    Nice wet look finish sealer without a sheen! Make sure to apply it in one thin even coat, do not apply too thick or too heavy, other than that it looks good

    Gave my stone patio a darkening effect without it being slippery or shiny. Just what I was looking for. Make sure to test out the Gem-Tek 5100 first since I initially applied it too thick and was left with an uneven wet look. Like the reviewer said above apply one even thin coat otherwise you might get an uneven appearance.

    Apply with a roller not a brush otherwise you will see the brush marks

    Product worked great. Easy to apply. Leaves a nice finish.
