Our LLC does acid stain concrete floors. I am looking for a product that can fill fine fractures and larger fractures in concrete slabs with a fast drying time and little shrinkage.
At the present time, I use rock-ite which is anchoring cement or a divit patch to fix the cracks or holes. My problem is when coloring out the fixed fractures my acrylic paint and acrylic sealer do not bond or achieve a darker enough color on top of these materials. I have even added a dark acrylic paint in the white rock-ite and the color of it remains white. Only with a great effort and several topical application can I color it but it still does not darken up in color much.
I have been doing this work for over 10 years. Amazingly, some of the floors that I have had to fix have had mastic all over the floors. My colors adhere perfectly to the mastic, and the colors do not lighten up.
Do you know of a product that I can use. This would greatly improve the quality of my work and make my life a little easier.
