This article describes the pros and negatives of applying different types of difficult coatings around foam resources, including epoxy, Polyurea, Memory and Rubber-Latex. It describes the big difference between each difficult covering selection, and how to determine when to use either one

Posts rain, snow, humidity, moisture and sunshine that could otherwise degrade the surface, and is intended to offer a defensive layer allowing the merchandise to last longer.



There are many different difficult covering products out there. For our applications, we like to use Epoxy covering, Polyurea covering, Rubber-Latex covering and Memory covering (both delicate and hard).

So what is the big difference between each one of these? What are the pros and negatives of every and how do we choose when to use either one?



We use Epoxy difficult covering for any foam item we fabricate where the customer takes a slim protective layer / if the merchandise needs to be placed external for a limited length of time (up to 2 month for ex) / for foam products that must be put into water such as pool letters. The epoxy, readily available, offers a bright glossy look and a relatively easy end look. It will protect for a limited time but mightn't last a life-time since it's thin. Some need sanding and patching following covering and ahead of painting for a simpler structure finish.,

The epoxy is applied by brushing or rolling it on the foam. Generally 1-2 coats can do the trick, often a 3rd coat is required for extra protection. We let it dry absolutely for up to twenty four hours (it solutions at space temperature, most useful at around 75F degrees, but can remedy between 60F-90F as well) , then we sand or leading or color with acrylic paint.

It is a two part program with a glue to hardener combine ratio.

The epoxy is ideal for guarding signs, logos, words, props, architectural facades and precast molds. The problem of applying epoxy is that upon influence it could crack or break, but it is an economical solution.



For a  heavier, tougher covering, we change to the Polyurea product (also referred to as Bed Liner). That is correct if the task will be placed outside for a lengthy period of time, if people can touch it, or if it needs to last a life-time. It might be applied as an alternative for fiberglass covering, because it is resilient, strong. And water limited

The Polyurea is more costly than the epoxy and is a more complicated software process. It is frequently dispersed on utilizing a plural aspect sprayer system. For this method, you must have excellent knowledge and teaching applying the product to be done correctly and it needs to be sanded ahead of priming and painting. After software, the sprayer needs to be cleaned well otherwise particles may clog it and it wouldn't perform, not letting the covering product flow out for next use.

The Polyurea product solutions rapidly in a matter of seconds and is difficult to the touch however continues flexible throughout their life. There are many flavors of Polyurea - Which range from very hard like plastic and brittle to rubber-like. It is a superb solution for treating big materials (we even spray airline hangers with it and other floorings), it's water-resistant and also comes in a fire retardant option. 

The drawback is that the product and process are costly, as well as it takes continuous equipment maintenance.

Polyurea could be dispersed on any product which range from foam, parts, cardboard, wood, concrete, and metals.

There are subcategories of the polyurea, such as StyroSpray1000. It defines a leaner coat that is dispersed, blown or rolled on. It is a cheaper process, however it could be more leaking and involves more sanding and is most effective at damp environments.



Yet another protective layer we use is Memory coating. It is good for industrial, art-related and amateur tasks, and can be acquired as firm or semi-rigid resins. One kind of urethane covering we like to use may be the Rubber-Latex coating.

In cases when you want to give a flexible, however difficult, powerful and influence tolerant covering, we make use of a rubber-latex covering end by brushing it onto the surface. It is actually a flexible kind of covering (creates an atmosphere of nearly a squashy bounce ball). It securities perfectly onto different types of resources, such as EPS foam, cloth, materials, parts and wood. This covering offers floor security, flexibility and weight to UV, abrasion and chemicals. It units nearly straight away, but solutions in a matter of hours (sometimes taking as much as twenty four hours to fully cure) and can not polyurea
be sanded.



There are many other types of coatings out there, such as solution coat, fiberglass, plasters, concrete and more. The type of difficult covering we go for is dependent upon the product and structure to be painted, the design itself (if it's lines and indentations that the covering resources needs to flow into), the conclusion required (smooth vs semi-smooth) and the customer's budget and turn around needs for the project.
