Oil Spot Primers are a crucial product to use on asphalt driveways and parking lots where oil stains are present. Oil stains are usually caused by older, leaky vehicles that drop oil on the asphalt surface causing a black, slick stain that makes sealing asphalt almost impossible. In order to seal over these areas, your best bet is to use a primer like our BIG A Oil Spot Primer so the asphalt sealer has something to adhere to.  Otherwise, you'll find that the sealer doesn't stick and eventually comes off prematurely.

Other chemicals that an oil spot primer can help seal against include gasoline, grease, anti-freeze, transmission fluid or other similar types of oils and chemicals.

Our BIG A Oil Spot Primer is designed to be sealed over with a variety of asphalt sealers such as coal tar or asphalt emulsion based sealers but it's not recommended for Gilsonite Sealers.  In addition, you can easily and liberally apply this product with a spray machine, roller or oil spot brush, giving you a lot of flexibility with priming the oil spots.

A few things to note about this oil spot primer is that you don't want to use it if the asphalt is badly soaked with oils or gasoline (see the screw driver test below) and you want to make sure that the product doesn't freeze.

Screw Driver Test

If you aren't sure if you need to use an oil spot sealer, we recommend doing the "screw driver" test.

Over time, the oils and fuels will eat away and soften the asphalt to the point where a primer won't do much good.  This is where the screw driver test comes in.  Take a screw driver and push down around various areas of the oil spot area to see if it will sink down into the asphalt with ease.  You don't need to use a lot of pressure and if it does sink into the asphalt, you need to replace the area of asphalt that is stained.

Oil Spot Primers don't protect against damaged asphalt, so if the asphalt is so far gone that you can literally push a screw driver through it, it might be time to call out the professionals if you're mainting your own asphalt.

On the flip side, if the screw driver only sinks down 1/8" to 1/4" in a small area of the stain, then you can probably get away with putting a primer over it and seal the asphalt like you wanted.

Instructions Overview

Clean the stained area using a mild detergent (dish washing soap) and water. It works best if you use a hard bristle brush to clean and agitate the stained area.

Allow the cleaned area to dry before applying the oil spot primer.

Apply the BIG A Oil Spot Primer over the stained area and spread it out evenly about 1 foot away from the edges of the stain.  Usually, a brush or roller works best for spreading it out.

Allow the Oil Spot Primer to dry to the touch before sealcoating.
