What is a concrete tamper? Tampers (sometimes called Jitterbugs) push the coarse aggregate in the concrete below the concrete surface and consolidate the concrete.

What can I use instead of a tamper?
An ordinary sledgehammer is a better hand-operated tool for tamping. Handle vertical, lift and drop, repeat. Doing a good job with one is tedious but quite possible if you prefer not to rent a powered plate compactor. For something like compacting around a fencepost, an iron digging bar can be used to compact.

What is tamping concrete?
Tamping is one of the last steps in finishing a concrete surface. It is used to compact low slump concrete mix while it’s still wet, making it stronger and more durable.
How to smooth concrete?
1. Smooth the concrete with a float. Draw the float over the surface of the concrete just deep enough to reshape the outermost layer. Use wide, circular motions, or run it back and forth like a saw. This will leave the concrete with a seamless low-slip finish.
How to keep concrete from drying out?
Keep exterior concrete wet. Spray down driveways, sidewalks and other outdoor surfaces with a water hose. Aim to rewet the fresh concrete 2-3 times a day for the first three days. A little moisture will keep the concrete from drying too rapidly, which can cause it to become brittle.
Why is it important to fill in concrete forms?
It’s important that the forms get filled in completely so that the concrete is flush the corners. Failure to spread the concrete all the way to the edges of the forms could result in structural weakness or make the finished surface appear sloppy and incomplete.

Most types of concrete are considered to have reached full strength after 25-30 days. Avoid stepping on or otherwise interacting the concrete for the first week or so.

A piece of scrap 2x4 costs next to nothing, but requires more intensive labor and an up-close-and-personal approach to application. Tampers should only be used on “low slump” or harsh mix types of concrete, in which the coarse aggregate materials don’ t sink natural ly.
How to make a tamper stronger?
The screws and wire help fix the branch to the concrete and make the entire tamper stronger. Drill screws into the branch and wrap wire around each screw. The string is tight between two points, like a guitar string, and runs back and forth twice, and is twisted around itself.

What Is a Tamper Tool?
Tampers are manually operated or power compaction tools. They increase the density and levelness of soil, gravel, sand and other materials by applying force to the material’s surface. This force can be delivered by hand or via a gas-burning engine.
Types of Tamper Tools
Although all tampers share a common purpose, how they achieve it varies greatly from one type to the next.
How To Choose the Best Tamper
When choosing a tamper, begin by asking yourself what you will use it for. If you plan on compacting lots of material often, consider a gas-powered model. Only have a little tamping to do for a small project? Go with a long-handled manual tamper.
