How Close To Edge Of Concrete Can You Drill

Tips for Concrete Fasteners and Masonry Screws

No matter which trade y'all're in, eventually you lot're going to tackle a project that requires fastening to bricks, blocks or solid physical. There are dozens of specialty masonry fasteners on the market to assistance you end those projects. Here we'll show you which fasteners work all-time for various projects and share some tips for quick, easy and long-lasting fastening solutions.

Don't Drill likewise Shut to Edges

Two mistakes you actually want to avoid are busting off a chunk of a concrete stair step and cracking the corner of a patio slab. To avoid these disasters, don't drill any closer than iv in. from the edge. If there's no other pick, turn off the hammering action on the drill. Also, avoid wedge-blazon anchors. They exert a ton of outward force per unit area, which could literally "wedge" the concrete apart.

2 / 13

Blow Out the Dust

If drilling dust is left in the pigsty, it can prevent the fasteners from existence driven all the mode in. And so remove information technology with a vacuum or blower. A baby's ear syringe (virtually $5 at any drugstore) works great for this and doesn't accept upward much room in a toolbox. Just shove information technology into the hole and puff out the grit.

Drill Correct Through the Wood

Masonry drill bits will besides plow through wood, so don't be afraid to drill correct through the wood and into the wall or slab. That makes it a lot easier to get the furring strip, or whatsoever y'all're working with, exactly where you desire it. Drill one hole and install that fastener first. (You lot'll have better luck holding the lath in place if you drill the first hole toward the eye.) Then go back and drill the rest of the holes and install those fasteners.

Use Panel Adhesive on Foam Insulation

When you're fastening cream boards to a concrete or block wall, make sure you use a construction adhesive that'southward particularly designed for cream. Regular construction adhesive can melt through the foam, causing your panels to autumn off x minutes later y'all put them upward.

Notation: You may desire to waterproof the walls start, and if so, your local building codes may require you lot to seal all the seams. Cheque with a local edifice official for those details.

Minimize Masonry Fastening

Fastening to masonry isn't all that difficult, simply fastening to forest is easier; that's why nosotros attach drywall to furring strips instead of directly to concrete walls. For projects that require a agglomeration of fasteners, like a column of shelving, install strips of pressure-treated wood with a couple of fasteners, and attach the shelf brackets to that. You lot'll save the expense and drudgery of all those extra masonry fasteners.

Don't Drill Into Brick

Whenever you install a lightweight item like a downspout on brick, always drill into the mortar joints instead of the brick face up. The brick is more probable to crack, and if the downspout ever needs to be moved, patching a pigsty in gray mortar is a lot easier than trying to lucifer the colour of the brick. Too, always install plastic anchors considering metal anchors are more than likely to crack the mortar when they expand.

Pound on the nut

We recommend sleeve anchors for heavy-duty projects. To install them, all you demand to do is drill a pigsty, tap them in and then tighten the nut. Don't tap directly on the bolt or y'all could harm the threads, making the nut almost incommunicable to remove and reinstall. Loosen the nut so it extends slightly beyond the bolt to protect the threads, and then tap on the nut instead.

What Yous Should Know Near Concrete Screws

Using physical screws is fast and easy—you lot just drill a hole and screw them in the same equally a wood screw. They work great for lite- to medium-duty tasks similar fastening shelving brackets, plumbing straps, electrical boxes and furring strips. Concrete screws don't work well on quondam, crumbling concrete. And they lose much, if non all, of their holding power when they're removed and reused in the same pigsty, so if you lot exercise have to pull ane out, try to drill a new hole in another location.

Hydraulic Cement Prevents Dandy

When yous're fastening posts, poles, big bolts or rebar to physical, drill an oversize hole and make full it with hydraulic cement. Hydraulic cement creates an extremely strong and weatherproof bail. It as well holds upwardly to repeated movement, which is why professional metal railing installers use it to ballast posts.

Hydraulic cement comes in a pulverization grade and needs to exist mixed with water. Soak (merely don't fill up) the hole with h2o from a spray bottle; otherwise wet will be sucked out of the mix by the surrounding physical. And be certain you lot're fix to become before you mix the cement—it dries in three to five minutes.

Hex vs. Flathead Screws

Hex-head screws are less probable to strip out, so utilise them when the screw head can sit proud of the surface, as information technology tin can on sill plates and plumbing straps. Flathead screws are the way to go when the screw caput needs to be flush, such as with furring strips that will be clad with drywall or plywood.

Drill/Scrap Philharmonic Speeds Upwards the Procedure

Installing physical screws is even faster with a drill fleck/driver combination set like this i. The drill fleck is covered by the removable sleeve that contains the driver. That way you don't need to have two drills on manus, or to go along switching between drill bit and driver.

Drill 1/4 in. Deeper than the Length of the Screw

Ready the depth gauge on your drill and so the pigsty is 1/4 in. deeper than the length of the spiral, keeping in mind the thickness of the cloth you're working with. If your drill doesn't have a depth gauge, wrap a footling tape around the flake so you lot'll know when to stop. Always drill the proper bore hole. The container the screws come in volition point which size bit to apply. A fleck is included in some larger containers.

Spike Bottom Plates with a Powder-Actuated Tool

Many pro framers say the fastest mode to attach lesser plates to a slab is with a powder-actuated tool (PAT). Virtually residential-grade PATs are powered by .22 quotient blank cartridges, which drive in nail-like fasteners. Identify the fasteners near 5 ft. apart and within half-dozen in. of the end of a wall. Too, add a piffling construction agglutinative for more holding ability.

The PATs that require a hammer accident to burn down the load and those that have a trigger are both available at abode centers. Buy ii-1/2-in. fasteners and so they will penetrate the concrete nearly one in. to 1-1/4 in. Wearable prophylactic spectacles equally well as hearing protection—these tools are loud.
