FAQ
- How often should I seal my garage floor?
Most sealants last 2-5 years, depending on use and wear. Check your floor yearly for new stains or dullness. If you notice these signs, it’s time to reseal.
- Can I apply sealant to a painted garage floor?
No, it’s not recommended. Sealant won’t stick well to paint and may damage it. You’ll need to remove the paint first, then clean the concrete before applying sealant.
- Do I need to prepare my garage floor before sealing?
Yes, preparation is crucial. Clean the floor thoroughly, removing all dirt, oil, and grease. Fix any cracks or damage, and follow product instructions for etching if required.
- Will sealing my garage floor make it slippery?
Some sealants, especially epoxy types, can make floors slippery when wet. Look for products with anti-slip additives or textured finishes to prevent this issue. You can also buy additives separately to mix into your sealant.
- How long before I can park on a newly sealed garage floor?
This varies by product, but generally, wait at least 72 hours before parking a car. For walking, wait 24 hours, and for heavy items, up to a week. Always check the product instructions for specific curing times.
