We provide pre-formulated oxide batches to produce concrete mortar that closely matches the color of the tile purchased on each order. Mortar is used to set the trim tiles or create a mortar eave closure. The pre-formulated oxide batches adequately color 100 Lbs. of Portland cement in the sand/cement mortar used to set trim tile or as eave closure. Be sure to use white cement for matching any of our Category 3 products.
