National Terrazzo and Mosaic Association (NTMA)
non-profit trade association
The National Terrazzo and Mosaic Association, Inc. is a full service Non-Profit Trade Association headquartered in Fredericksburg, Texas. The Association establishes national standards for all Terrazzo floor and wall systems and provides complete specifications, color plates and general information to architects and designers at no cost.
Membership in the Association is limited to Terrazzo Contractors who meet rigid proficiency standards and participate in continuing educational seminars conducted annually by the Association. Associate membership is available to material suppliers whose products comply with the standards stipulated by the Association.
Terrazzo is a custom flooring crafted essentially from natural products and subject to slight shade variations. Cement, both white and gray, may not be uniform in color. Since this color palette is intended for national distribution, substitutions of generally comparable aggregate (mainly marble) may be necessary or advisable in some cases. Care should be taken to assure that the aggregate supplier is a member in good standing of the NTMA and will provide all materials in accordance with NTMA standards.
The finished terrazzo should not be expected to precisely duplicate an individual color plate. Only the samples submitted by the terrazzo installer, when approved, may be considered to be a reasonably accurate representation of the finished floor, and may best serve as the basis for acceptance.
The NTMA Color Palette is intended as a guide for PRELIMINARY COLOR SELECTION ONLY. Terrazzo Contractor produced samples will not match exactly or have the same high finish.
