Frequently Asked Questions
Product Questions
What surfaces can I use Dallo USA products on?
Our products are designed for natural stone surfaces including granite, marble and quartzite. They are ideal for kitchen countertops, bathroom vanities, and other sealed stone surfaces.
Is your cleaner safe for daily use?
Yes. Our Daily Stone Cleaner is formulated for regular use and is safe on sealed stone surfaces. It cleans without damaging the finish or leaving residue.
Does the sealer change the color of the stone?
No. Our penetrating sealer is designed to provide invisible protection while maintaining the natural look of your stone.
How long does the sealer last?
Depending on usage and stone type, protection typically lasts up to 6 to 12 months. High-use areas may require more frequent application.
Application Questions
How do I apply the sealer?
Clean and dry the surface completely. Apply an even coat using a clean cloth or applicator. Allow it to penetrate, then wipe off any excess before it dries. For more porous surfaces, apply a second coat after 1 to 2 hours. (Recommended for Granite, Marble and Quartzite)
How long should I wait before using the surface after sealing?
We recommend waiting at least 24 hours before heavy use to allow full curing and maximum protection.
Do I need to reapply the sealer?
Yes. Like all penetrating sealers, reapplication is recommended periodically based on wear and usage.
Can I apply the sealer myself?
Yes. Our products are designed for both professionals and homeowners, with simple application steps.
