Henry Ford did just fine with a car available in any color, so long as it was black. And the common-sense recognition that beauty is sometimes in performance more than in appearance may account for the slow movement of color into concrete manufacture. But now that color’s here, you may well consider concrete as the best material for projects once done in less reliable stone or brick. Sealers are essential to making both indoor and outdoor projects last as long as possible. The best effects, however, begin with additives pre-measured for blending into casting materials. BDC’s stock of Surecrete color additives includes mixers for exterior and interior jobs, along with additives that intensify concrete hardness.
