3.1.2 Penetrations

Verify items which penetrate surfaces to receive fluid-applied roof membrane are securely installed.

3.2 PREPARATION

3.2.1 General

Coordinate work with that of other trades to ensure that components to be incorporated into the fluid-applied roof membrane system are available when needed. Inspect and approve surfaces immediately before application of materials. Remove sharp projections, grease, oil, dirt, and other contaminants which could adversely affect the complete bonding of the fluid-applied roof membrane system.

3.2.2 Protection

Protect adjacent surfaces to receive other finishes.

3.3 TREATMENT OF ROOF PENETRATIONS

Seal around and along all perimeters of penetrations with elastomeric sealant as recommended by the fluid-applied roof membrane manufacturer.

Seal all joints and cover with application of base coat, reinforcing and second base coat to saturate the fabric.

3.4 APPLICATION

3.4.1 Application Over Concrete

3.4.1.1 Prime Coat

Apply prime coat of acrylic bonding agent, cement, and water in proportions and rate as recommended by the fluid-applied roof membrane manufacturer.

3.4.1.2 Base Membrane

Apply base coat membrane using a roofing brush spray, squeegee, or roller in one uniform coat at approximately rate of 4.0 gallon per 100 square feet minimum or as recommended by the fluid-applied roof membrane manufacturer. Embed reinforcing fabric into coating while still wet.

Follow with additional base coat saturation coat to fully cover fabric.

Allow 16 to 36 hours curing time before applying the next coat.

SECTION 07 56 00 (AMD 000 3) Page 6

3.4.1.3 Top Coat Membrane

After curing of the base membrane, apply the top coats in a minimum of two coat application at an approximate total rate of 2.0 gallon per 100 square feet minimum. First coat shall be white and second coat shall be custom color as indicated. Provide additional custom colored coating to fully cover the white first coat.

3.4.1.4 Total Thickness

The overall dry film thickness of the completed roof membrane system shall average 60 mils, not including skim coat with broadcast white ceramic granules.

3.4.2 Skim Coat with Ceramic Granules and Backrolled Finish Coat

Wait a minimum of 4 hours depending on drying conditions and then apply a skim coat of top coat membrane at an approximate rate of 1.0 gallon per 100 square feet minimum and broadcast white ceramic granules at a minimum rate of 30 to 50 pounds per 100 square feet and backroll with top coat membrane or otherwise recommended by manufacturer.

3.5 FIELD QUALITY CONTROL

3.5.1 Moisture Test

Prior to application of fluid-applied roof membrane, measure moisture content of substrate with a moisture meter in the presence of the Contracting Officer. An acceptable device is the Delmhorst Moisture Meter, Model BD7/2E/CS, Type 21 E. Similar meters by other manufacturers, which are suitable for the purpose, may be used as approved by the Contracting Officer. Do not begin application until meter reading indicates "dry" range.

3.5.2 Film Thickness

Measure wet film thickness every 100 square feet during application by placing flat metal plates on the substrate or using a mil-thickness gage especially manufactured for the purpose.

3.5.3 Instructions to Government Personnel

Furnish written and verbal instructions to designated Government personnel. Instructions shall be given by a competent representative of the fluid-applied roof membrane manufacturer and shall include a minimum of 4 hours on maintenance and emergency repair procedures. Include a demonstration of membrane repair, and give sources of required special tools. Furnish information on safety requirements during maintenance and repair operations.
