Lower metal temperatures will slow the dry time and higher metal temperatures will speed up dry time
Product is ready for holiday testing as soon as it reaches its dry-to-handle state
Maximum recoat time with Carbothane series is 28 days
Maximum recoat with itself is two hours
To topcoat after the maximum recoat time, the surface must be cleaned to remove all contaminants per SSPC-SP1
Then abrade to create a roughened surface
Remove dust and debris prior to coating
Surface Preparation
Preparation
Steel:
Remove all contaminants per SSPC-SP1
Abrasive blast to NACE No. 2/SSPC-SP 10 and create 3 to 5 mil (75 to 125 µ) dense angular anchor profile
Remove dust and debris after blasting
Apply Polyclad 777 R prior to any flash rusting or contamination
Patching and Repair Instructions:
Small areas of bare steel may be prepared by power tool cleaning to bare metal and creating dense angular profile in accordance with SSPC-SP 11. Feather edge into adjoining sound coating 3 to 6 inches where the repair coating will be overlapped and create a roughened surface by brush-off blast cleaning in accordance with NACE No. 4/SSPC-SP 7, or by hand or power tool cleaning per SSPC-SP2/SP3
Application Methods
Product Information
Brush and Roller:
Apply to area to be coated
Spread using a no-shed 3/8" roller or brush to the proper thickness
Dual Cartridge:
Heat cartridges to 43-49°C
Place in dual cartridge gun and add static mixer.
Use atomized air set at 40-60 psi as needed.
Set delivery speed to medium fast
Spray the first small portion to waste or off target test area Spray prepared substrate with the crosshatch pattern to the desired thickness
Single Cartridge:
Designed for very small repairs only
Will need extra static mixers if cartridge is going to be used more than once
To use place cartridge in manual caulking gun. Squeeze until mixed material comes out of the static mixer
Immediately spread over the repair area using a no-shed 3/8" roller or brush to the proper thickness
