Bests & Worsts Reviews from Amazon

Have a patio going in made of Buffalo Stone so I took the trouble to buy and test some sealers with the hope I could find a way to prevent staining from dropped food and drink. Bought: 511 Porous Plus, StoneTech Bulletproof Sealer, StoneTech Heavy Duty Sealer, Akemi Nano-Effect Stain Repellant, Akemi Super Stain Repellent and AquaMix Penetrating Sealer. Soaked samples of stone in each and let cure for a day. Put a drop each of red wine, balsamic vinegar and olive oil. Let it sit 5min and washed. Results: 511 Porous Plus and Akemi Nano-Effect had no staining Akemi Super Stain Repellent and Aquamix penetrating Sealer both had slight staining StoneTeck Bulletproof and Stonetech Sealer had significant staining. A few days later did it again on the same stones to see if double coating made a difference: NOPE But since longer stain time could stain in even the best, I did another test: double coat 511 Porous Plus separated by 15min followed by a coat of 511 Mira Matte while it was still uncured (VERY important apparantly). Success! And now it resists ground-in dirt too.
