You generally use a roller or a sprayer to apply sealer.
The choice between a roller and a sprayer often depends on factors such as the type of sealer (solvent-based or water-based), the surface area, and the desired finish. Always consult the sealer manufacturer's instructions for the best application method and specific guidelines.
Here's a breakdown:
-
Rollers: Rollers are a good option for applying sealer to smaller areas or when a more controlled application is needed. They are also often preferred for water-based sealers.
-
Sprayers: Sprayers are more efficient for larger areas and can provide a more even coat of sealer. They are commonly used for both solvent-based and water-based sealers, but proper safety precautions (like wearing a respirator) are crucial, especially with solvent-based products.
Always refer to the specific application guidelines provided by the sealer manufacturer for the best results. These guidelines will often recommend the most appropriate application method and any necessary safety precautions.
