Epoxy Resin Coating Explained And Cost Overview

Epoxy Resin Coating Explained And Cost Overview

Epoxy resin is the material of choice when it comes to creating durable and waterproof surfaces. It is excellent for sealing porous and organic materials. In addition, epoxy resin can be used in conjunction with glass fiber mats to produce all kinds of free forms. In fact, this material, also known as “two-component adhesive”, plays a crucial role in prototype construction and in wind power. Find out in this guide what you need to look out for when processing epoxy resin and what the costs are.

Durable material with good-natured properties

Epoxy resin, 2K resins or two-component adhesives have been in private and universal use for many years. It consists of the two components “resin” and “hardener”. Both materials are relatively viscous masses that become more fluid when heated. Unmixed, they remain in their usual liquid consistency for a long time. However, as soon as they are mixed together, a chemical reaction begins. This creates a solid mass that no longer deforms, even under temperature and mechanical stress.

Demanding in processing and disposal

As practical as the properties of epoxy resin are, this material is very demanding when it comes to processing and disposal. In the intended place, epoxy resin can deliver great results. Until then, however, a lot can go wrong. This applies above all to its preparation: the respective mixing ratio must be adhered to exactly, otherwise the material acquires undesirable properties. This can result in anything from a sticky surface to clouding and cracking.

Occupational safety is also important when handling epoxy resin. Once mixed, epoxy resin consistently sticks together everything it comes in contact with. When mixing and applying epoxy resin, at least eye protection must be worn. In the event of contact with the eyes, the eye must be rinsed under clear water for at least 15 minutes and then a doctor must be consulted! Skin contact should also be avoided. That is why wearing full-body suits when handling epoxy resin is mandatory. Paper protective suits, for example, are suitable for this. You should avoid high-speed drills when mixing epoxy resin. Otherwise, there is too much danger of the material spilling over or splashing around.

Overview of the resins

Epoxy resin is not just epoxy resin. The trade offers a selection of resins, with which the right agent is available for the respective project. In addition to the epoxy resins, we also list their related polyester resins here.

As with many building materials, the price depends on the container size. A one-kilogram can is particularly uneconomical. From 5 kilograms, the price is already halved for most products and only decreases a little from this mark. Therefore, try to always use 5 kilograms or more. Form a team with friends for joint projects. This way you can save a lot of money.

The trade offers epoxy resin in a combination package of resin and hardener. You can also buy resins and hardeners separately. However, we recommend always choosing the combination packages. This gives you the certainty that you have always bought products that perfectly match each other.

This overview should give you an orientation for the prices. We have oriented ourselves to the products of the well-known brand “Resinpal”. The main difference between polyester resin and epoxy resin is the amount of hardener required. With polyester resin, only a few grams are needed. However, epoxy resin consists of up to 25% of the mass of the hardener. This must be taken into account when calculating the required quantities.

More than just clear coating

Today, the industry offers epoxy resin-based solutions especially for floor coatings that promise fascinating results. We are talking about colored or flocked floors and stone carpets. This solution is ideal if a used tile, concrete or wooden floor needs to be freshened up before a total renovation. The processing is quite quick and easy. However, it is not cheap. For a stone carpet you have to reckon with 35-70 euros per square meter. In the meantime, many homeowners have recognized the qualities of stone carpets and are already choosing this solution for new buildings. Another advantage is that they are easy to repair.

These synthetic resin floor coating solutions consist of a regular 2K resin mixed with fillers and colorants. In the case of pure color coatings, the color is already mixed in with the resin and in the container. Flocking or suitable stones are added by the user himself.

Manufacturers offer a huge selection of different designs and materials. When it comes to stone carpets, the usual range is marble, glass and quartz. These three basic materials are available in an enormous selection of colours, which can also be individually adapted by cleverly mixing them.

Processing of epoxy resin

There are various applications in which an epoxy resin floor coating is used. Concrete seals, leveling compounds, clear seals or design coatings are common. Using the example of a concrete seal, we would like to explain how to use epoxy resin. This basic sealing is also well suited as a structure for a further coating of epoxy resin.

To make an epoxy resin floor coating you will need:

  • Protective clothing for complete skin protection
  • face shield
  • powerful cordless screwdriver or with precisely controllable rotational speed
  • stirrer
  • possibly flat spade
  • vacuum cleaner
  • Masking tape for masking
  • paint brush
  • small and large paint roller with low pile (max. 4 millimeters)
  • thinner

First, the floor is thoroughly cleaned. If the unfinished floor still has cement noses, you can knock them off with a flat spade. The room is then thoroughly vacuumed and wiped. If necessary, then tape the walls and fixtures in the room (e.g. door frames) with masking tape. Now stir the mixture in a clean bucket, ideally a new one. After mixing, add 1/3 thinner. Then let the mixture mature for about 15 minutes. You can now easily distribute the very liquid mass with a brush and roller. Work now to cover, that means crosswise. Let the base coat set overnight. Now mix up a second mixture. This time she stays undiluted. Apply the coating again with the roller. Work in a criss-cross pattern again, making sure

Clear coat is not brushed on, but spilled over the floor directly from the mixing bucket. Proceed in an S-shape to achieve even discharge. Help spread with a squeegee. The runny mass will mostly even itself out once the ground is completely covered. Back up to the door and use the squeegee to smooth out any footprints. Let the mixture harden completely, making sure that nobody enters the room. This is how you get a good result.

Tips for speed readers

  • Find out exactly which epoxy resin you need
  • Work clean and tidy. Epoxy resin is unforgiving.
  • Pay attention to occupational safety, especially for the face and eyes
  • Always mix exactly according to the mixing ratio. Epoxy resin is a demanding material.
