Is it better to spray or roll paver sealer?

When it comes to sealing pavers, there are two primary approaches – spraying and rolling. Each approach offers its own set of advantages and disadvantages; which one you choose ultimately depends on factors such as type of sealer used, condition of pavers and personal preference. Here we explore both techniques so that you can make an informed decision.

Spraying Paver Sealer: Spraying paver sealer requires using either a pump sprayer or specialized sealer sprayer to apply an even coat over pavers, with some advantages of doing it this way:

  1. Quick and Efficient Application: Spraying sealer allows for fast and efficient coverage when covering large areas quickly and efficiently. You can cover an extensive surface area in a relatively short amount of time.
  2. Even Coverage: When applied correctly, spraying provides an even and consistent coat of sealer on pavers that helps enhance their aesthetic while protecting them against UV rays, water, and other external forces that damage them. This helps extend their longevity as well.
  3. Accessibility: Spraying makes it possible to reach areas that might otherwise be inaccessible with a roller, such as narrow gaps between pavers or intricate patterns, providing maximum protection. It ensures all pavers are adequately sealed against rainwater infiltration.
  4. Cost-Effective: Spraying can often be more cost-effective than rolling as it requires less labor and time investment, making it the go-to choice for large areas or commercial projects that need sealing.

Although spraying provides numerous advantages, there are some considerations when using this approach:

  1. Overspray: Spraying can result in overspray, potentially spraying sealer on surrounding surfaces such as windows or doors or nearby plants, leading to overspray issues. Therefore it is crucial that precautions are taken prior to beginning spraying to safeguard these areas before beginning this process.
  2. Wind Conditions: Wind can hinder the spraying process by dislodging sealers away from their intended targets, so selecting a calm day with minimal wind can ensure precise application of sealer sealants.

Rolling Paver Sealer: Rolling paver sealer can be achieved using either a paint roller or special sealer roller to apply sealant directly onto pavers. There are various advantages associated with this method:

  1. Controlled Application: Rolling provides more control over how much sealer is being applied. A thinner coat can easily be achieved, which may prove helpful when dealing with certain types of pavers or when creating a lighter finish is desired.
  2. Reduced Overspray: Rolling sealer offers reduced risk of overspray, making it ideal for areas with nearby surfaces needing protection.
  3. Improved Penetration: Rolling helps sealer penetrate pavers’ surfaces more thoroughly, guaranteeing maximum adhesion and protection – something which may be particularly advantageous in cases involving older or more porous pavers.
  4. Perfect for Small Areas: Rolling is an effective solution for sealing smaller areas or intricate patterns where spraying might prove challenging or ineffective.

However, rolling paver sealers do have their limitations:

  1. Time Consuming: Rolling is generally more time consuming when applied to large areas than spraying, as it requires additional labor and effort compared to spraying; making it less suitable for larger projects.
  2. Uneven Application: Getting an even coat of sealer applied using a roller can be more challenging. Doing it incorrectly could leave streaks or uneven coverage which will require careful and constant application to avoid streaking and streaks appearing over time.

Spraying and rolling are both viable methods for applying paver sealer, with the latter often providing greater control. When working with large areas or hard-to-reach spots, spraying may be more efficient; otherwise rolling may provide greater control. Either way, it’s essential to evaluate each method to select one that suits your project requirements best.
