EQUIPMENT:

The equipment suggested to apply and remove GRAFFITI - PRUF is as follows:

(A) Airless Sprayer providing a minimum of 1500 psi through a tip appropriate for the surface being sprayed.

(B) Hot Water Pressure Washer. The washer must be capable of sustaining a water temperature of 170 degrees F., at the tip, at a pressure of between 300 and 1000 psi. A water flow of at least 2.2 gallons per minute is recommended.

(C) Water Supply. Carry a tank of water if on site water is not available.

(D) Paint Brush. A poly-foam brush is generally preferred, and is also used to brush out build ups and drips.

(E) Paint Roller. A roller suitable for use with water base paints should be used. Rollers should only be used on smooth surfaces or to remove runs from rough textured surfaces.

PROCEDURES:

Recommended Method of Application:

SPRAY - All rough or textured surfaces.

BRUSH & ROLLER - Smooth surfaces.

(A) Inspect the surface to ensure that it is clean and dry and that any paint or surface coating is in good condition. If necessary clean the surface of all dirt, grime and oxidized paint and any other loose material. Do Not Apply GRAFFITI - PRUF over flaking paint.

NOTE: If the surface has graffiti on it, this must be removed before GRAFFITI - PRUF coating is applied. Ensure any new paint has adequate time to dry and cure before applying GRAFFITI - PRUF.

NOTE: If the surface paint is flaking or cracked, all loose material must be removed before applying GRAFFITI - PRUF. As a general recommendation, do not coat such a surface.

(B) Allow the surface to almost dry, if it has been cleaned, or if it is wet from other causes. The surface need not be completely dry, but should not have surface water, or water drops, on it.

NOTE: The GRAFFITI - PRUF coating will allow the surface to breath and release any water contained within it when applied correctly.

(C) To apply the GRAFFITI - PRUF by means of an airless sprayer, hold the spray tip about 8 - 12 inches from the surface and move it horizontally, maintaining the distance from the surface to the limit of arm movement. Roll the wrists at the beginning and end of each stroke so as to provide even entry and exit to the spray area. Operate the spray trigger at the mid-point of the entry roll and release it at the mid-point of the exit roll.

The spray gun should be held at right angles to the surface. Start at the upper level of arm extension and do a forward and backward horizontal stroke over the same area. Move to the bottom of the sprayed area and repeat. Continue to the bottom. Move sideways to the edge of the sprayed area and repeat. Continue until all the surface is covered.

(D) Check for runs and areas where too much spray has been applied. These areas will appear to be slightly milky looking. Use the paint brush & spread these areas smooth with the surroundings.

NOTE: MORE IS NOT BETTER ! A heavier application will cause yellowing.

(E) Check to ensure all vertical grooves, and all nooks and crannies in the surface are properly coated. A vertical spray stroke may be needed in these areas.

NOTE: The speed of the application stroke will be dependent on the absorbency of the surface being coated, slow for absorbent, fast for non-absorbent. The only way of determining the correct speed is by practice and experience. GRAFFITI - PRUF is effective with one single coat, provided that coat is properly applied, with complete coverage achieved.

NOTE: When dry, GRAFFITI - PRUF is almost invisible. If a job is being left partly completed, it is important that the finishing point be clearly indicated. If in doubt, coat again as any double coating will not be seen.

(F) GRAFFITI - PRUF may be applied by brush or roller. This is recommended only on smooth surfaces. On textured surfaces, all areas may not be properly coated unless extreme care is taken.
