The Nature of Rubber

Rubber comes in many forms. From footwear to car tires to hoses and floor mats – rubber is an extremely versatile material. This is because it is easy to form into different shapes and it is very tough. Rubber can be extruded, injection-molded, or rolled into sheets. Rubber is a broad term. There are two main variants of rubber. Natural and synthetic rubber. Before we take a look at how to paint rubber and the best paints for painting rubber, let us take a deep dive into the world of rubber!

Origins

Rubber can be traced back to around 1000 B.C.E. when central and southern Americans used this type of rubber daily. It was harvested from rubber trees and used to make waterproof clothing and tools. In the early 1800s, a French explorer by the name of Charles Marie de la Condamine sent a sample back to Europe which stirred up a lot of interest. Thereafter there were many developments of this raw material and with it, a proliferation of products followed suit.

Traditional Thai Rubber Production

In 1910 a Russian scientist named Sergei Vasiljevic Lebedev developed the first synthetic rubber. From then on, rubber production grew in popularity as synthetic rubber became much cheaper than natural rubber. Today one of the largest consumers of rubber is that of car tire manufacturing!

 

Natural Rubber

Natural rubber comes from a South American indigenous tree. A milky sap-like liquid of this tree can be tapped from cuts in the tree’s trunk. When it dies, it forms natural latex rubber. Trees can be tapped often and can yield about a cup of latex rubber every two days.

Tapping a Rubber Tree

The latex rubber is processed and compacted into brick and shipped. Sometimes the rubber rolled into sheets and smoked to prevent mold growth. This smoke contains natural fungicides. Natural rubber is used to make a wide range of products such as surgical gloves, pacifiers, children’s toys, and car tires!

 

Synthetic Rubber

Synthetic rubber is made from crude oil and comes in many different forms. The type of rubber is defined by chemical manufacturing processes. The most common types of rubber are butyl, acrylic, ethylene-propylene, styrene-butadiene, and silicone rubbers. Each of these has its pros and cons.

Modern Rubber Production

Over 30 million tons of both synthetic and natural rubber are produced every year in the U.S.A. More than two-thirds of this is synthetic. Thankfully, rubber is recyclable. Choosing to reuse and upcycle old rubber products is a great way to reduce waste!

Properties

Rubber can have many different properties depending on how it is manufactured and what additives are used. Rubber can be resistant to extreme temperatures, abrasion-resistant as well as chemical and oil resistant. It is very tough and can be very stretchy! Rubber can be as hard as wood or soft as a kitchen sponge. It is the wide array of properties that make rubber incredibly versatile.

Rubber Pacifier

It is important to note that while you can paint rubber, painting very flexible rubber such as a swimming cap or latex gloves will not work well at all. However, choosing to paint hard rubber like a car tire or shoe soles is possible. Read on to learn more about what the ideal paints are for rubber!

How to Paint Rubber Tires

Upcycling car tires is a great way to reduce waste! Car tires make great garden swings and planters. Painting old rubber tires is a wonderful way to liven things up! Rubber tires are not very flexible which makes them ideal for painting. You will need to select high-quality exterior paint for painting rubber tires. And it is always a good idea to apply a primer before applying the paint.

Cleaning the Tires

Be sure that the tires are free from dirt, grease, and grime. Warm soapy water should help you to remove most impurities from the surface. If you are looking for a more extreme clean you can try some trisodium phosphate (TSP) soap. Use a coarse bristle brush to get into cracks and tread. If you are planning to cut or drill holes in the tires you will want to get this out of the way first. Take care when cutting rubber. Blades can get stuck in the rubber so it is best to use dish soap as a lubricant.

Clean Rubber Tires Before Painting

 

Priming and Painting

To increase the adhesion of the primer and the paint you can use coarse grit sandpaper to roughen the surface of the tire. This will create a surface profile that the primer can bite into. A tack cloth will remove any grit or dust. Your tire should be completely dry before you apply the primer. Primer will further increase the adhesion of the paint. Applying with a brush, roller, or sprayer. A sprayer will help you to cover tricky areas like tread patterns and cracks.

Let the primer dry before applying your paint. The drying time will vary between manufacturers. When the primer is dry you can begin painting the tires in the same way that you did with the primer. If you are painting a light color onto tires, you have a difficult time covering up the black. This may require multiple coats of paint.

Take your time and allow each coat of paint to dry before applying the next. Once you have completed painting you will need to allow for the paint to cure before use. Read the information on the packaging of the paint to find out the drying times. Bear in mind that these times will be affected by the weather and overall climate. Applying a clear polyurethane sealer to the painted tires will make your coating even more durable!

Uses for Painted Rubber

 

 

How to Spray Paint Rubber Boots

Rubber boots are a very practical choice in footwear, especially in wet weather! You may be considering adding a splash of color to an old pair that you have lying about. This is a fun project and very easy to do! To get the job done fast you should opt for spray paint with a built-in primer. This type of paint will offer a decent bond to the rubber boot and offer a good level of flexibility too!

Clean and Prep the Rubber Boots

Clean the rubber boots before doing anything. Any dirt or oil will prevent the adhesion of the paint. Use soapy water and a coarse bristle brush to scrub your rubber boots and allow them to dry. Use coarse-grit sandpaper to scuff the surface of the rubber and remove the gloss. This will ensure your paint bonds to the rubber.

Clean Rubber Before Painting

Use a tack cloth to strip the surface of any grit and dust. If you are planning to paint the uppers only, you may want to cover up the sole with painter’s tape. This will prevent annoying overspray. Cover any areas that you do not wish to paint with painter’s tape.

 

Spray Painting Rubber Boots

Shake your spray can until the metal agitator is moving freely within the can. You should continue to shake the can for 2 to 3 minutes. This will ensure that the spray paint and propellant have been mixed sufficiently. Stand your rubber boots a few feet apart on some old newspaper, preferably outdoors. If you are forced to work indoors you should wear a respirator and open all the doors and windows.

Painting Rubber Footwear

Hold the can about 8 inches from the surface of your rubber boot and spray in short controlled bursts while moving the can in short controlled strokes. This will prevent any drips from forming. It is better to apply multiple thin coats than a single thick coat. This will create a more professional look and even finish. Wait for the previous coat of paint to dry before applying the next. Drying time will be mentioned on the spray can.

Tips and Tricks

  • Before painting rubber, be sure that the rubber is clean and free from any oils or dirt. Soap and water should do the trick. The rubber should be completely dry before applying your paint.
  • When painting firm rubber-like a car tire, use sandpaper to roughen up the surface and remove any gloss from the tire. This will improve the bond of the paint to the tire. And remember applying a primer first is always a good idea!
  • Using spray paint on rubber is a great way to speed up the process. However, selecting the correct paint will make or break your project. For best results, choose a high-quality spray paint that contains a primer.
  • If you are planning to paint car tires it is best to do any cutting and drilling beforehand. Choosing to cut and drill after the fact may lead to damaging your new coat of paint. When cutting a tough car tire try lubricating the blade with dish soap to help it glide freely.
  • When painting on rubber use painter’s tape to hide any surfaces that you do not wish to paint. You can also create interesting patterns on rubber tires using painter’s tape. Simply lay down the painter’s tape in an interesting pattern. Spray over the design. Allow the paint to dry, remove the painter’s tape. Voilà!

 

 

Painting rubber is easy! However, selecting the correct paint is important. It is best to select flexible paint for rubber. Bear in mind that painting super flexible rubber such as a swimming cap will not work. The paint will simply crack and peel off when the material is stretched. That being said, painting firm rubber-like car tires or rubber footwear is possible! Apply a primer before applying an exterior paint or for a more convenient option use spray paint with a built-in primer. For the most durable coating on rubber try marine paint!
