QUIKRETE Quick-Setting Cement would be appropriate, as it can be used for both horizontal and vertical repairs, and can be sculpted as it sets.

Hi BK11,

For a chimney repair if you are re-pointing, or repairing the flue,
you should use a high strength motor mix.

Concrete mix has gravel and will not work well for chimneys.

Hello Pete'

It requires 45 bags of 80 pound quikrete to make up a cubic yard. So 3/4 of that would be 33.75 bags. A little advice would be to always add at least 10% just in case because you don't want to run out in the middle of your pour. You can return any extra when you are finished. I am wondering if your 2nd step will be twice the depth and your third step 3 times the depth, depending on how you form it up?

An 80 lb. bag of QUIKRETE 5000 High Early Strength Concrete Mix yields approximately 0.6 cubic feet of concrete. ¾ cubic yards equals approximately 20 ¼ cubic feet of concrete, which will require approximately 34 80 lb. bags of concrete. Based upon the dimensions of the set of steps you provided, if we are envisioning your project correctly, it will require under 12 cubic feet of concrete, or approximately 20 80 lb. bags of concrete (“first step” 0.33 ft. x 5.9 ft. x 1 ft = 1.95 cubic ft., “second step” 1 ft. x 0.66 ft. x 5.9 ft. = 3.89 cubic ft., “third step” 1 ft. x 0.99 ft. x 5.9 ft. = 5.84 cubic ft.). Yields are approximate and will vary based upon waste, uneven sub-grade, etc. Please contact the QUIKRETE Technical Center at 1-800-282-5828 to discuss if you feel that we are not correctly envisioning your design.

Would like to resurface two areas: Sidewalk and driveway. Both surfaces are eroded and rocks are now more predominant on the sidewalk primarily because of years of washing moss off of it.

Is this the right product?

If so, would adhesive be required prior to pouring topping?

What would be the recommended depth/height for each (sidewalk, driveway)?

Can I utilize an electric mixer (barrel type) to mix the concrete rather than mixing in a 5 gallon bucket?

QUIKRETE 5000 Concrete Mix would be acceptable if you wanted to add a minimum of a 2 inch thickness to the driveway or sidewalk. If a topping of approx. ½” to 2” is desired, QUIKRETE Sand Topping Mix #1103 would be a good match. Blend with QUIKRETE Concrete Acrylic Fortifier for applications less than 1”, OR apply a coating of QUIKRETE Concrete Bonding Adhesive to the existing sidewalk / driveway prior to applying the Sand Topping Mix for applications thicker than 1”. The Sand Topping Mix should be mixed in a barrel type concrete mixer or mortar mixer. Please contact the QUIKRETE Technical Center at 1-800-282-5828 for more detailed advice.

What you need is Quikrete CONCRETE REPAIR & REHABILITATION PRODUCT

Old concrete must be rigorously cleaned to ensure proper adhesion of Concrete Resurfacer to the old surface. Follow these easy steps to prepare the surface:

Manual Cleaning of Debris from Surface
• Wash, sweep, scrape, chip or grind the surface to remove loose concrete and foreign materials such as paint, greasy residue, algae, mildew or other materials which may be stuck to the old surface

Pressure Washing
• Clean the surface using a 3500 psi (24 MPa) pressure washer

NOTE: This step is essential in order to ensure a proper
bond is achieved.

• Follow pressure washer manufacturer’s instructions as to safe operation and effective use
• Hold the wand a few inches from the surface to strip away all foreign and loose materials

Penetrated oil or grease stains can be removed by acid washing, detergent washing and bleaching, following manufacturer’s instructions. Acid washing can damage the existing concrete if not performed properly. Be sure to rinse thoroughly with water to remove traces of cleaning solutions. Incomplete rinsing will interfere with performance of the Concrete Resurfacer.

When taking small portions of QUIKRETE 5000 Concrete Mix from the bag rather than using full bag quantities, dry mix the full bag before doing so, as material may have segregated during handling. As an example, 10 lb of QUIKRETE 5000 will require approximately 1.5 to 2.5 cups of water. Use the minimum quantity of water that will produce concrete that is place-able. Note that it is not recommended to use concrete in thicknesses less than 2” due to the aggregate it contains.

QUIKRETE Sand Topping Mix blended with QUIKRETE Concrete Acrylic Fortifier #8610 replacing a portion of the water content, for an application <1” thick, or after a painted on coat of QUIKRETE Concrete Bonding Adhesive for an application between 1 – 2” thick, would be appropriate to use as a topping over the entire porch to fill in “unlevel” places. Note that the application must be sloped slightly away from house to allow water to run off in the rain. QUIKRETE 5000 High Early Strength Concrete would not be recommended, as it should never be placed less than 2” thick in any area due to the gravel it contains.
