Asphalt-Based Emulsions Vs
Acrylic Resurfacers
• Each gallon of Acrylic Resurfacer can suspend only 15 to 16 lbs of sand. The major
purpose of a resurfacer is to fill up holes in pavements and to enhance fine coating on
existing smooth surfaces. Altogether, resurfacing impacts on the overall consistency of
the playing surface and prolongs the lifespan of the colored surfaces.
• Every gallon of Asphalt Emulsions can suspend only 5 to 6 lbs of sand. Simply put, it
takes three gallons of AE to provide the same filling capacity one gallon of AR gives.
• AE comprises molecules that soak up moist which can weaken some sections of the
coated layers. It can also cause bulging. During cold weather conditions, this can cause
de-lamination of surfaces and early failure. If AE is applied over a polished acrylic
surface, the asphalt layers have increased the propensity to absorb lots of moisture
that moves through coatings at a slower pace.
• It is advised to roll over asphalt emulsions after application to obtain a fine coating.
• With Acrylic Resurfacers, rolling over is not necessary.
• Both Resurfacers need a minimum asphalt curing period of two weeks (under premium
restoration conditions), before application. While this is so, 30 days is advised to
ensure optimum effect, especially in climatic conditions when curing isn’t ideal.
• AE needs 24 hours to cure prior to the application of acrylic colors coating.
• AR can be applied with acrylic colors even when dry.
• Asphalt Emulsions are susceptible to temperature changes as they become mushy
under intense heat. During hot days, these can create bulges. AE surfaces can also
crack during cold weather conditions, whereas AR remains intact regardless of weather
conditions.
