There are two kinds of concrete sealers, and you are wise to select a penetrating sealer. You are unlikely to find polyurethane caulking in hardware stores (they usually only carry silicone, latex and butyl compounds), but you may be able to find it in Home Depot (where I found Sika brand polyurethane), Lowe's or other big-box stores. It should not stick to the bottom of the crack or any other material on the back of the caulking bead.įollow this with a polyurethane caulking compound, which you will probably have to buy in construction specialty stores. The purpose of the backer rod is to keep the caulking bead no deeper than the width of the crack and to allow the caulking to stick only to the opposite sides of the crack. Push it in to a depth not to exceed the width of the cracks. But if you choose to fill the cracks, you could use the right size backer rod and carefully press it in the joints with a wooden stick, without breaking its fragile skin. It is usually not necessary to fill them with anything. Des Plaines, Illinois via emailĪ: Control joints are there to control the normal cracking of any concrete work. Would you have any recommendations for a penetrating concrete sealing product? Thanks for your time. Should I caulk these cracks?Īlso, when should I seal the new concrete? I was told by other people that the fall would be a good time to do this. I'm afraid with the freeze-thaw cycles in our area, these cracks will become bigger in time. In our area, the weather can get very cold with the snow and ice. I noticed that the concrete was starting to crack in the contraction/control joints. I had a new concrete walkway poured in the beginning of May. You've probably answered these questions before, so please bear with me. Q: I have questions about some concrete work that was just done. The person who framed the picture was right: two hooks should be used, and they should be on exactly the same level. Place the heavy hooks against the tape with the point of the nail in the center of the X's, and drive the nails in gently while pushing hard on the hooks to prevent the flaking off of the top coat of the plaster. Burlington, Vermont, via emailĪ: Here is an old trick for hanging pictures on plaster walls: Put two Scotch tape X's about 2 inches apart where you want to hang the picture. There is only one outlet inside the house on that wall, and it is low to the floor. The lines are not "inside" the wall, but are encased in metal tubes in the garage. I should mention that behind the wall we are starting with is the garage wall, which does have electrical wiring in it. She gave me heavy-grade picture hooks, but I'm not sure if it makes sense to use two as they'd have to be pretty close together. Should I be using something special? And I think we need to drill holes first, right? The person who framed the heavy painting said to use two hooks. However, the one painting that weighs perhaps 20 pounds needs to be in the center of a short wall, so if there are studs, there might not be one in the center. I purchased a stud finder, but it doesn't seem to work on these walls we used the thick wall setting. We never had plaster walls before, so I am afraid to mess them up and have gotten a couple different stories on how to hang pictures. We did see how thick the plaster walls are (I think 1½ inches or more), and a contractor said they are the better type of plaster walls - the kind that won't bow or anything like that. Q: After finally getting someone to do a minor kitchen remodel, which was not very carefully done, I have now gotten the living room painted and am ready to hang pictures.
