Yes, but only after cement has completely set and dried. It must then be sealed with concrete sealer or painted with a high grade exterior paint.
How much water do I mix in with Rockite and Kwixset?
3.5 oz of water per pound of cement for a thick mix. 4 oz of water per pound of product for a thin, pourable mix. Be careful not to use too much water! Use just enough water to achieve a thick pancake batter -like consistency.
I mixed my Rockite and started to use it. Now it is starting to set. Can I mix more water with it to increase the working time?
No! Once you mix the Rockite it must be used immediately. When it starts to set, it is too late to mix in more water; you must mix another batch. It is a better idea to make small batches as you go.
Do I have to paint Kwixset after I use it outdoors?
No, Kwixset is weatherproof and does not need to be sealed or painted outdoors.
