Remove all oil, dust, grease, dirt, loose rust, and other foreign material to ensure adequate adhesion. Masonry and Block Surfaces should be thoroughly clean and dry. Concrete and mortar must be cured at least 28 days @ 75 ° F. Remove all loose mortar and foreign material. Surface must be free of laitance, concrete dust, dirt, form release agents, moisture cur- ing membranes, loose cement and hardeners. Poured Concrete New Surface must be clean, dry, sound, and offer sufficient profile to achieve adequate adhesion. Minimum substrate cure Is 28 days at 75 ° F. Remove all form release agents, curing com- pounds, salts, efflorescence, laitance, and other foreign mat- ter by sandblasting, shotblasting, mechanical scarification, or suitable chemical means, such as muriatic acid etch, refer to ASTM 04260. Rinse thoroughly to achieve a final pH between 6.0 and 10.0. Allow to dry thoroughly prior to coating. Old Surface preparation is done in much the same manner as new concrete; however, if the concrete is contaminated with oils, grease, chemicals, etc., they must be removed by cleaning with a strong detergent. Refer to ASTM D4258. Form release agents, hardeners, etc. must be removed by sandblasting, shot - blasting, mechanical scarification, or suitable chemical means. If surface deterioration presents an unacceptably rough sur- face, Kem Cati -Coat HS Epoxy Filler /Sealer Is recommended to patch and resurface damaged concrete. Fill all cracks, voids and bugholes with ArmorSeal Crack Filler. Always follow the ASTM methods listed below: ASTM D4258 Standard Practice for Cleaning Concrete.

IH -35, Suite 300 Austin, Texas 78741 Attn: Mr. Brad Castleberry Re: Water System Improvements Contract No. 1 — Elevated Water Storage Reservoirs City of Round Rock, Texas Dear Sir: LAN ID MAR K Per your request, I am providing a breakdown of costs related to Change Proposal Request No. 5. The total area to be covered is approximately 2015 square foot based on a coverage height of 15 foot above grade. I have spoken with Mr. Bob Bridendolph of Sherwin Williams in order to get the pricing and coverage per gallon. The quantities below are based on the information from Bob. Urethane (B65WJ) 18 Gallons at $39.00 /Gallon (2 coats) 702.00 Block Filler (Kem Cati -Coat HS) 30 Gallons at $21.00 /Gallon 630.00 Labor to Install $2.00 /Sq. Ft. 4,030.00 OH & P 10% 535.00 5,897.00 Total Cost CPR No. 5for both tanks $11,794.00 Landmark does not recommend using Anti - Graffiti Coatings, because we found that it will discolor the concrete. Epoxy Block Filler will be "off- white" and this will not match the concrete. We recommend to leave the blasted concrete finish for one year and after that time determine if an anti - graffiti coating is necessary. Another consideration prior to applying a coating to the pedestal is that you will create an additional maintenance requirement. We know of only one of our tank pedestals that has been used by a graffiti artist after construction was complete; the graffiti in this case was removed by a light sandblast. Please let me know if you need any additional information on these items. Yours very truly, LANDMARK STRUCTURES, INC.

Clean spills and spatters immediately with Reducer 4145. R7K145. Clean tools immediately after use with Reducer 8145, R7K145. Follow manufacturers safety recommendations when using any solvent. When using spray application, use a 50% overlap with each pass of the gun to avoid holidays, bare areas, and pinholes. If necessary, cross spray at a right angle. Spreading rates are calculated on volume solids and do not include an application Icss factor due to surface profile, rough- ness or porosity of the surface, skill and technique of the ap- plicator, method of application, various surface irregularities, material lost during mixing, spillage, overthinning, climaticcon- ditions, and excessive film build. Excessive reduction of material can affect film build, appear- ance, and adhesion. Do not apply the material beyond recommended pot life. Do not mix previously catalyzed material with new. Depending on condition of substrate, more than one mat may be required. Do not apply under 50 sq ft/gal or mudcracking may occur. Not recommended for previously painted surfaces. Temperatures above 77'F will shorten pot life. For best results, apply by airless spray and immediately back roll. Do not apply over moisture, or below 45 °F.
