Drying and Recoating Times
| Substrate temp. | Touch dry | Dry to handle | Full cure | Dry to recoat Min. | Maximum (1) |
| 10°C | 12 hours | 48 hours | 10 days | 36 hours | 4 days |
| 23°C | 6 hours | 24 hours | 7 days | 24 hours | 2 days |
| 30°C | 4 hours | 18 hours | 4 days | 16 hours | 1 day |
(1) The surface should be dry and free from contaminants prior to overcoating. When the maximum recoating time is exceeded it may be necessary to roughen the surface to ensure intercoat adhesion. When in doubt, consult your nearest Navimare-PX office.
Surface Preparation
Steel: Oil and grease should be removed by solvent cleaning according to SSPC-SP1. Remove weld spatter and smooth weld seams and sharp edges as applicable. Abrasive blasting: min. Sa2.5 – ISO 8501:1. Roughness profile: 50–75 micron. Remove all loose dirt and abrasive by vacuuming or sweeping. Apply Navimar Tankguard immediately after the steel has been blasted and the quality of preparation has been approved.
Recommended Paint System
A typical system is shown below.
Navimar Tankguard 471: 2 x 200 µ dft.
Sharp edges, corners and weld seams must be stripe coated in order to achieve the specified dry film thickness.
