Step 3: Use a Broom to Finish the Surface Texture of the Concrete

Even by following my outstanding instructions it is doubtful that your surface will look a pro did it. As I said in the beginning, using a trowel isn’t all that easy. However, most of us are good with a broom. If your mother brought you up right, you’ve had lots of practice. Once you are finished with the trowel, simply take a soft broom and gently drag it across the surface. Always pull the broom (never push) and always go in the same direction. Just one pass should do the trick. I personally prefer a broom finish because it makes the surface slightly rougher. This is very helpful for those occasions when your sidewalk is wet. A hard troweled surface is very slick. Unless your brother-in-law is a really good lawyer, you don’t want someone take a tumble on your property. Concrete Repair is never fun.  Besides this way everyone will think you really knew what you doing and you won’t have to tell them about the broom trick.
<p>Thank you for this instructable. I learned not to play with it too much as this what my problem was last time. I am going to have a go at this project again.</p>
At times, I like the &quot;exposed aggregate look&quot;. But how and when to do this is &quot; touchy&quot; no?
Thank you for your series in making concrete projects. Every now and then someone wants to make a casting project with a concrete and a mold. Sometimes the &quot;top&quot; of the final project will be the shape of the mold (flipped over after curing) and sometimes the top will be the top surface of the dried concrete. Do you have recommendations for making smooth surfaces when casting flat or curved concrete? The projects I'm thinking of would be smooth enough to apply wax for a perfect shine.
As you well know concrete mixes are usually very porous once they set and that is mainly due to the gravel aggregate in the mix. The top of the mold area can easily be floated or troweled to a somewhat smooth surface but the bottom of the mold is much harder to control. The aggregate will fall to the bottom of the mold. My suggestion would be to allow for the top of the molded concrete to be the top of the project piece as it is the only side you can consistently control the surface of. If it is necessary for the bottom to be used as the top of the project, you may want to look into using an additional resurfacing material which dosen't contain the large aggregate such as the Sakrete Top N Bond Concrete Patcher. The&nbsp;patcher can be used once the concrete piece is set enough so that it is undisturbed when applying the Top N Bond.&nbsp;Hope this helps..<em>The Sakrete Team</em>
