EverSeal has excellent resistance to moisture penetration, adhesive bleed -through from latex -based adhesives, and dust and oil contamination. It is ideal for use in sensitive environments; it has very low odor and low VOCs (volatile organic compounds) and contains and antimicrobial agent. EverSeal is designed for use with all Lees' installation products: Lees Wet Set Adhesive. Lees Squared Pressure Sensitive Adhesive, Lees Thermntapc, and Leas NeoFloor Adhesive. EverSeal is packaged in four -gallon containers; spread rate is approximately 40 yards per gallon per coat. One Coat of EverSeal is Recommended for the Following Conditions: Dusty Sabfioors - EverSeal .seals out dusty. dirty subfloors. pmviding a clean substrate cm which to install any of the Lees adhesives and carpet products. EverSeal will also seal Cryperete patches and oil contamination over wood subfloors. Porous Suhftoors - EverSeal will seal porous subfloors, preventing the loss of adhesive into the subfloor. Porous subfloors can include unsealed concrete or hardwood, or plywood subfloors. EverSeal will also seal concrete patching compounds. Latex -based Adhesives - Lees EverSeal is guaranteed to seal any existing latex. adhesive residue that may remain on the subfloor. EverSeal serves as a barrier between the old and new adhesives to prevent bleed -through or reactions with the new adhesive. EverSeal will also deaden residual adhesive tack to provide easier installation of the new carpet. NOTE: Lees EverSeal is not warranted for use aver cut -back or black solvent -based adhesives. To seal old cut•buck or black solvent-basrd adhesives, use Zees SureSeal subfloor sealer. Two Coats of EverSeal Are Required for the Following Conditions: Elevated pH (Alkalinity) Levels—.EverScal will provide a harrier coat to prevent alkaline salts in the slab from reacting with the adhesive_ If the pH level of the subfloor is between 9 and 14, mop the floor with a vinegar and water solution (eight ounces of vinegar to one gallon of water) to remove alkalinity on the surface of the slab. Allow this solution to dry completely, then use two coats of Lees EverSeal to seal the surface of the concrete (see EverSeal installation instructions). • 03/31/2005 12:15 0584862517 JJJFLOORCOVERING RAGE 05 Elevated Moisture Levels - EverSeal is recommended for any subfloor with a calcium chloride test result up to 8 pounds of moisture per 1.,000 square feet per 24 hours when used with Lees Wet Set Adhesive. installations using pressure sensitive adhesives, tape systems, or any of Lees' other adhesive systems cal be protected up to 8 pounds of moisture when using lees EverSeal. However- tees Technical Service must be consulted if the moisture reading is above 5 pounds for these types of installations_ Lees will assist the contractor in determining the best application method based on site conditions. If two coats of EverSeal are applied, with both coats receiving 24 hours of curing time, EverSeal is guaranteed for the lifetime of the carpet as a moisture barrier between the subfloor and Lees adhesives. Please note that the calcium chloride test measures moisture, not hydrostatic pressure. EverSeal is not guaranteed against hydmstatic pressure. Warranty When used according to instructions and in conjunction with Lees' carpets and adhesives, the Lees Lifetime Warranty extends to the adhesive bond of the carpet to the subfloor. This warranty covets EvcrS al's ability seal out moisture emission up to 8 pounds per I,000.square feet per 24 hours as measured by a calcium chloride test (ASTM F 1869-98) when used with Lees Adhesives. (For adhesives other than Lees Wet Set, contact Lees Technical Service if the moisture reading is between 5 and 8 to determine the hest application method.) If the moisture level is over the rcommendcd limits, other means trust be employed to curtail .moisture emissions before installation. NOTE: Lees Technical Service must be consulted if the moisture reading Is above 5 pounds for the types of installations. Lees will assist the contractor in determining the best application method based on sight conditions. EverSeal is also warranted to also stop alkaline salts from rising to the .surface of the slab, providing the slab is cleaned with the vinegar and water solution before application. Also, EverSeal is guaranteed to deaden old adhesive residual tack and seal dusty or porous plywood and concrete floors. Note: EverSeal must be applied to bare, clean concrete to serve as moisture barrier. For this warranty to apply, documentation of temperature and humidity at the time of application must be sent to Lees Technical Services. If using EverSeal to correct a moisture problem, ealdum chloride test results must also be sent to Lees Technical Services, along with the sine of the installation and the amount of EverSeal purchased, either through a copy of the invoice trom Lees Customer Service or documentation from the Lees authorized dealer where the EverSeal was purchased. Lees also requires documentation of purchase of a Lees Adhesive. Send documentation to: Lees Technical Service, Attn: EverSeal. Warranty, 65 East Ferguson Avenue, Wood River, IL 62095. This warranty covers full replacement of material and reasonable labor costs for the affected installation. This guarantee only covers those installations where a Lees' adhesive product and Lees' floor covering are being installed over Lees EverSeal. The Lees warranty does not cover those installations where Lees floor coverings and Lees' adhesives are net used. CAUTION! EverSeal cannot be used over chemically cleaned sub -floors. 03/31/2005 12:15 8584862517 JJJFLOORCOVERING PAGE 06 LEES EVERSEAL MATERIAL SAFETY DATA SKEET FOR FLOOR COVERING ADHESIVES DATE OF PREPARATION: 08-28-03 SECTION T Manufactured for: Lees Carpets * 3300 W.

AEETING DATE May 3, 2005 City of National City, California COUNCIL AGENDA STATEMENT AGENDA ITEM NO. 7 ITEM TITLE Resolution of the City of National City Approving Change Order Number Eighteen with Marcotte and Hearne Builders for the installation of a concrete vapor sealer on the slab grade of the building for the Fire Station Project in the total amount of $8,392 and authorizing the City Engineer to sign the change PiigVARED BY DEPARTMENT Stephen Kirkpatrick EXPLANATION See attached explanation. Engineering EXT. 4383 Environmental Review X N/A Financial Statement Approved By: BOARD / COMMISSI RECOMMENDATION N/A Finance Director ATTACHMENTS (Liisted Below ) 1. Resolution 2. Change Order Number Eighteen Resolution No. 2-0OS - g n 200 0.00� EXPLANATION: The fire station has vinyl tile, rubber mats, and carpet installed as flooring throughout the meeting rooms and living areas. These flooring items are glued directly on the slab on grade. This area is a total of 6,100 square feet. In order to install these products and warranty the installation it is necessary to have vapor emissions below industry standard levels. Vapor emissions are determined through an ASTM test known as Calcium Chloride emission testing. Calcium chloride vapor emissions can often be seen on concrete in the form of efflorescence — a loose white chalky substance on the concrete. The specifications do not require that a vapor barrier be installed. When the project was designed it was believed that the anticipated construction schedule would allow the slab on grade to be poured early, and it would dry to an acceptable level by the time these floorings were installed. Paying for a vapor barrier was thought to be an unnecessary expense. The slab was poured in August of 2004 as anticipated, however, due to the topography of the site and the record amount of rainfall that has occurred this year; the slab has not dried as anticipated. in order to properly install these flooring materials it is necessary to install this vapor barrier. This barrier will ensure the integrity of the concrete surface, prevent the efflorescence, and limit any degradation of the glue and the flooring product installed. RESOLUTION NO. 2005 —81 RESOLUTION OF THE CITY COUNCIL OF THE CITY OF NATIONAL CITY AUTHORIZING THE CITY ENGINEER TO EXECUTE CHANGE ORDER NO. 18 WITH MARCOTTE & HEARNES BUILDERS, INC. FOR THE INSTALLATION OF A CONCRETE VAPOR SEALER ON THE SLAB GRADE OF THE BUILDING FOR THE FIRE STATION PROJECT IN THE TOTAL AMOUNT OF $8,392 WHEREAS, the contract for the Fire Department Construction Project was awarded to Marcotte & Heames Builders, Inc. on February 17, 2004, by the adoption of Resolution No. 2004-31; and WHEREAS, due to the topography of the site and the record amount of rainfall this year, the 6,100 square foot slab of the building has not dried as anticipated, requiring the installation of a vapor sealer on the slab grade of the building before the flooring materials are laid. NOW, THEREFORE, BE IT RESOLVED that the City Council of the City of National City hereby authorizes the City Engineer to execute Change Order No. 18 with Marcotte & Heames Builders, Inc. in the total amount of $8,392 for the installation of a vapor sealer on the slab grade of the building for the construction of the fire station project.

EverSeal has excellent resistance to moisture penetration, adhesive bleed -through from latex -haled adhesives, and dust and oil contamination. It is ideal for use in sensitive environments; it has very low odor and low VOCs (volatile organic compounds) and contains and antimicrobial agent. EverSeal is designed for use with all Lees' installation products' Lccs Wet Set Adhesive. Lees Squared Pressure Sensitive Adhesive, Lees Thermotape, and Lees NeoFloor Adhesive. EverSeal is packaged in four -gallon containers; spread rate is approximately 40 yards per gallon per coat. One Coat of EverSeal Is Recommended for the Following Conditions: Busty subfloors - EverSeal seals out dusty. dirty subfloors. providing a clean substrate an which to install any of the Lees adhesives and carpet products. EverSeal will also seal Cryperete patches and oil contamination over wood subfloors. Porous Suhfloors - EverSeal will seal porous subfloors, preventing the loss of adhesive into the subfloor. Porous subfloors can include unsealed concrete or hardwood, or plywood subfloors. EverSeal will also seal concrete patching compounds. Latex -based Adhesives - Lees EverSeal is guaranteed to seal any existing latex adhesive residue that may remain on the subfloor. EverSeal serves as a barrier between the old and new adhesives to prevent bleed -through or reactions with the new adhesive. EverSeal will also deaden residual adhesive tack to provide easier installation of the new carpet. NOTE: Lees EverSeal is not warranted for use over cut -back or black solvent -based adhesives. To seal old cut -hack or black solver( -based adhesives, use Lees SureSeal ardhfloor seater. Two Coats of EverSeal Are Required for the Following Conditions: Elevated pH (Alkalinity) Levels — EverSeal will provide a harrier coat to prevent alkaline salts in the slab from reacting with the adhesive_ If the pH level of the subfloor is between 9 and 14, mop the fkx,r with a vinegar and water ,solution (eight ounces of vinegar to one gallon of water) to remove alkalinity on the surface of the slab. Allow this solution to dry completely, then use two coats of Lees EverSeal to seal the surface of the concrete (see EverSeaJ installation instructions). 03/31/2005 12:15 8584862517 JJJFLOORCOVERING PAGE 05 Elevated Moisture Levels - EverSeal is recommended for any subfloor with a calcium chloride test result up to 8 pounds ofmnisrure per 1,000 square feet per 24 hours when used with Lees Wet Set Adhesive. Installations using pressure sensitive adhesives, tape systems, or any of Lees' other adhesive systems can be protected up to 8 pounds of moisture when using Lees EverSeal. However. Lees Technical Service must he consulted if the moisture reading is above 5 pounds for these types of installations. Lees will assist the contractor in determining the best application method based on site conditions. Tf two coats of EverSeal are applied, with both coats receiving 24 hours of curing time, EverSeal is guaranteed for the lifetime of the carpet as a moisture harrier between the subfloor and Lees adhesives. Please note that the calcium chloride test measures moisture, not hydrostatic pressure. EverSeal is not guaranteed against hydmstatic pressure. Warranty When used according to instructions and in conjunction with Lees' carpets and adhesives, the Less Lifetime Warranty extends to the adhesive bond of the carpet to the subfloor. This warranty covers EvcrSeal's ability seal out moisture emission up to 8 pounds per 1,000 square feet per 24 hours as measured by a calcium chloride test (ASTM F 1869-98) when used with Lees Adhesives. (For adhesives other than Lets Wet Set, crmtact Lecs Technical Service if the moisture reading is between 5 and 8 to determine the best application method.) If the moisture level is over the recommended limits, other means roust be employed to curtail .moisture emissions before installation. NOTE: Lees Technical Service must be consulted if the moisture reading is above 5 pounds for these types of installations. Lees will assist the contractor in determining the test application method based on sight conditions. EverSeal is ai.so warranted to also stop alkaline salts from rising to the surface of the slab, providing the slab is cleaned with the vinegar and water solution before application. Also, EverSeal is guaranteed to deaden old adhesive residual tack and seal dusty or porous plywood and concrete floors. Note: EverScal mast be applied to bare, clean concrete to serve as moisture barrier. For this warranty to apply, documentation of temperature and hnmldity et the time of application must be sent to Lees Technical Services. If using EverSeal to correct a moisture problem, calcium chloride test results must also be sent to Lees Technical Services, along with the sine of the installation and the amount of EverSeal purchased, either through a copy of the invoice from Lees Customer Service or documentation from the Lees authorized dealer where the EverSeal was purchased. Lees also .requires documentation of purchase of a Lees Adhesive. Send documentation to: Lees Technical Service, Attn: EverSeal Warranty, 65 East Ferguson Avenue, Wood River, IL 62095. This warranty covers full replacement of material and reasonable labor costs for the affected installation. This guarantee only covers those installations where a Lees' adhesive product and Lees' floor covering are being installed over Lees EverSeal. The Lees warranty does not cover those installations where Lees floor coverings and Lees' adhesives are not used. CAUTIONI EverSeal cannot be used over chemically cleaned sub -floors.
