AUTOMOTIVE LIQUID RUBBER COATING

Searching for a quality liquid rubber that delivers beyond your expectations and let you have your automotive in a color of your design? Well, our All-Purpose Liquid does just that for you.

Not sure how all-purpose liquid works? We have an easy DIY product that will you a durable coating without any hassle. Apply All-purpose Liquid Rubber may be applied with ease using either manual or spray application methods. By manual application we mean using conventional brush or roller equipment, or alternately the product may be sprayed using a delivery system and nozzles appropriate for the viscosity of this material.

Achieve the best results from our All-Purpose liquid rubber by following these simple tips and recommendations.

• Coating thickness between 10-20 mils would do your job.
• Apply to a dry surface that is free of dirt, debris, oil and grease.
• Application immediately before the onset of rain is not recommended.

Give your automotive a unique and durable color with our sophisticated designed All-Purpose Rubber Liquid that with its ease of use, promise of quality and consistency of performance is truly a next-generation product.

Proper Preparation Prevents Poor Performance

GENREAL SURFACE PREPARATION:

All materials:

Surfaces must be dry and free of anything that could adversely affect the adhesion of the Dura-Rubber to the surface. You should be sure to remove all loose, scaling, peeling, blistering, chipping, cracking, chalking or gravel, dust, dirt, sand, soot, grease, oil, uncured tar, wax, soap film, animal fats or petroleum-based residue, coal tar, chlorine, salts, efflorescence, or any other chemically reactive substance; and the surface to be coated must be completely free of all mold, mildew or any other living organism and COMPLETELY DRY.

Pressure wash to thoroughly clean all surfaces prior to application when any of the above conditions exist. And the use of an appropriate detergent cleaner. Mildew and similar growths need to be killed with 5% chlorine solution household bleach in water, followed by a thorough rinse with clean water. Do not over pressure wash the bare concrete as you can drive water into the concrete and it will take longer to dry.

All surfaces must then be allowed to THOROUGHLY DRY before proceeding with the application. We recommend doing an adhesion test before final application After all, surfaces are thoroughly dry inspect for cracks, holes and any surface irregularities that will need to be repaired prior to Spray, or roller/brush Dura-Rubber.

If going directly over surface (No other coating on it) make sure the it is completely dry. If the concrete is damp to the touch it is not dry. (Use a fan to move the moisture)

Surfaces must be dry and free of anything that could adversely affect the adhesion to the surface. If going over other products such as epoxy it will need to be etched or roughed up with a grinder or sandpaper so Dura-Rubber can bond properly.

IN ADDITION TO ABUVE:

Concrete:

Concrete by nature is not only a very porous product but also has a tendency to retain moisture for a long period of time. Although it may look dry on the surface there actually is a lot of moisture still inside. Moisture content depends on the relative humidity. Cure time will depend on water-cement ratio. A simple test take an 18-inch by 18-inch clear plastic sheet and put it over the concrete and seal it on all four sides. After 16 hours, if any moisture or darkening of the concrete surface is found, the concrete is too wet for coating. Make sure the sheet does not come in contact with direct sunlight. You can also use a moisture meter. Keep in mind that moisture meters measure the top inch and concrete dries from the top down moisture levels need to be less than 7%.

Metal:

We recommend to clean with a good degreaser rinse well when dry wipe down with acetone before application. On new metal be sure to remove oil from manufacturing.

Epoxies:

If very smooth rough up with grinder or sandpaper. Clean with acetone before application.

TPO:

Clean with acetone before application.

Applying reinforcement fabric if required

Repairing cracks in concrete or other mediums (up to "1/16 cracks or gaps) Repairs should be made with an application of embedded reinforcement fabric, fabric needs to be at least 4" in width, with 2" each direction from repair at all open joints, seams, cracks, holes, or areas of damage as well as at all penetrations, inside or outside corners and at any pan, or threshold that are determined by specification to be part of the waterproof envelope. Apply one thick coat of Dura-Rubber embed fabric in coating and apply one thick coat on top while the base coat is still wet. (like doing drywall tape) see photos below.

Application on new wood, concrete, or ferrous metals should follow the same guidelines as repairs with all seams, joints, imperfections, or penetrations, inside or outside corners, pans, thresholds, or surfaces edges or transitions treated with a coat of , embedded reinforcement cloth and a top-coat of prior to additional coats or final sprayed membrane. This preparation technique will add mil thickness and strength that is in addition to the additional coats or final top-coat - thickness determined by below Application Rate:

Using reinforcement fabric with Dura-Rubber

Application Rate: See application chart above.
Rates of Application are typical:

Its not the number of coats, it is the thickness of the membrane.
If the coverage says to use 5 gallons use all the five gallons.

* These mil thickness recommendations are based on proper application and preparation. Deep Drying / Curing times depend on temperature and relative humidity.

Drying Times: 2-4 Hours
Drying times are typical: See below

Dura-Rubber can be sprayed with an airless sprayer using a .025 or larger spray tip.

Make sure when you apply, all your membrane terminations must be above the water line and dry if no other coating on the concrete.

Do not not thin with water if you need to thin use the propylene glycol extender it will also extend the working time.

"Curing" or "Vulcanization"

You will notice the product is dry to the touch with-in a few hours, and will be waterproof. However, the rubber is still going through a very important process called "Vulcanization" - this is the process where the rubber becomes one single membrane and can contain water on a continuous basis. The process of "Vulcanization" takes 7-10 days. Depending on temperature and humidity SEE BELOW.

A good test is splash some water on the membrane and if it turns white it is not dry if it lightens it is not cured.

You do not want to expose coating to chemicals or continuous water saturation until the vulcanization process is complete. If you have a question about your specific applications please do not hesitate to contact us either via the phone, e-mail or our live online support chat. We are here to help! If the product is not properly cured and you fill with water, you will get little gas bubbles.

Optimal vs. Acceptable Humidity Levels

Optimal relative humidity (RH) levels for exterior applications tend to be in the 40-50% range or lower. Levels of 70% or greater will "drastically slow drying and curing," but again will not prevent you from applying.

Applying above an RH level of 85% is strongly not recommended. The coating will remain gummy and gel-like until the RH lowers to an acceptable level long enough for it to solidify. However, because the coating has not been allowed to "level" properly, the texture will remain wavy and otherwise unacceptable.

Temperatures Work With Humidity, Too. One tip is to time your application so that temperatures are on the rise--several hours before the day's peak temperature, which is usually in the late afternoon. High humidity will slow dry time. You need to build in a head-start by beginning hours before you think it is time to begin: Even though the temperature was OK at the time of application, the coating can stop coalescing. This permits moisture to get into the uncured paint film allowing certain ingredients to come to the surface when the moisture evaporates, causing surface staining and possible adhesion problems.

Remember to check the surface temperature as well.
