Key takeaways
- Sealers protect concrete from water, salt and stains
- Penetrating sealers keep the natural look
- Film-forming sealers add a sheen and may be slick when wet
- Resealing every few years keeps protection fresh
What a sealer does
Concrete is porous. A sealer fills the pores so water, salt and oil cannot soak in, which slows cracking from freeze-thaw and makes stains easier to remove.
Some sealers enhance color and add a wet look. Others are invisible.
Choosing a type
Penetrating sealers soak into the concrete and leave the surface natural. Acrylic and polyurethane sealers form a film on top with more sheen and a deeper color.
Film-forming sealers can be slick when wet unless a grip additive is used.
When to seal
Seal when the concrete is clean, dry and not about to see rain. Many driveways are resealed every two to five years.
Heavily stained or cracked drives may need cleaning and repair first.
