with dry wall mud paddle mixer Note: An in-line static mixer must also be utilized Static Mixer Specification:: Standard 12 turn, 3/4" ID

15

SURFACE PREPARATION

Surface must be grit blasted to SSPC-SP6 (Sa 2) for onshore applications and SSPC-SP10 (Sa 2 1/2) for offshore applications with a minimum profile of 1.5 to 2.0 mils. Only approved primers shall be utilized. If an existing primer is utilized, and is not on the approved primer list, it must be accepted by Nu-Chem in writing. Contact Nu-Chem for approved primer list. Prior to the application of THERMO-LAG 3000, all surfaces must be clean, dry and free of contamination.

16

MASKING OF BLOCKOUTS

THERMO-LAG 3000 Will Bond To Most Surfaces

Mask off blockout surfaces with polyethene sheeting - held in place by tape After THERMO-LAG 3000 application is complete, remove masking before full cure Do not use release agents!!!

22

THERMO-LAG 3000 FIRST COAT

Set Target Thickness

• Depends on mesh type/position and final thickness requirements

• Do not exceed 200 mils (5mm) for any coat

Monitor, check and record thicknesses and environmental conditions

23

THERMO-LAG 3000

Reinforcement

Installed into wet THERMO-LAG 3000

• Roll into surface of wet material • Thoroughly embed mesh with a solvent

moistened roller or trowel • Mesh must be covered with the next coat of

THERMO-LAG 3000 prior to the end of the working day

• See application manual (latest revision) for specific application details, overlaps, etc.

24

THERMO-LAG 3000 SUBSEQUENT COATS

Do not exceed recoat window!!! • Wet-on-wet application is always best • If recoat window is exceeded, refer to application

manual (latest revision)prior to the continuation of the application

• Complete THERMO-LAG 3000 application – no pin holes

25

FINAL THICKNESS CHECKS

Final thicknesses must be checked, recorded and meet project specifications

26

TOPCOATING • Topcoat is required for all applications • THERMO-LAG 3000 must be protected from rain prior to topcoat

application • Epolon II (or equivalent)

@ 6 mils (150 microns) minimum DFT • Observe topcoat recoat times
