performance tips

Stripe coat all crevices, welds, and sharp angles to prevent early failure in these areas.
When using spray application, use a 50% overlap with each pass of the gun to avoid holidays, bare areas, and pinholes. If necessary, cross spray at a right angle. Spreading rates are calculated on volume solids and do not include an application loss factor due to surface profi le, roughness or porosity of the surface, skill and technique of the applicator, method of application, various surface irregularities, material lost during mixing, spillage, overthinning, climatic conditions, and excessive fi lm build.
Excessive reduction of material can aff ect fi lm build, appearance, and adhesion. Do not apply the material beyond recommended pot life. Do not mix previously catalyzed material with new. In order to avoid blockage of spray equipment, clean equipment before use or before periods of extended downtime with Reducer #58. Mixed coating is sensitive to water. Use water traps in all air lines. Moisture contact can reduce pot life and aff ect gloss and color.
