Dense Stone Sealer FAQ
Why use a dense stone sealer on granite?
Granite and marble have tight pores, so standard sealers can stay on the surface. The super saturator in Dense Stone Sealer carries the sealer deeper.
Is Dense Stone Sealer the same as Stain-Proof Plus?
Yes, it was formerly sold as Stain-Proof Plus.
Is it food safe?
Yes. Stain-Proof states that once cured, Dense Stone Sealer is food contact safe.
Does it change the look of the stone?
No. It is invisible and retains the natural colour and finish; some surfaces may lighten or darken slightly, so test a small area first.
How often should granite be sealed?
Stain-Proof describes the repellency as permanent; test by placing a few water drops on the surface. If they soak in and darken the stone, it is time to clean and reseal.
