Can SEMCO Natural Shield be used on painted surfaces?
The SEMCO Natural Shield needs pores to penetrate into the surface in order to be effective.
Is it slippery?
No, since the SEMCO Natural Shield is a penetrating sealer, your sealed surface will not change in look and feel.
Can SEMCO Natural Shield be used on cinder block?
Yes, absolutely! The SEMCO Natural Shield is technically a concrete and masonry sealer that can be used on vertical surfaces. It will make the wall repel water and should help with the efflorescence issue. If there are any cracks, you need to fill them before applying the sealer as the sealer does not span cracks and will not stop water from entering a crack.
