Buying Guide
Choosing the right water-based concrete sealer depends on a few factors. Here’s what to consider:
- Type of Concrete: Is it standard concrete, stamped concrete, or pavers? Different sealers are formulated for different types of surfaces.
- Climate: If you live in an area with freezing temperatures or heavy rain, you’ll need a sealer that can withstand those conditions. Salt resistance is crucial if you use salt on your driveway.
- Desired Appearance: Do you want a glossy, wet-look finish, or do you prefer the natural look of the concrete? Acrylic sealers provide a glossy finish, while penetrating sealers leave the concrete looking natural.
- Traffic Level: High-traffic areas require more durable sealers that can withstand wear and tear. Consider the AR350 for a nice look but keep in mind its durability compared to penetrating sealers.
- Budget: Sealers range in price, so set a budget before you start shopping. Remember that cheaper sealers may require more frequent reapplication.
- Application: Some sealers are easier to apply than others. Read the instructions carefully and make sure you have the necessary tools. Always prep the surface well before applying any sealer.
FAQs
Q: How often should I seal my concrete?
A: It depends on the type of sealer and the amount of traffic the surface receives. Acrylic sealers may need to be reapplied every 1-3 years, while penetrating sealers can last much longer.
Q: Do I need to clean my concrete before sealing it?
A: Yes! Cleaning is essential for proper adhesion. Use a concrete cleaner and degreaser to remove any dirt, oil, or stains. Consider using a concrete etcher like Eagle Armor Etch for even better results.
Q: Can I apply a water-based sealer over an existing solvent-based sealer?
A: No, it’s generally not recommended. Water-based sealers may not adhere properly to solvent-based sealers. It’s best to remove the old sealer first, if possible.
Q: What’s the difference between a penetrating sealer and a topical sealer?
A: Penetrating sealers soak into the concrete and provide protection from within, while topical sealers form a protective layer on the surface. Penetrating sealers generally last longer and don’t change the appearance of the concrete as much.
Q: How do I know if my concrete needs to be sealed?
A: Pour some water on the concrete. If the water beads up, it’s likely sealed. If the water soaks in, it’s time to seal it.
Conclusion
Choosing the right water-based concrete sealer can protect your concrete surfaces and keep them looking great for years to come. Consider factors like climate, traffic, and desired appearance when making your decision. Whether you opt for the long-lasting protection of Foundation Armor SX5000, the wet look finish of Armor AR350, or the budget-friendly Mighty Seal, you’ll be giving your concrete the protection it needs. Don’t forget to properly prepare the surface with a product like Eagle Armor Etch for the best possible results. Good luck with your project!
