GENERAL: All surfaces must be clean and free of oil, grease, dirt, mildew, loose rust, mill scale, form release agents, curing compounds, deteriorated and poorly adhered coatings, efflorescence and any other surface contaminants. Use Richard's 248 Shield's All Oil & Grease Remover to remove contaminants, petroleum-based oils, grease, vegetable and animal fats. 

SURFACE REPAIRS: Repair/replace any damaged and/or delaminated surface areas with the proper recommended patching and/or building materials. Allow all patching materials to dry thoroughly before application of paint coatings. • 

PAINTED SURFACES: Remove loose, scaling, cracked or peeling paint from previously painted surfaces in accordance with The Society for Protective Coatings specifications. Sand rough paint edges smooth to adjacent surface area. Sand glossy surfaces. Spot prime bare surface areas with recommended primer material and allow to thoroughly dry before applying finish coatings. 

FERROUS METALS – IRON & STEEL: Remove all surface contaminants, oil and grease in accordance with SSPC-SP1. Remove loose rust and rust deposits in accordance with SSPC-SP 2 – Hand Tool Cleaning, or SSPCSP 3 – Power Tool Cleaning specifications. For optimal performance, clean the surface by abrasive blasting to achieve SSPC-SP 6/NACE 3 – Commercial Blast Cleaning standards. Prime all bare metal within 8 hours before flash rusting occurs. 

GALVANIZED STEEL & ALUMINUM: Exterior galvanized and aluminum surfaces that have weathered for at least 12 months should be cleaned by pressure washing prior to application. If coating new unweathered aluminum or galvanized steel, particularly chromate treated or passivated metal surfaces, apply a spot test and check adhesion. • 

NEW MASONRY & CONCRETE: All new masonry surfaces must be allowed to dry/cure a minimum of 30 days before coating. Remove curing compounds, concrete hardeners and poorly adhered coatings by chemical or mechanical methods. An acceptable prepared concrete surface should be free of contaminants, laitance, loosely adhering concrete, and dust, and should provide a sound, uniform substrate suitable for the application of protective coating systems. The surface area to be painted should be porous. Where acid etching is to be used for surface preparation, mix muriatic acid with water, 3 parts water to 1 part acid. Apply acid solution to the surface using a plastic garden sprinkler can. Allow the solution to effervesce or boil on the surface until it stops, (approximately 10 – 15 minutes). Do not allow floor to dry prior to rinsing. Add acid solution to keep wet, if necessary. Neutralize floor with an alkaline solution of 1 cup of baking soda (or 8 oz. of ammonia) mixed with one gallon of water. This mixture will neutralize any unspent acid. Rinse the surface thoroughly with clean water. Check pH of rinse water with pH range paper. Rinse water should have a pH of 6 - 9. If pH is outside of this range, rinse again and re-check pH. Properly etched concrete should have a texture feeling similar to medium (180) grit sandpaper.

This is a two-component material that requires equal amounts (by volume) of Part A and Part B. The mix ratio is 1:1. Mix each component separately before mixing Parts A and B together. Mix Part A and Part B together in a container large enough to allow mechanical mixing. Mix using a Jiffy Mixer at low speed for 3 to 5 minutes. Scrape the sides of the container occasionally while mixing to ensure uniformity. Avoid mixing too fast. Do not whip air into the product. NOTE: Only Mix What You Intend To Use. Neither Component Will Work Unless Mixed With The Other! 

INDUCTION: Allow mixed material to sit for 30 minutes prior to use. 

POT LIFE: Useable pot life at 77° F is 6 - 8 hours. (Higher temperatures will shorten pot life.)

Richard’s Python Polyamide Epoxy Coating may be easily applied with a quality brush, roller, or spray equipment as follows NOTE: This is a two-component material that requires both Part A and Part B. Do not mix partial kits 

Stir thoroughly in a spiral up and down motion before and during application to keep product completely mixed. Always paint to a natural break in the surface, such as a corner or edge. 

For best results, it is recommended to apply two (2) finish coats. 

Brush Applications: When applying by brush, use a quality natural bristle brush, and apply a smooth and generous coat on smaller surface areas, such as cutting-in larger surfaces and painting trim. 

Roller Application: When applying by roller cover, use a quality ¼ - ½ inch nap cover, depending on surface porosity. 

Spray Application: When applying by airless spray equipment, use a unit with a minimum of 2000 psi of pressure, with a 0.015 – 0.017 fluid spray tip. 

Rough or textured surfaces coated using spray equipment should be back-rolled to ensure a uniform film, even coverage and proper adhesion. 

Maintain a wet edge during application by brushing, rolling or spraying into previously applied coating area. 

Apply when surface and ambient temperatures are above 55° F and below 90° F. Do not apply when surface and air temperature is within 5° of the dew point. 

Avoid exterior paint application when weather conditions are threatening, and late in the day when there is a threat of moisture condensing on wet paint. 

CAUTION: Do not leave mixed material in spray equipment beyond the expected pot life. 

NOTE: All epoxies will chalk & discolor on exterior exposures. However, this is not detrimental to the anti-corrosive properties of this material. Where gloss and color retention is important overcoat with Richard’s 2400 Acrylic Urethane Gloss.
