Why should I go with A.J.'s Curb Design? How much does it cost? What are A.J.'s Curb Design products made with? For curbing and walkways, we exclusively use "Portland Cement" -proven to be durable and resistant to the elements. How do you make the different shapes, colors and surface patterns? For Custom Edging, A.J.'s Curb Design uses Custom Molding Equipment that extrudes the concrete into a variety of edged shapes. Colors are added to the concrete mixture before it is applied. 3 different colors can be added if done as an overlay. While the product is still soft, the surfaces can be "stamped" with a selection of creative patterns. For both curbing and walkways, a shiny appearance is achieved with a coating of High-Gloss Sealer. Back To Top How many different shapes, patterns and colors can I choose from? Currently we offer 5 molding shapes for curbing - 1 walkway mold, 16 individual stamp patterns, and 51 colors. Three different "overlay" colors are also available. What sort of preparations do I need to make before installation? Sprinkler heads and utility lines should be flagged before we begin with operations. Check to see if the immediate work-site is clear of obstacles such as vehicles and outdoor furnishings. Back To Top Do I need to be at home when you get started? If possible, we prefer our customers to be present at the work site. In the event this isn't feasible, bed lines should be lightly marked with colored chalk or spray paint. Our crew will need to be made aware of any property line factors or special concerns. Is the process very noisy? Our concrete extrusion equipment is about as loud as a gas powered lawn mower. Back To Top How long does it take for the concrete to dry? 24 hours is a standard period for curbing or before allowing foot traffic on walkways. Full curing takes approximately 28 days. During this time you will observe the concrete becoming lighter in color. What is the best way to maintain my Custom Curbing? Watering the ground around the edges for the first three days will assist the curing process and help prevent cracks from developing. Over time, calcium carbonate deposits (known as efflorescence) may form on the surface. This may cause discolorations in the concrete. Efflorescence can be removed using a solution of 1-part muriatic acid to 5-parts water. A Curing Sealer is strongly recommended; particularly for colored concrete. This is best applied prior to the curing stage and will prevent the initial buildup of carbonate deposits. Back To Top What else should I know about sealing products? Curing sealer will appear glossy at first but will result in a matte finish. To obtain a shiny appearance, a high gloss sealer, containing at least 25% solids can be applied after the 28-day curing process. For best results, we suggest resealing your custom curbing after six months, and then once each following year. At additional charge, we can provide this service for you or you can purchase a sealing formula at most hardware stores, and apply it yourself with a pump garden-sprayer device.
