Product Information:

Liquid Rubber offers a range of products to coat and waterproof your Mod-Bit / Torch Down roof. Our products are designed to extend the life of your roof by approximately 10 years. They provide exceptional flexibility, elongation, UV protection, and come in various colors. Whether you need to repair or protect your Mod-Bit/ Torch Down roof, Liquid Rubber has a solution for you.

Preparation:

Inspection:
Prior to starting the work, it is important to perform a thorough inspection of the roof. This includes checking for proper drainage and ensuring the integrity of the coating. Additionally, a moisture test should be conducted to determine if the insulation is saturated. Moisture can lead to blistering, while inadequate drainage can cause issues with the substrate and result in ponding.

Regular inspections should be performed to identify and address small problems before they become bigger issues. It is recommended to apply Liquid Rubber Roof Coatings as a preventative measure before any leaks occur. This proactive maintenance can save you the cost of repairing water-damaged interiors and electrical/mechanical components.

General Preparation & Cleaning:
Prior to applying Liquid Rubber products, the surface must be clean, dry, and structurally sound. It should be free of sharp edges, efflorescence, laitance, dirt, debris, oil, grease, coal tar, mastics, flaking paint, silicone, other coatings, orcontaminants.

To achieve a clean bonding surface, you can use compressed air, a sweeper, or a pressure washer. If necessary, a degreaser can be used. However, caution should be exercised when introducing water, as the surface must be completely dry for proper application and curing. It is recommended to remove any prior coating to ensure optimal adhesion. Conduct a test to confirm adhesion before applying over an existing coating.

For hidden moisture detection, it is advisable to scan the roof using an infrared scanner or an equivalent method. If the roof is not completely dry at the time of application, any remaining water can evaporate and lead to pinholes, blisters, and delamination of the coating.

Product Usage Instructions

Detail Work:
Detail areas such as vents, skylights, chimneys, etc., require special attention. For these areas, follow the steps below:

Pre-cut Liquid Rubber Seam Tape to the desired length and fit.
Remove the plastic backing from the Seam Tape (be careful not to stretch it when removing the backing).
Apply the Seam Tape to all seams at the perimeter and protrusions (vents, skylights, etc.).
Use pressure to activate the adhesive, ensuring there are no wrinkles or fish-mouths.
If overlapping separate pieces of Seam Tape, make sure to overlap them by at least 1 inch.

Alternatively, Geo-Textile applied via the 3-course-method may be substituted for Seam Tape.

For walls with metal cap flashing, it is recommended to follow these steps:

Remove the cover of the metal cap flashing.
Repair any damage to the parapet wall.
Apply the 3-course-method or Liquid Rubber Seam Tape.
Replace the cap flashing.

PREPARATION

Even the best roofing systems and products begin to break down over time. For a fraction of the cost of re-roofing your mod-bit/torch down roof, you can extend its life (by approximately 10 years) by using Liquid Rubbers’ easy to apply waterproofing solutions.

Inspection:
A thorough inspection of the roof establishing proper drainage prior to beginning work must be performed to ensure adhesion and the integrity of the coating. A moisture test should be performed to determine if the insulation is saturated. Moisture will result in blistering and inadequate drainage can result in unforeseen issues with the substrate and create unnecessary ponding.
Inspections should be performed regularly to identify small problems before they become big problems. It is best to apply Liquid Rubber Roof Coatings before you have a leak. This kind of preventative maintenance can save you the cost of repairs involved in water damaged interiors and electrical/mechanical components.

General Preparation & Cleaning

(Prep is 90% of the job!)
Liquid Rubber products must be applied to a clean, dry, and structurally sound surface that is free of sharp edges, efflorescence, laitance, dirt, debris, oil, grease, coal tar, mastics, flaking paint, silicone, other coatings, or contaminants.
Clean using compressed air, a sweeper, or pressure washer, and/or degreaser if necessary to provide a clean bonding surface. (be cautious when introducing water, as the surface must be completely dry for application and cure). It is always best to remove any prior coating or adhesion may be limited to the underlying coating and could delaminate. It is best to do a test to confirm adhesion before application over an existing coating
Scan your roof using an infrared scanner (or equivalent method) to detect hidden moisture. If the roof is not completely dry at the time of application, this water can evaporate and may cause pinholes, blisters, and delamination of your coating.

DETAIL WORK

Detail areas may include vents, skylights, chimneys etc. Pre-cut Liquid Rubber Seam Tape to desired length and fit. Remove plastic backing before applying (be careful not to stretch the seam tape when removing the backing). Apply Seam Tape to all seams at perimeter and protrusions (vents, skylights, etc. )
Use pressure to activate adhesive leaving no wrinkles or fish-mouths. Overlap separate pieces of Seam Tape by at least 1 inch. Geo-Textile applied via the 3 -course-method may be substituted for Seam Tape.
For walls with metal cap flashing, it is recommended to remove the cover, repair any damage to the parapet wall, apply 3 course-method or Liquid Rubber Seam Tape and replace the cap flashing.
(Remember, these are the area’s most likely to leak so pay special attention to the details, nobody wants to do it twice!)

APPLICATION

Termination:
Tape-off, block off or otherwise mark areas that are not to receive coating. TIP: Pull your masking tape while the coating is still wet. You may re-tape or stay shy of the termination line on your following applications. If you allow your coating to dry too much, you can score/cut along the tape line before pulling to prevent the chance of lifting the coating.

Application:
Once your preparation is completed, clean and dry, begin your full field application. Begin in the farthest corner and work toward your exit. Work in manageable sections (i.e. 10 ft x 10 ft) and inspect as you go. Lap onto adjoining sections while applying to the new section. Talk to your Liquid Rubber Technical Rep to determine which product is best suited to your application.

Final Inspection:
After the final coating has dried sufficiently enough to walk on and not cause damage, inspect the area for uniformity of membrane thickness and coverage. Inspect for pinholes, blisters, voids, thin spots or other defects. Repair as necessary.

APPLICATION TIPS

Be sure to consult local building codes prior to application.
Apply using a 3/8 (10mm) roller, brush or heavy duty airless paint sprayer.
Ensure drains are present and functioning correctly.
Apply to dry surface that is free of dirt, loose paint, rust, oil, grease, coal tar, silicone, or other contaminants.
Apply when temperature is above 10°C (50°F) and rising. (Including overnight temps)
Apply final coat in the direction of slope for positive drainage.
Apply next coat when dry to the touch with nothing wet underneath and is uniform in color.
Avoid hot, direct, intense sun when applying.
Avoid contact with solvents and solvent based cleaners, adhesives, and paints.
Do not allow to freeze until fully cured.
For the Silicone Roof Coating A bleed blocking primer is needed for bitumen based systems to prevent bleed through – A TPO primer is needed to increase adhesion on TPO surfaces – Contact Technical Support
Not meant for walking surfaces.
Seal gaps, cracks, etc. with Liquid Rubber Sealant & Adhesive (or equivalent).
Initial cure(set) within 48 hours or until completely dry.
Make sure what you’re coating is at least 5 degrees above the dew point of the environment you are coating in. (See technical specs for more details)
For best results remove existing paints/coatings and apply directly to the substrate. (Some paints and coatings will not be compatible. Loose/flaky paint may be an indication that the existing paint/coating is not well bonded and therefore your Liquid Rubber solution may fail if applied over it instead of directly to the substrate. Oil based paints, enamels, epoxies, powder coats can be difficult to bond to. Contact your Liquid Rubber technical representative for further direction.)

CLEAN UP

It turns out that cleaning up your mess is not nearly as fun as making one, so follow these rules.

Always organize yourself and your work area to reduce the potential for spillage and other accidents.
Set out a tarp or large piece of cardboard to keep containers and tools on, when not in use.
Soak up as much material as possible with rags.
If dried, scrape off as much as you can, (with a razor/scraper/etc.) then scrub with a brush/wire brush, etc.
Colored Products: Clean with soap and water.
Bitumen or Silicone: Clean immediately with mineral oil/ baby oil for hands and use odorless mineral spirits for surfaces to weaken the material and an appropriate tool to mechanically remove (wire brush, grinder, etc.)
(test odorless mineral spirits in an inconspicuous area first to ensure no discoloration)
If dried, scrape off as much as you can. (with a razor/scraper/etc.)
Warning: Mineral spirits can spread the stain, be sure to use sparingly, in a controlled manner, and to follow the manufacturers safety recommendations.
Refer to the Product Safety Data Sheet for personal protective equipment recommendations.
