Many of our asphalt paving customers ask the same questions about the installation process and about sealcoating their asphalt. So, we thought we’d compile a few of the frequently asked questions all in one place! If you have another question about asphalt or sealcoating, please feel free to contact us!
Should construction crews be allowed to pave in the rain?
Occasional light sprinkles should not be a reason your asphalt paving contractor shuts down operations; however, during a steady downpour for safety reasons (think lightening) and installation reasons. First, it is important to pave on a firm, stable, well-draining crushed aggregate base – rain or no rain. If the rain starts to erode the base, paving should stop. Additionally, rain water will cool the asphalt mix and can make it difficult to properly compact the surface. Puddles of water can also cause the separation of the asphalt binder from the aggregate.
After new asphalt is installed how long do you wait before sealcoating?
If you’ve just had your parking lot paved with new asphalt, and are concerned about protecting your investment, you’ll want to sealcoat the pavement. So, how long to you wait to do that? The general rule of thumb is to wait one year before sealing new asphalt. This allows the surface to rid itself of light oils, through oxidation. To make sure you’ve waiting the proper amount of time, spread some water on the surface. It the water spreads evenly without beading, and shows no “rainbows” from surface oils you are ready. This is also called “water break test”. The exact amount of time will vary slightly depending on geographical locations.
Should sealer be applied in one thick coat or two thin ones?
Much like paint, sealer applied in two coats dries and cures much better than one thick coat application. Remember sealers are water-based coatings, which cure through the evaporation of water. A thin coat will release water much faster than a thick coat. If applied in one thick coat, sealer will have a tendency to hold water and stay soft for a longer period of time.
Why would sealer dry to a gray color?
If the sealer does not cure to its normal charcoal black dried color, it is possibly due to the sealer curing under shaded areas or the surface contained too much moisture. In these cases, the problem may be temporary and after a few days in full sun it will cure to its normal color. Temporary graying can also be eliminated through the use of specialty additive that helps sealer dry faster and at a uniform rate. Another reason sealer may dry to a gray color is because of higher clay and filler content in the sealer itself. If after a few days it does not darken, consult the manufacturer or your installer.
