4.0 PROCEDURE 4.1 PREPARATION OF SUBSTRATES AND COATING MATERIALS 4.1.1 Preparation of Surfacer 4.1.1.1 Normal surface preparation shall consist of water blasting with 4,000 P.S.I. to 10,000 P.S.I.
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 recom-mended solution, or straight sand blasting. Any heavy oil or grease deposits shall be removed by steam oleaning, trisodium phosphate J
washing with a mixture of 3-6 pounds T.S.P. per gallon of water, or use of an Imperial recomended 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 j
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 dry-pack or epoxy grout.
Detrimental surface irreg-i l
ularities such as projections, fins, or ridges shall be reduced by bush-hamering, power grinding, or stoning. Wood particles of
" fuzz" remaining after water blasting is acceptable.
Recomended I
surface preparation shall include power tools which are capable of removing liatance and curing membranes from concrete' surfaces, i
4.1.1.2 Markings on concrete - Before application of 115,11 or 1201, all markings (ink, pencil, chalk, or felt tip markers) on wall and floors shall be solvent wiped in accordance with SSPC-SP-1 using DL-6A or comercially 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 discoloration 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, bolts, wood, or plastic shall be repaired per the following guidelines before application of NUTEC 115 surfacer.
1.
Objects protruding from the surface shall be ground or cut smooth until thq object is flush with the concrete surface prior to application of 115.
1 2.
If the object is loosely adhered in the concrete, it shall be removed (in case of wook splinters or wood " fuzz" an i
attempt shall be made to remove by high pressure water blast-ing).

3.3.2 Mixing instructions - slowly mix by power agitation or by hand the entire volume of the cure component with the entire volume of the base.
If an accelerator is used, add thepremeasured portion j
to the base-cure mix and mix slowly.
Avoid rapid agitation which may result in air entrapment.
Do not vary proportions.
i 3.3.3 Thin the NUTEC #10 mix with 10-40% #DL-56 solvent (Cellosolve).
Thinning minimizes air entrapment, eliminates film irreglarities, enhances penetration, and prolongs the pot life of the material.

l 3.3.7 NUTEC #10 has a pot life of approximately I hour (at 75*F).
I 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. All 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 410 (expired) shall be discarded.
Caution:
Storage of NUTEC #10 containers at high temperatures or in direct sunlight will greatly reduce its pot life.

NOTE:
Po t life stated above for unthinned coating is the recommended I
time and should be used as a guideline for coating usage time, however, actual pot life may be longer.
For unthinned coating i
