Product Use Instructions
Surface Preparation
General: Surface should be clean and free of contamination such as greases, oils, or other residues. Clean with detergent wash or pH neutralizing agents then flush with fresh water. Abrasive blast metals to SSPC-SP10 “Near White Blast” standards with a 2-4 mil anchor profile to provide optimal adhesion performance.
Splashzone: Remove marine biological settlement and corrosion by high pressure water jetting with or without abrasive. Conventional air/abrasive blasting works well at shallow depths, however, efficiency falls off sharply below 10 feet. Hand held power tools such as needle guns or grinders can give good results in small areas. Apply within 45 minutes after surface preparation to minimize rusting or resettlement of biological fouling which interferes with adhesion.
Mixing Procedures
This material is a two-component product, premeasured to produce the desired kit size once part A and B are mixed. For small kits, a Jiffy type mixer with a high torque motor is recommended for proper blending. Pour the curing agent into the base and mix for about 1 minute, taking care to reach all corners and walls to eliminate unmixed material. Unmixed material will never harden. Material may immediately be used. For larger areas, application by heated plural spray should use the following equipment setup:
Mix ratio: 2/1 by volume
Fluid Pressure: 2,500 psi
Fluid Temp (A and B): 120 – 140°F
Tip Size: .021” – .033”
Application
When applying as a tank lining, prepare the surface and apply an initial heavy “stripe coat” to all welds and sharp edges by brush or roller. Allow this stripe coat to cure until “gummy” before full coat application.
No primer needed on metallic surfaces.
Low viscosity primer recommended for concrete applications to penetrate and seal concrete first.
40 mil single coat application. Increased mil thickness will stiffen the coating and reduce flexibility.
For existing coatings/ liners, ensure combability with Exterior Performance Coatings representative. Reach out at 630-675-4509 or sales@exteriorcoatings.com. If allowed, tightly adhered coatings are typically ok to coat over given they are mechanically prepared to create a rough profile for improved coating adhesion.
Bio-Dur E3050 may be immersed in fresh or salt water immediately after application. It will cure to a hard film within 24 hours and is suitable for traffic after this time. Allow at least three (3) days at 77F before subjecting to aggressive chemical servcie from industrial solvents or similar materials.
If pinholes are witnessed or found during holiday detection, clean and abrade the affected area. Recoat with addition Bio-Dur E3050 and allow to cure before returning to service.
Note:
Steel mixing container, 26”x26” diameter, surface area =
Nitric acid, sulfuric acid, hcl @20%, 170°F, 24hour immersion followed by 5 hour free.
- Nitric acid is most severe, typically only tested to 10% and can cause swelling
