When to Seal New Concrete | Concrete Sealer Reviews ...
If you wait too long to apply sealer, the concrete will have to be cleaned and degreased. Another issue is that if you decide to use a clear sealer, it will show any stains that may have occurred. Basically, you should wait at least a month but not much longer, unless you are using a cure and seal, then you can seal new concrete as soon as the bead water is gone. If you have a question on this ......

How to Resurface an Aggregate Driveway | Hunker
The term aggregate refers to the crushed rocks added to cement to increase the strength and durability of concrete. On an exposed aggregate driveway, colorful stones are laid on top of wet concrete to add a decorative, unique touch. Over time, pieces of aggregate can dislodge if the concrete becomes brittle or water damaged, leaving unsightly ruts behind. Resurfacing an aggregate driveway is ......
Tips on exposed aggregate finishes| Concrete Construction ...
· Assuming the concrete has good aggregate to begin with, enduring freezing and thawing is the primary durability issue. That applies to all kinds of exterior pavements, not just those with exposed aggregate. You should work with the contractor to be sure the mix design has adequate air entrainment in it for the area in which you are working. Advertisement. Keywords: Subject: Aggregates Exposed ......

How Do You Attach Something to Concrete Without Drilling?
· For example, an ultralightweight concrete contains aggregates such as perlite or vermiculite. It is mainly used for insulation and is soft enough to saw and drive nails into it. Aggregates consisting of crushed limestone or bricks, expanded slate, or shale produce lightweight concrete. Both concrete products are less dense than those using hard aggregates, which makes it easier to apply ....
How to Properly Mix Concrete (DIY) | Family Handyman
Sixty or 80lb. bags of concrete mix are readily available at home centers, lumberyards and hardware stores. Don't confuse concrete mix with sand mix or mortar mix. They don't contain the aggregate (stones or gravel) that's necessary to make a pour thicker than about 3/4 in. You're likely to find more than one kind of concrete mix on the shelf, including "fast setting," "high early ......

4 Tips for Painting Aggregate Concrete |
· This transfers readily onto the aggregate concrete. Apply 3 to 4 thin coats of paint in the same manner as you applied primer. However, you may prefer to apply additional coats to get a deeper color and a more resilient surface. The appliion of several thin coats is better than one thick coat. Thin coats adhere to the concrete better and dry faster. Thick coats do not dry well and leave you ......
Surface Retarders for Exposed Aggregate| Concrete ...
· When applied to formwork they provide an abrasionresistant surface so that concrete, while being placed, doesn't remove retarder from the forms. Sprouts adds that for precast appliions where castings are put through steam cure rooms, heatresistant products that can withstand temperatures as high as 160° F are available. To facilitate the transfer of the retarder film to the ....
Exposed Aggregate Concrete
Exposed aggregate concrete is a finish achieved by laying a concrete with the chosen type of aggregate (either naturally rounded or crushed) and applying a "surface retarder" to the concrete once placement has been finished which prevents the top 3mm or so from setting. After a period of time (perhaps hours in summer, or overnight in winter) once the concrete has stiffened sufficiently the ......
