    Lakehouse, you are going to want to wait at least 7 days before setting the tub. The longer the better.

    I need to pour a concrete slab for a hot tub. I got the high strength (4000 psi) concrete but it says it will reach full strength in 28 days. How long til it’s cured enough to place the tub?

    RetiredInmaryland, a lot of contractors are going to disagree with what I am about to say, however you should not pour the material in the hole and then the water. It will not set up properly and it will not last as long as it should. If you use a concrete mix you will have to mix it in advance and then pour it around your fence. You are correct about having to support the post while it sets. The best and easiest way to handle this project is the Fast Setting Concrete Mix. Prepare your holes and place the post. Then fill the hole 1/3 full of water and pour the Fast Setting Concrete Mix around the post until you have the hole full. If you have dry material a your reach the top then you can add more water. This is the only material that we have in our line that can be placed in a hole, with water, without mixing it. The Fast Setting Concrete Mix will also set up quick enough for you to hang fencing the same day. Set all of your post and go take a lunch break. When you come back your should be able to start hanging the fencing. If you have a gate, give it 24 hours before hanging it be cause of the stress it would put on the post.

    I'm putting up a wooden fence. 6x6 posts. 5 feet above ground. The soil is sandy. My local lumber yard guy is telling me to use sakretes high strength concrete mix. 4000psi. They were also telling me that I could pour dry and mix in the post hole. I though I should be using quickest for my posts, so that I would not have to support it while it sets. Any thoughts

    Duck, our regular High Strength Concrete Mix is 4000 psi, the 5000 Plus is 5000 psi, and the Maximizer Concrete Mix is 5500 psi. You can using any of these mixes for your application. They can be poured as thick as you need the footers to be. Check with your local building code requirements and see what they have to recommend as far as thickness of the footings. When dealing with that kind of point load it is always better to be safe than sorry. As far as the anchor bolts, you can drill after 7 days or it may be easier just to make a template of the base of your lift and use anchor bolts that you sink into the concrete after pouring. Then no drilling necessary.

    I want to pour footings for a two-post car lift. The manufacturer says that I need at least 3000 psi concrete and at least four inches thick. However I want to go stronger and deeper, probably at least six/eight inches. The footings will be 24" square. Please suggest what Sakrete I will need and how much water I'll need to mix it. I will also need to drill holes in it to install anchors, I have an old wheel barrow that I can mix it in. Thank you

    Rose, it really depends on what you are trying to do. If you are using a walker maker which has the stone shapes in it and you need a material to pour in to make a stone walkway, then the high strength concrete mix will be sufficient for that application. If you have a mold that you are pouring individual stones with, then you have to be careful that the mold does not have intricate details in it. The concrete mixes have stones and you will not be able to pull the fine details from a mold. But the 5000 Plus may work better in a molding application, however keep in mind that it is not manufactured for this type of use. So trial and error will be your biggest issue. I would purchase 1 bag and see how the material works for what you are trying to do.

    Kevin, our biggest concern would be the smooth surface. If you apply your bonding agent and scratch coat to a smooth surface you will run the risk of delamination. You need a surface profile of no less than a 3 to 4 CSP. You also need to make sure that you have 100% of the paint off of the surface. Paint is a definite bond breaker. The Sakrete Stone Veneer Mortar is the material that we use to apply veneer stones with and they cannot exceed 9 lbs in weight or your will need mechanical fasteners to hole the stones in place. The High Strength Concrete Mix can be used to pour the window seal if the thickness is 2" or greater.

    I used a cup grinder to clear the painted surface and get back to the concrete block on an exterior wall of a split level ranch. This is the exterior wall to a heated space in upstate New York. I plan on installing Eldorado brand composite stone veneer on that wall. I think I'm ok to apply a scratch coat directly to the concrete block. Because the cup grinder changed the surface profile by making it smoother I'm planning on using a bonding agent to help with adhesion of the scratch coat. I also have an inset basement window that I plan on making a mold and pouring a concrete sill to fit the ledge under the window. Which of your products do you think would best suit my projects? Do you advise a different approach?
