Euclid Chemical Tammolastic

Tammolastic is a protective, decorative, flexible coating, formulated from high-performance elastomeric acrylic resins. It is designed to waterproof, bridge hairline cracks, and enhance the esthetic appearance of concrete, stucco, and masonry surfaces. TAMMOLASTIC provides long-term protection from severe weather over a wide range of temperatures, dirt, airborne pollutants, and is resistant to ultraviolet light degradation and carbon dioxide. TAMMOLASTIC has superior adhesive, cohesive, and color retention characteristics.

Note - Coverage rates are approximate and are for estimating purposes only. Surface temperature, porosity, and texture will determine actual material requirements. Apply samples to all surfaces to be coated, and obtain approval of the architect or owner for the color, finish, water repellency, and coverage before proceeding with work.

Directions For Use

Surface Preparation

Cure new concrete and masonry surfaces 28 days. Surface must be structurally sound, clean, dry, and free of dust, dirt, oil, peeling paint, curing and form release compounds, and other contaminants. Provide an absorptive surface on smooth precast, formed concrete, and other substrates by abrading the surface. Defective concrete and other surface defects should be routed to sound material and patched using compatible restoration products.


Priming

All surfaces to be coated with TAMMOLASTIC must be primed. For concrete surfaces, prime with TAMMS H/P Primer. For highly porous concrete block, prime with TAMMS MASONRY PRIMER.


Mixing

TAMMOLASTIC should be mechanically mixed using a low-speed 19mm drill with a mixing paddle. Mix thoroughly to a uniform, smooth consistency. Do not aerate the mix.


Application

  • TAMMS H/P PRIMER - Use airless spray equipment with 0.017 to 0.021 inch orifice size spray tips, or paint rollers to apply TAMMS H/P PRIMER. TAMMOLASTIC may be applied to the TAMMS H/P PRIMER as soon as it is dry to the touch.
  • TAMMS MASONRY PRIMER - Use heavy-duty spray equipment capable of spraying ceiling texture, plaster, or cement-based coatings, or use stiff brushes or 1-1/2” (38.1 mm) nap rollers designed for latex paints. Dampen brushes and rollers with clean water before use. When sprayed, back rolling is required to ensure appropriate uniform contact with the surface. Avoid applying to excess, which can cause the product to run down the wall or puddle. TAMMOLASTIC may be applied to the TAMMS MASONRY PRIMER 12 to 24 hours following primer application
  • TAMMOLASTIC - Use spray equipment with 0.025 to 0.031 inch orifice size spray tips, paint rollers, or brushes to apply TAMMOLASTIC.
  • If spraying - Use the “cross coat” technique of a horizontal pass, followed by a vertical pass. Avoid applying excess, causing the product to run down the wall or puddle. Back rolling is recommended during application of the first coat. A second coat can be applied after the first coat is dry, typically 12 to 24 hours.
  • If rolling - Use rollers with 1” to 1-1/2” nap. Dampen the brushes or rollers with clean water and shake our excess water before use. When using rollers, uniform millage is best achieved by rolling the TAMMOLASTIC in one direction. Do not back roll. A second coat can be applied after the first coat is dry, typically 12 to 24 hours.
