with ease 5/32" is just 1/32" smaller than 3/16". My guess is that, either due to a really good hammer-drill or relatively soft or brittle surface, you drilled the holes a little too big. If the location of the holes is critical (i.e., have to be where you already drilled) then get some larger screws - e.g., 1/4". If the location is not so critical then ...

I like it and it should get rid of that trip hazard door threshold. I'd stay away from the self-leveling anything and you don't want nor should now have level anyway. As you said, you just want to bring the dips up. Self-leveling concrete/cement would destroy the porch's pitch for water to run away from the house. You just want Flat, which is not the same ...

Concrete is a mix of four things: Water Portland cement Sand Gravel The magic happens between the first two. When the portland cement gets wet, it has a chemical reaction (which makes heat) that turns it from a powder into stone. The last two are just filler materials. It improves strength, reduces cost, and greatly reduces the heat of curing, since ...

I think that you CAN use most types of fasteners usually installed with a drill but such would be unreasonably difficult! You could get a Tapcon™ screw and hit it with a hammer enough to cause a small hole, then use the screwdriver to turn it endlessly until it drills its way into the concrete. That would wear out a number of screws and take days - ...

Unfortunately I don't think you can depend on anything hand installed into concrete, if you want a good hold. Possibly ask a friend if you can borrow their hammer drill ?

If the pipe is totally encased in concrete small surface cracks would not affect. If the cracks go all the way through, like a total crack in a foundation, it could also damage the pipe. If the concrete has shifted along the crack line then the pipe is going to be damaged. The amount of damage will depend on the type of re- enforcement done when laying the ...

Vinyl cement patch is what you're probably after. It's designed to bond well and handle impacts and movement in thin applications much better than concrete or mortar. It can be feathered to a thin edge. Mix per the instructions on the package and apply with a wide putty knife or trowel. Be aware that you won't have good results spanning from one concrete ...

I have found an acid etch is about the best and easiest methods. Most masons use muriatic acid at 15-30% with water you can go stronger but this is normally strong enough to etch the surface looking at your photo 15% may be plenty. I use a 2 part epoxy made for garages , don’t go cheap or you may find where you park your vehicle the paint peeling where you ...

A hardened masonry nail can penetrate and hold in concrete... but concrete has low tensile strength. The nail might hold in a concrete wall or floor, but in a ceiling, it would likely cause a spall - a big divot - if any weight were suspended. Pre-drilling the nail hole would give a better chance of it holding. Use the nails with caution! Wear eye ...

If you dry up all the water, and then the water comes back, then you have a leak somewhere. It was probably just a coincidence that the tub overflowed and the leak made itself known at the same time. You need to find the leak.

You can get away with back buttering if you don't have a lot of areas where the porch is not level. Get a long, straight 2x4 and slide it all over the porch and determine where the high and low spots are and mark them on the floor. Your first tiles have to be set at the highest spot. Make sure they're tilted just enough to allow the rain water to run off. ...

In short, concrete takes 28 days to fully dry or cure. The rule of thumb is that you’ll need to allow the concrete 28 days of drying time for each inch of concrete thickness if the slab is under ideal drying conditions (an enclosed area with the HVAC on, meaning there’s air circulation and a low ambient relative humidity).

On the recommendation of a neighbor, I purchased a set of five molds for US$99 with free shipping. The size for my bundle was 10" x 18" x 1.5" but they have many different sizes available. The web site has been upgraded since I purchased. The molds appear to be high quality and my neighbor has nearly paved his entire yard with the casting he's done.
