How To Choose The Right Size For Sealcoating

When it comes to sealcoating spray tips, knowing which size to use can make the difference between a professional, profitable job and a messy, time-consuming one. With tips being the most often replaced part on your spray system, knowing which spray tip sizes you should have on hand is critical.

Choosing spray tip sizes

Understanding GPM

GPM is short for Gallons Per Minute, and that tells you the amount of sealant that is being sprayed by the minute. You’d think, the larger the number the better it is, since you are getting the sealant down fast and finishing fast. As with everything, there’s a downside. The higher the GPM on your sealcoating spray tips, the more overspray you have. That means you have to protect the edges better, and you are losing more product on that protective barrier. Spray tip sizes that are 2 GPM give you a precise fan spray with far less waste. Now that you understand how GPM affects your results, the spray tip size chart makes a lot more sense.

What Sealcoating Work Do You Do?

When your work is residential, and you’re most often dealing with 4 to 6 car driveways, the 2 GPM sealcoating spray tips are your go-to. Why choose the slowest of the spray tips sizes? Because the area is small enough that the flow rate is more than good enough, and you have the precision fan spray you need to work around sidewalks, garages, pathways, and flower beds. That’s what we used in this video below. You can see you are done in less than 10 minutes, and the edges are clean. That’s why the 2 GPM is listed in the Spray Tip Size Chart for use on driveways.

Parking lots are different and with all that asphalt to seal, you can really save time by choosing from either the 3 GPM or the 4 GPM spray tip sizes. If you’re working on small to medium size lots, use the 3 GPM; for large parking lots, use the 4 GPM sealcoating spray tips. Basically, the bigger the area you will be sealing, the larger the tip should be, just like it shows in the Spray Tip Size Chart.

Remember: You can always do the edging first with a spray gun set up with the smaller tip first, then power through the rest with a larger size.

Spray Tip Size Details Best Use Of
2 GPM Small fan spray - precise control Driveways
3 GPM Medium fan spray - some control Small to medium size parking lots
4 GPM Large fan spray - better when overspray is not a concern Large parking lots

Now you know to choose like a pro. It’s the little things that make the difference to a professional and profitable business. Spray tip sizes are a regular expense in asphalt sealing, so using the right size for the right job will help you save on time, product, and money. Choosing sealcoating spray tips is simple; small for driveways, larger for small to medium parking lots, and the largest for big parking lots.

    Thanks for sharing this post! I have been thinking of spray sealing my driveway since it was just repaved. I don't want to have to deal with cracks for a long time, and it looks like this spray seal could help me do the trick. Now I know that I should get the smaller spray tip so that I have more control. Hopefully now I'll be sure to not leave a big mess when I'm done!

    Thanks for the information! The parking lot in front of my store needs to be repaired, so I need to know what spray tip size to choose once it's ready to be sealcoated. I have a large parking lot, so it's very important to have a fan spray that's large enough. It's a good thing that you have this chart to clearly explain what spray tip to use. I'll make sure that a 4 GPM tip is used, especially since overspraying sealant most certainly won't be a concern.

    You're right about how parking lots need different amounts of seal coating. That's why it's so important to have a good idea of the spray tip size that you need to apply the right amount of sealant to asphalt. I have a fairly small driveway, so I'll keep in mind to use 3GPM spray tip. Thanks for the useful advice!
