Resurfacing Your Concrete Patios

Outdoor FX
If covered with an attractive surface material a patio can become one of the most useful exterior areas in your home. In most cases patios are usually covered with concrete which in most instances appear dull, dreary, ugly cracks and sometimes stained with grease and oil over time. If this is the case, then it is time you considered resurfacing your concrete patio. If it has cracks, you may have to employ professionals to rip it off and then relay it. However, if it is the general dullness or wearing out, then a resurface will do. 
Resurfacing concrete is just a simple way of improving the appearance of your patio when the exact structure of the concrete is indeed sound. Although you can hire someone to handle your resurfacing project, you may also consider doing it yourself.
Start by cleaning the entire patio or the area you wish to resurface. You can use a firm bristled brush to remove any dirt and loose concrete while ensuring to remove any visible mold. After cleaning the resurfacing area, dig a trench surrounding the concrete measuring around 4"x4". The trench is dug to allow you to place some basic formwork around the resurfacing area. This will make it easier for you to insert a thick layer of the new concrete. You may want to seek help with the preparation of formwork to ensure that it is level. Alternatively, find some useful information on how to prepare formwork.
At times, the new layer might have difficulties bonding with the old one. It is for this reason that a bonding adhesive for concrete should be applied. After preparing the concrete mix according to the instructions of the manufacturer, apply it to the resurfacing area using a shovel. Using a board that rests on top of the two opposite pieces of formwork, smooth the top of the poured concrete. Try to spot low areas and fill with more concrete and then embark on smoothing. After the concrete mix has filled the formwork, use a float to smooth the surface. Work fast to complete the floating task as fast as possible. After you are done floating you just have to cut the control joints using your trowel and your resurfacing task is complete. Finally clean all your tools to prevent the concrete from hardening on them.
