Mixing Sand with A-Tech 1300

Mixing dry silica sand with A-Tech 1300 gives the material more body and extends the working time. Mixing sand is an excellent way to repair concrete spalls in driveways, garages and warehouse. It also gives UV resistance and helps A-Tech 1300 maintain its color. The repair will have a more natural concrete look after the repair is made. The strength of A-Tech 1300 is not compromised by adding sand.
