3.8

FLASHING APPLICATION

General:

Install cold fluid-applied reinforced (PM MA) methyl-methacrylate waterproofing flashing system in accordance with the requirements/recommendations of the membrane manufacturer and as depicted on standard drawings and details. Provide system with base flashing, edge flashing, penetration flashing, counter flashing, and all other flashings required for a complete watertight system.

Wherever possible, install the flashings before installing the field membrane to minimize foot traffic over newly installed field membrane.

All membrane flashings shall be installed concurrently with the waterproofing membrane as the job progresses. Temporary flashings are not allowed without prior written approval from the membrane manufacturer. Shall any water penetrate the new waterproofing membrane because of incomplete flashings; the affected area shall be removed and replaced at the installer's expense.

Provide a minimum vertical height of 8 inches (203 mm) for all flashing terminations. Flashing height shall be at least as high as the potential water level that could be reached as a result of a deluging rain and/or poor slope. Do not flash over existing through-wall flashings, weep holes and overflow scuppers.

All flashings shall be terminated as required by the membrane manufacturer.

Alsan RS 230 Flash resin is alkalinity resistant. Additional bond/wearing layer consisting of one application of Alsan RS 230 Flash on vertical surfaces and one application of approved broadcast mineral aggregate surfacing shall be applied wherever stone, concrete, or masonry elements will be placed directly over the flashing.

Application of Resin/Fleece:

Apply mixed resin to the prepared surface at the approximate rate of 0.19 kg/sf (2.0 kg/sq. m). The resin shall be rolled or brushed liberally and evenly onto the surface using a broad, even stroke. Cover one working area at a time, between 2 to 5 sf (0.19 to 0.46 sq. m).

Roll out dry polyester fleece onto the liquid resin mix, making sure the SMOOTH SIDE IS FACING UP (natural unrolling procedure), avoiding any folds and wrinkles. The fleece will begin to rapidly saturate with the liquid resin mix. Use a medium nap roller or brush to work the resin into the fleece, saturating from the bottom up, ensuring that all angle changes points are tight and not bridged and eliminating air bubbles, wrinkles, etc. The appearance of the saturated fleece shall be light opaque amber with no white spots. White spots are indications of unsaturated fleece or lack of adhesion. It is important to correct these faults before the resin cures.

Apply additional liquid resin mix on top of fleece at the approximate rate of 0.12 kg/sf (1.3 kg/sq. m) to finish the saturation of the fleece. Roll this final coating into the fleece, which will result in a glossy appearance. The fleece can only hold so much resin and all excess shall be rolled forward to the unsaturated fleece, eliminating ponding or excessive build-up of the resin. Any excess resin left on the top of the fleece will weather and peel off. The correct amount of resin will leave no whiteness in fleece and there will be a slightly fibrous surface texture. The final resin coating shall be smooth and uniform.

Prevent contact between mixed/unmixed resin and new/existing membrane. If any unmixed resin contacts membrane surface remove immediately and clean thoroughly with a cloth rag.

At all fleece seams, allow a 2 inches (51 mm) overlap for all side joints and a 4 inches (102 mm) overlap for all inside and outside corner overlaps.

At membrane tie-offs, clean in-place membrane with Alsan RS Cleaner once resin has cured. Allow cleaner to fully evaporate before application of new resin.

Metal Flashing:

Metal flashings shall be fabricated in accordance with the current recommendations of SMACNA and in accordance with standard drawings and project details.

Metal flashing flanges to which membrane is to be bonded shall be a minimum of four (4) inches in width, and secured to the substrate six inches (152 mm) on center staggered with fasteners appropriate to the substrate type. The flanges shall be provided with a roughened surface that has been cleaned of all oil and other residue.

Metal edges that will be overlaid with membrane shall be provided with a 1/4 inch (6 mm) minimum hemmed edge.

Apply primer, resin and fleece to metal flange, extending membrane to outside face of metal edging, and to vertical face of metal base/curb flashing.

Membrane Flashing:

Membrane flashings shall be fabricated with primer appropriate for the substrate surface, resin of the same base chemical type as the field membrane, and fleece of the same weight as the field membrane unless specified otherwise.

Primer, resin, and fleece mixing and application methods as specified for field membranes are also suitable for membrane flashing.

Fleece shall overlap 2 inches (51 mm) minimum for all joints. Fleece shall be cut neatly to fit all flashing conditions without a buildup of multiple fleece layers. Work wet membrane with a brush or roller to eliminate blisters, openings, or lifting at corners, junctions, and transitions.

Pipes, Conduits, and Unusually Shaped Penetrations:

Flash all penetrations using cold fluid-applied reinforced (PMMA) methyl-methacrylate waterproofing membrane. Flashing material shall be the same resin used in the field membrane with fleece reinforcement.

Flashing is typically constructed as a two part assembly consisting of a vertical wrap and a horizontal target patch. There shall be a minimum of a two inches (51 mm) overlap between vertical and horizontal flashing components.

Drains and Scuppers:

Acceptable drain and scupper materials are cast iron, cast aluminum, and copper.

Connect new drains and scuppers to existing storm sewer system.

Alternatively, replace all broken or damaged parts of existing drains and scuppers, or provide and install an acceptable insert.

Flash drains and scuppers using cold fluid-applied reinforced (PMMA) methyl-methacrylate waterproofing membrane. Flashing material shall be the same resin used in the field membrane with fleece reinforcement.

Flashing material shall extend four inches (102 mm) minimum onto drain, scupper, or insert flange.

Install clamping ring if provided as part of the drain or scupper design. Install a strainer basket to prevent debris from clogging the drainage line.

Hot Stacks:

Protect the membrane components from direct contact with steam or heat sources when the in-service temperature exceeds 150 degrees F (66 degrees C). In all such cases flash to an intermediate "cool" sleeve.

Fabricate "cool" sleeve in the form of a metal cone using galvanized metal in accordance with Membrane manufacturer's details.

Flexible Penetrations:

Provide a weather tight gooseneck of round cross-section for each penetration or group of penetrations. Set in water cut-off mastic and secure to the structural substrate.

Acceptable gooseneck material is copper, of a sheet weight appropriate for the application.

Walls, Curbs and Base Flashings:

Wall, curb and base flashings shall be installed to solid substrate surfaces only. Adhering to gypsum-based panels, cementitious stucco, synthetic stucco, wood or metal siding, and other similar materials is not acceptable.

Flash all walls, curbs and base flashings using cold fluid-applied reinforced (PMMA) methyl-methacrylate waterproofing membrane. Flashing material shall be the same resin used in the field membrane with fleece reinforcement.

Reinforce all transition locations and other potential wear areas with a four inches (102 mm) wide polyester fleece bottom layer evenly positioned over the transition prior to installing the exposed flashing layer.

Reinforce all inside and outside corners with a four inches (102 mm) diameter conical piece of fleece prior to installing the exposed flashing layer.

All pins, dowels and other fixation elements shall be flashed separately with a vertical flashing component prior to installing the exposed flashing layer.

Extend flashing a minimum of four inches (102 mm) onto the field substrate surface.

Drip Edges and Gravel Stops:

Metal drip edges and gravel stops shall be installed to solid substrate surfaces only. Securement to gypsum-based panels, cementitious stucco, synthetic stucco, wood or metal siding or coping, and other similar materials are not acceptable.

Flash all drip edges and gravel stops by extending the field membrane all the way to the edge of the exposed face prior to installing the metal edging. Strip in the metal flange with a separate 8 inches (203 mm) wide strip of membrane adhered to both the securement flange and to the field membrane.

For conditions where water infiltration behind the exposed drip edge or gravel stop face is possible, install a separate polyester fleece bottom layer positioned behind the face area and extending a minimum of four inches (102 mm) past the securement flange onto the field substrate prior to installing the drip edge or gravel stop.

Field Fabricated Control or Expansion Joint Flashing:

Control or expansion joints in excess of two inches (51 mm) in width require the use of a separate engineered joint system.

Control or expansion joints two inches (51 mm) or less in width may be flashed with two layers of cold fluid-applied (PM MA) methyl- methacrylate waterproofing membrane and a compressible foam or rubber insert. Use polyester reinforcing fleece bottom and top layer.

Grind or otherwise bevel the inside edges of the joint opening to provide a smooth transition edge for the fleece.

Flashing typically consists of polyester reinforcing fleece bottom layer looped into the joint as a cradle, a compressible foam or rubber insert at 25% compression fitted into the joint, and a polyester fleece top layer applied over the joint. Extend both fleece layers four inches (102 mm) minimum onto the field substrate on both sides of the joint.

Apply the field membrane over the entire joint area.

Electrical Conduit, Gas Lines and Lightning Protection:

Supports for electrical conduit and gas lines greater than one inch (25 mm) in diameter require the use of a separate engineered support system.

Supports for electrical conduit and gas lines one inch (25 mm) or less in diameter, and bases for lightning protection rods and cable, can be adhered directly to the membrane surface with two-component Alsan RS Paste or a single-component, high quality polyurethane sealant supplied by membrane manufacturer.

LIQUID MEMBRANE APPLICATION

General:

Mix and apply cold fluid-applied reinforced (PMMA) methyl-methacrylate waterproofing membrane in strict accordance with written instructions of Membrane Manufacturer. Use only proprietary membrane resins and materials, as supplied by the membrane manufacturer.

The primed substrate surface shall be dry, with any remaining dust or loose particles removed using clean, dry, oil-free compressed air, industrial vacuum, cloth-wipe or a combination.

Two-part (PMMA) methyl-methacrylate resins cure most quickly and completely when exposed to UV light. For concealed and/or interior applications where exposure to natural UV light cannot be obtained, exposure to a UV light source or a supplemental source of hot air blown over the membrane surface will improve membrane cure.

Protect all areas where membrane has been installed. Do not work off installed membrane during application of remaining work before three hours of curing. Movement of materials and equipment across installed membrane is not acceptable. If movement is necessary, provide complete protection of affected areas.

Closely follow the Membrane Manufacturer's recommendation for hot and cold weather application. Monitor surface and ambient temperatures, including the effects of wind chill.

Mixing of Resin:

Mix resin with a spiral agitator for a minimum of 2 minutes until the liquid has a uniform color.

Add the pre-measured Catalyst Powder to resin and mix with the same agitator for 2 minutes or until the powder is completely mixed. The catalyst is completely dissolved when there are no white specs remaining.

Application of Resin/Fleece:

Roll out dry polyester fleece onto the liquid resin mix, making sure the SMOOTH SIDE IS FACING UP (natural unrolling procedure), avoiding any folds and wrinkles. The fleece will begin to rapidly saturate with the liquid resin mix. Use a medium nap roller or brush to work the resin into the fleece, saturating from the bottom up, and eliminating air bubbles, wrinkles, etc. The appearance of the saturated fleece shall be light opaque amber with no white spots. White spots are indications of unsaturated fleece or lack of adhesion. It is important to correct these faults before the resin cures.

Prevent contact between mixed/unmixed resin and new/existing membrane. If any unmixed resin contacts membrane surface remove immediately and clean thoroughly with a cloth rag.

At all fleece seams, allow a 2 inches (51 mm) overlap for all side joints and a 4 inches (102 mm) overlap for all end joints.

At membrane tie-offs, clean in-place membrane with Alsan RS Cleaner once resin has cured. Allow cleaner to fully evaporate before application of new resin.

Alsan RS 230 Field resin is alkalinity resistant. Additional bond/wearing layer consisting of one application of Alsan RS 230 Field on horizontal surfaces and one application of approved broadcast mineral aggregate surfacing shall be applied wherever stone, concrete, or masonry elements will be placed directly over the flashing.

PRIMER APPLICATION

Priming is not normally required on clean SBS modified bitumen, smooth BUR and most metals.

Apply Alsan H80 prime at 5 to 6 wet mils (0.13 to 0.16 mm). Amount of primer needed is affected by surface roughness and porosity. The primer when applied shall have a glossy appearance. Use of H80 will promote better adhesion and can help reduce the amount of base coat needed.

Any aged roof, after substrate preparation, will require priming particularly where ponded water or residual dirt has been present.

Primers shall be allowed to dry for 6 to 12 hours depending on environmental conditions prior to the Alsan Flashing Application. Primed substrates may only be exposed for a period of 24 hours prior to the application of Alsan Flashing or they shall be re primed.

** NOTE TO SPECIFIER ** Urethane System. Delete if not required.

3.11

FLASHING APPLICATION

For all flashings, penetrations, drains, metal edges, etc. apply an even base fleece coat of Alsan Flashing resin with a brush or roller. Embed Alsan PolyFleece in this layer and immediately apply a top fleece coat of Alsan Flashing wet-on-wet. Cut Alsan PolyFleece 4 inches (102 mm) wider than the split, seam or transition in each direction. Ensure that polyester reinforcement is fully saturated and does not have voids, fish mouths, trapped air, or wrinkles. To the cured base coat apply an Alsan Flashing finish coat. Broadcast to excess ceramic granules into the finish coat. As an option in place of the granules, allow the finish coat of Alsan Flashing to cure 9-12 hours and then apply a coat of colored Alsan 310.

Base Fleece Coat: Minimum consumption of 32 wet mils (0.81 mm) depending on surface texture.

Top Fleece Coat: Minimum consumption of 32 wet mils (0.81 mm) depending on surface Texture

Finish Coat: Minimum consumption of 32 wet mils (0.81 mm) depending on surface texture.
