Oil-based sealers are formulated for various types of interior and exterior concrete surfaces. The solvent of the sealer in which the resin is dissolved is oil-based and offers excellent adhesion. Nowadays, you can get both oil-based acrylic sealers and polyurethane sealers. Using an oil-based concrete sealer can help protect and extend the life of all concrete surfaces.
These concrete sealers are usually clear and will not get yellow or discolored over time. It is also damage resistant from water, chemicals, salt, UV rays, heavy traffic, and cleaning agents. However, the downsides to oil-based sealers are that they have a strong smell and take a long time to dry.
The uses of oil-based sealers include:
Oil-based concrete sealers accentuate all the inconsistencies on the concrete surface. So, before you apply the sealer, ensure that you sand the surface and remove all the dust and debris. Avoid shaking the sealer can because this can cause bubbles, which can leave bumps on the surface. If the sealer’s consistency is too thick, then use mineral spirits to thin the sealer.
You can apply this concrete sealer in a thin coat using a paintbrush. Wait for 24 hours or until the sealer is completely dry and then remove any dust or debris. Apply the second coat of sealer and allow it to dry completely. Just two coats of the oil-based sealer are sufficient. Wait for a few days and then polish the concrete surface using a polishing compound.
