There are so many types of concrete sealers on the market today, and this makes it very difficult for a homeowner to find and simply seal there concrete.
So let me explain tips and tricks to get your concrete sealed.

How to apply concrete sealers;
#1. Take a look at the weather forecast/radar. You'll want to seal with no rain in forecast.
#2. Rent or buy a good quality Chapin sprayer, purchase a adjustable nozzle tip for the sprayer. This will help the sealer dispurse evenly. This sprayer will allow faster application and even thin coat.
#1. Put on safety glasses or the appropriate safety wear.
#2 The concrete will need to be pressure washed off with water, all expansion joints and surface area. Washing in the evening is best.
#3. Allow concrete has to be dry for sealer adhesion, using a leaf blower will help dry the concrete. Applying sealer in the morning is best.
