Projects with 1 Product: How to Use Sakrete® Sand Mix Topping & Bedding Mix


Share:



Don’t be fooled by the words sand mix. Sakrete Sand Mix Topping & Bedding Mix is actually a quality mixture of sand and cementitious materials; it is perfect for mortar beds under tile or paver stones, and for creating a concrete overlay on an existing patio or stoop. So when you need a mortar bed that is up to 2” thick, we can help you get the job done.

Save a few trips to the home improvement store with the use of just one product. Here are four ways you can use sand mix on your next job.


Bedding mix for pavers

It’s the season for laying pavers. Not only do they look great, but pavers are a huge trend right now to create a more stylized look. Sakrete Sand Mix Topping & Bedding Mix is your answer to all of these projects. It locks in pavers for the perfect outdoor haven that is built to last.

Here’s how to do it: Stake out the area where the pavers are to be placed. Cut out and remove all soil, grass, sod, etc. to allow for desired finished height of pavers. Place a layer of compacted sand about 2” (50 mm) thick. This layer will serve as a base for the sand mix and failure to completely compact sand will cause pavers to shift and settle. Place a 1” (25 mm) layer of mixed Sand Mix Topping & Bedding Mix onto the sand and set the pavers into the mix. Use a level to level them as you move forward.

After placing the pavers, fill the joints with additional Sand Mix Topping & Bedding Mix. Sand Mix can be applied to joints using a grout bag. Be careful not to allow Sand Mix to dry on pavers as this will cause staining. The same procedure can be used over an existing properly prepared concrete slab. For an enhanced bond, use Sakrete Bonder & Fortifier as the brush-on primer or admixture.


Creating a mortar bed for a shower installation

Here’s how you create a mortar bed: Before building the mortar base ensure that the substrate that the mortar bed will be placed over is structurally sound and has the ability to support the weight of the mortar bed and the remainder of the project. Like with any job getting the base correct is essential. In this case you need a good solid mortar bed to support everything. Sakrete Sand Mix is a prepackaged cement mix ideally suited to this application. Mix to a dry pack consistency and install the sand mix in accordance with the Tile Council of North America’s guidelines and ANSI specifications particular to your shower floor.


Concrete overlay

On a project with rough, worn concrete? Looking at a driveway that’s seen better days? You got it, Sakrete Sand Mix Topping & Bedding Mix can be used as a concrete overlay.

Give a slab a refresh: Remove all loose and foreign matter or materials such as sealers, paints, curing compounds, or glues that will interfere with bonding. The existing substrate must be sound, solid and clean. Place forms to required finished height and to contain the material being applied. Dampen concrete surface bringing it to a Surface Saturated Dry (SSD) condition before application of the material. Mix a small amount of material with water to make a slurry consistency. Brush the slurry on the surface to be overlaid.

For an enhanced bond use Sakrete Bonder & Fortifier as the brush-on primer or admixture. Place and consolidate the mix. Using a straight edge, strike the surface by rodding back and forth to level with the top of the forms. Use a float to remove surface imperfections and a jointer tool can also be used at this time. Expansion joints should be honored and placed every 8 ft x 12 ft (2.4 x 3.7 m) in each direction and must be full depth of overlaid Sand Mix. Allow mix to stiffen until thumb print hard and the surface water has evaporated. Stiffening time will vary with weather conditions. Use a steel trowel or a broom to achieve the desired finish.


Crack repairs deeper or wider than 1”

You’re on site for one more quick repair: a crack deeper or wider than 1”. Depending on the crack, you can use the same Sakrete Sand Mix Topping & Bedding Mix that you’ve been using.

How to use Sand Mix for crack repair: Use a hose with a strong stream of water to dislodge and clean debris from the crack and allow the water to soak in. The surfaces should be brought to a SSD condition before the application of material. For enhanced performance, prime the substrate using Sakrete Bonder and Fortifier as the brush-on primer prior to the application of the material and allow to dry or mix a small amount of material with water to make a slurry consistency.

Place the mixed Sakrete Sand Mix Topping & Bedding Mix into the area that is being repaired and consolidate using a trowel. Smooth surface with a trowel to the same level of the existing concrete slab.

    Matthew, when mixing you will need to follow ASTM 476 which falls under ASTM 1019. This requires a slump up to 8 to 11 inches. Keep in that this will drastically effect your strength of this material. The product may only reach 2000 to 2500 psi. This may not meet any local specifications if you have requirements that you have to meet. You can also consider our sister company Amerimix for a core-fill grout. They have a 3000 and a 5000 psi mix that is made for core-filling.

    What is the water ratio of using to fill masonry block cores? The mixture on the bag is not loose enough for this purpose. Need a really high slump to avoid air pockets.

    Issis, repointing will be fine with the Type S Mortar Stucco. As far as a smooth surface underneath, as long as the bricks are fairly even, most people would just use an unmodified thinset on the backer board. Trowel it on the backer board, place the board against the wall and then screw it in place. The unmodified thinset will fill the gaps an cavities between the wall and backer board.

    I have revealed an old (1964) exterior brick wall which is very poorly pointed / mortared, so that they are many gaps. I've read that filling in the gaps with newer, stronger mortars can create problems. I purchased a Sankrete Mortar-Stucco mix to use with a mortar bag to fill in the gaps. I then want to smooth out the wall before covering it with insulation, etc. I would like smooth coat product to strengthen the wall as well and provide an even, finished surface. I will be insulating over the surface, attaching cement board and tiling for a shower. Which product would be best for the smooth coat over the bare, newly pointed brick?

    Kyle, the stain that you have on the pavers is cement. The Sand Mix should be mixed and then installed in the joints. You can try using a 50/50 mix of vinegar and water on an inconspicuous paver. Scrub the pavers with the vinegar mix using a stiff plastic bristle brush. Then immediately rinse thoroughly with water and allow it to dry. Once it is dry you should be able to tell whether or not this is going to work.

    I used this product to fill in my paver driveway between all of the cracks. After brushing and blowing away the excess sand that was on top of the pavers I sprayed it with a hose. The next day my whole driveway was extremely chalky and white. How do I get rid of this white Haze?

    Slappy, if you mix it to a dry-pack consistency then you should be able to tile it a soon as the material is hard enough to support your weight while tiling the floor. Usually, around 12 to 16 hours and you should be able to tile the floor.

    How long does this need to set before I lay tile over it for a walk in type shower

    Kirk, before you start anything you will need to do a moisture test on the floor. The results of this test is going to give you a starting point. If there is enough moisture coming through the floor it will cause both of those applications to fail. Once you get the results, if there is too much moisture, then you will need to apply a moisture guard material which we do not have in our product line. Now if the results are fine and you decide to lay tile, consult the manufacturer of the thinset about how long you need to wait before putting their thinset over fresh concrete. If you go with the floating floor and you want to seal, then you will need to wait at least 28 days before sealing.

    I have a concrete basement that i want to finish. Whoever poured the floor didnt make it level. There are low sections everywhere. I want to use this to level up the floor in these low sections. I then either want to lay down ceramic on top of this or a floating floor. Question; If i choose tile how long would i have to wait. If i go for floating floor. Would i have to treat or coat before putting down floating floor, and how long would i have to wait.
