The Sealcoaters' Guide on How To Mix And Transfer Pavement Sealer
Sealcoating is not rocket science, but it's important to know how to mix and transfer pavement sealer correctly if you want to start out strong. This quick yet comprehensive guide from Action Seal will teach you how.
Things You'll Need to Mix Sealer in Drums
Here are the things you'll need to mix driveway sealer in a 55-gallon drum:
- A sealcoating drum mixer
- An 18V or 21V cordless drill
- An ordinary garden hose (make sure that it has a shut-off valve for hassle-free operation)
- A pair of work gloves to keep your hands clean
- A long stick or broom handle which you're going to use to check whether the sealer is properly mixed or not
How to Mix Asphalt Sealer
- Remove the lid of the sealer drum to check the liquid's consistency. The first thing you'll notice is water sitting on top of the thick black sludge. Water sitting on top means that what you have is an unmixed sealer. Once water and sealer are mixed you'll notice that the liquid now has the consistency of gravy or soup.
- But it's sometimes hard to tell if the sealer is mixed well or not, so we recommend that you perform a dipstick test. To do a dipstick test, all you need is a clean and long broom handle.
- Dip it straight down to the bottom of the drum and pull it up after a second or two (do not stir!) An unmixed sealer will have water coating the upper half of the stick, while black sludge will coat the lower half of the broom handle. Wash the broom handle clean and set it aside.
- Now, attach the drum/barrel mixer to your cordless drill and dip it down to the bottom of the drum. Turn the drill on and mix the liquids with an up and down motion.
- Make sure to scrape the bottom of the drum and mix it thoroughly from side to side afterward. Incorporating the contents of the whole 55-gallon drum will take about 5 minutes or so.
- After 5 minutes, get your clean broom handle and dip it straight to the bottom of the drum to check the mixture. A thoroughly mixed sealer should have the solid black sludge coating the stick from top to bottom. Check the broom handle and see if any lumps are covering it. If there are, mix it again.
Transferring Driveway Sealer into the Sealcoating Equipment
The sealer should be mixed by now, so it's finally time to transfer it into the sealcoat sprayer. Here are the guidelines on how to do it properly.
- Check the engine's oil level. Pull out the engine's dipstick and check if it has enough oil. Refill if it doesn't have enough oil.
- Check if there is plenty of gas in the machine's fuel tank. We recommend that you use only unleaded gas for this. Refrain from using old gas or any other types of fuel as this could result in some problems for your engine later on.
- Check the engine drain plugs to ensure that the sealer won't leak during operation.
Loading the Sealer into the Machine
- Open the machine's 2" transfer port.
- Check the lower ball valve's position to make sure that it is closed. To make sure that it is in the right position, adjust the handle until it is positioned non-parallel to the ball valve.
- Next, turn the top valve into the open position to circulate the sealer in the tank.
Attaching the Transfer Hose and Priming the System
- Detach the plug from the sealcoating equipment's transfer port and remove its pins. Unfasten the camlock and remove the plug.
- Attach the male end of the hose to the pump's 2" transfer port.
- Fasten the camlock, making sure that they are tight to prevent leaks.
- Get rid of any air in the system by priming the pump and hose. Start by positioning the end of your transfer hose above the level of the pump.
- Hold the female end of the transfer hose a little above the pump. Fill it with water, and stop when the transfer hose is full. Attach the female end of the hose into the drum attachment.
- Turn on the engine to initiate the transfer process from the 55-gallon drum to the sealcoat system. Apply the sealer to the driveway or parking lot once the transfer is complete.
Clean any drips as soon as you finish applying sealer to the asphalt. To ensure that it won't dry out, make sure that the transfer hose is sealed up and positioned neatly at the back of the truck.
Don't throw away any sealer that's left in the drum; reuse it the next time you're sealing a driveway or parking lot. Put the lid back on, and make sure to keep your drum kit clean by washing it with water. Making sure that the drum kit is clean will make it easier to use next time.
