Additionally, surface preparation may be accomplished by the use of approximately 2,500 P.S.I.
water blasting with sand injection, acid etching with an Imperial recommended solution, or straight sand blasting. Any heavy oil or grease deposits shall be removed by steam cleaning, trisodium phosphate washing with a mixture of 3-6 pounds T.S.P. per gallon of water, or use of an Imperial recommended detergent.
Following surface preparation, the surface shall be free of construction dust, laitance, and loose deposits.
If cleaning does not remove oil and grease, the contaminated concrete surface will be chipped away and patched before coating.
All T.S.P. cleaned areas will be flushed with clean water. Holes or voids in the concrete surface that exceed 1/2" in depth shall be repaired with drypack or epoxy grout. Detri= ental surface irreg-ularities such as projections, fins, or ridges shall be reduced by bushhammering, power grinding, or stoning. Wood particles of
" fuzz" remaining af ter water blasting is acceptable. Recommended surf ace preparation shall include power tools which are capable of re=oving liatance and curing membranes from concrete surfaces.
4.1.1.2 Markings on concrete:
Before application of IIS, 11 or 1201, all carkings (ink, pencil, chalk, or felt tip markers) on wall and floors shall be solvent wiped in accordance with SSPCSPL using DL6A or commercially available MEK or Xylol. Marking paint (surveyor marks) shall be removed by solvent wiping, water blasting, sandblasting, or power tool cleaning. Discolored coatings due to aging or stains shall be abraded and solvent wiped to remove the discoloration. Residual marking or dis-coloration remaining in pores below the plane of the surface is acceptable.
4.1.1.3 Repair of embedded foreign objects: Embedded foreign objects such as nails, rebar chairs and plastic endcaps on rebar chairs, bolts, wood, or plastic shall be repaired per the following guidelines bef, ore application of the surfacer.

3.2.3 Brush 3.2.3.1 A clean, high quality brush may be used to coat small areas or concrete inaccessible for spraying.
3.2.4 Roller 3.2.4.1 A short to esdium knap roller shall be used.
3.3 APPLICATION 3.3.1 Flush equipment with Imperial's #DL-6A Universal Solvent or imperials dDL-56 (cellosolve) Solvent prior to use.
3.3.2 Mixing instructions - slowly mix by power 46ttation or by hand the entire volume of the cure component with the entire volume of the baso.
If an accelerator is used, add thepremeasured portion to the base-cure mix and mix slowly. Avoid rapid agitation which may result in air entrapment. Do not vary proportions.
3.3.3 Thin t.he NUTEC #10 mix with 10-40% #DL-56 solvent (Cellosolve).
Thinning minimizes air entrapment, eliminates film irreglarities, enhances penetration, a'nd prolongs the pot life of the natorial.
3.3.4 As a guide, if using conventional spray, regulate the air pressurer 60-80 psi to gung 10-20 psi to pot.
NOTE:
Required pressures may vary with temperature of hose length.

03/0./84 5 of 5 ATTACHMENT 5 3.3.5 As a guide, during spray application, apply material as a heavy, wet coat, in even, parallet passes overlapping each pass by 50%
3.3.6 Apply NUTEC #10 at a spreading rate of approximately 350-400 sq. ft./ gal. Avoid excessive build up which will cause a
" glazing" affect after drying.
3.3.7 NUTEC #10 has a pot life of approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> (at 75'F).
No material shall be applied which has exceeded its pot life.
If this has occured, there is an increase in the viscosity of the material, a noticeable heat of exotherm and applied material will " crawl" and refuse to penetrate the concrete. A11 material thus applied shall be removed from the concrete with solvent and a clean cloth. All equipment shall be cleaned immediately and any remaining NUTEC fl0 (expired) shall be discarded. Caution:
Storage of NUTEC #10 containers at high temperatures or in direct sunlight will greatly reduce its pot life.
NOTE:
Pot life stated above for unthinned coating is the recommended time and should be used as a guideline for coating usage time, however, actual pot life may be longer.
For unthinned coating or coatina thinned less than 50%, the actual pot itfe is determined by applicability of the coating.
3.3.8 During application all areas found to contain sags, surface irregularities, or excessive buildup of NUTEC #10 shall be removed with solvent and a clean cloth and fresh NUTEC #10 applied.
3.3.9 Flush Spray equipment periodically with Imperial's DL6A Solvent or DL-56 to avoid build up of material in the hoses.
3.3.10 Clean up all equipment immediately following application with Imperial's #DL-56 cellosolve solvent or Imperial's #DL-6A Universal Solvent.
NOTE:
1.
Do not apply NUTEC #10 curing compound to surfaces which visible surface moisture or standing water is prosent.
2.
Refer to manufactures product data sheet for general info rma tion.
3.
Material may be applied at temperatures above 80'F.
When applications are made at temperatures above 80*F care must be taken to assure pot life not exceeded.
