Product Description

Epoxytec B1 Primecoat™ is designed as a high performance sealer and coating formulated for concrete. Epoxytec B1 Primecoat ™ is supplied in a convenient one-to-one mix ratio. B1 Primecoat™ is capable of penetrating and filling the porous structure of concrete in order to provide an effective subsurface barrier to prevent moisture migration, out-gassing, and chemical penetration. Epoxytec B1 Primecoat™ exhibits highly penetrating properties which provide porous filling and strengthening of the top concrete layer to form a sufficiently strong base for subsequent top coats.

Product Applications

  • Concrete priming and sealing as a base coat
  • Industrial
  • Outgassing prevention barrier

B1 Primecoat meets these Requirements:

Typical Uses

B1 Primecoat™ is surface-tolerant for enhanced performance properties for industrial priming and sealing of concrete and other masonry surfaces.  Often utilized to prevent outgassing of concrete prior to coating.

Surface Prep

Coat only clean, dry surfaces. Remove all grease, oil, dirt or other foreign matter by solvent or detergent washing. Concrete: (1) Brush-Blast Cleaning (SSPC-SP7) can be used to prepare the concrete by removing all foreign matter and provide profile for bonding. Remove all dust from surface before starting the application of the coating. Epoxytec B1 Primecoat™ is recommended to prime and seal concrete. (2) Water Blasting: Water Blasting is acceptable ain order to meet the standards described in NACE No. 6/SSPC-SP 13, “Surface Preparation of Concrete.” Item# PR1 Revised: 4/5/2010 Previously Painted Surfaces: Remove all rust, rust scale, other corrosion products, loose or heavy chalk and loose or scaling paint by: Hand or Power Tool Cleaning” (SSPC-SP-2 or 3). Brush blast any glossy areas until dull. Spot prime bare areas as recommended and apply one or more coats of Epoxytec B1 Primecoat™ as specified. Check compatibility by applying coating to a representative area and allow to cure and age. Then make cross-hatched cuts through the coating and check adhesion by firmly applying masking tape to cross-hatched area and removing with a fast pull. If the coating remains intact and there is no wrinkling, lifting, blistering or any other sign of incompatibility present, coating work may then proceed. Mixing: Material is supplied in 2 containers as a unit. Always mix a complete unit as supplied (3B to 1A by volume). Thoroughly mix B Component before adding A Component. Combine entire contents of Part A and Part B and mix thoroughly with a Jiffy Mixer or equal for 2-3 minutes. Thinning: Supplied at spray viscosity, requires no thinning.

Application Method

Epoxytec B1 Primecoat™ can be applied by brush, roller, or spray. Induction Time: None required. To obtain maximum edge retention and film build, conventional or airless spray is recommended. Thoroughly flush equipment with solvent. Application by other methods, brush or roll, may require more than one coat.

Roller: short nap roller cover. Dynel recommended. epoxytec.com/products/B1_Primecoat TM B1 Primecoat
