What is Epoxy
Epoxy floor coating is a great component that works well in boat building and repair, including fiber boat repair. Its use is not limited to boats, and can be used in general woodworking, even for home repairs, provided that the price is a little salty. You can ask these applications for more curiosity by reaching spectrum foor coating consultants. It is technically called “thermoset plastic” if I do not remember wrong. It consists of two syrup components in separate containers: “resin” and “hardener”.You mix these two in different proportions depending on the manufacturer of the epoxy floor coating system. When you mix it in the proper proportion, an exothermic reaction, which gives off heat, starts and the epoxy gradually hardens. First, the gel (or jelly) stage passes through a given stage, that is, the jelly becomes a consistency, then this jelly gradually becomes hard, becoming stiff.Let’s call it “ice cream” if you want, but while ice cream means real cold, epoxy freezes with heating, but still. Frozen epoxy flooring is an extremely strong adhesive with excellent waterproofing properties. I have read from multiple sources that a well-made plywood-epoxy bond is stronger than plywood. You can work on it until it reaches the epoxy jelly stage. How long it will take will depend on several factors and these will be explained later.Let’s say the mixed resin and hardener are not a thickened (or thin) epoxy floor coating unless other ingredients are added. With thin epoxy, you can insulate your material (plywood and wood for us) against water. It can also be used as an adhesive, but this latter is preferred because a bond of the same strength can be obtained by slightly thickening the spectrum floor coating epoxy. When thickened, both epoxies are used more economically and thin epoxy is difficult to hold at the junction of the syrup consistency. The filler called “Filler” is used in English to thicken the epoxy. Almost every epoxy manufacturer also produces a variety of fillers. Each filling bond strength, color, ease of sanding etc. It has different features in terms of. Usually powder fills are much cheaper than epoxy itself. Therefore, it is a more guaranteed way for amateurs to purchase directly from the epoxy manufacturer, although it is possible to replace other things as fillers. When you pour the resin and hardener into a container and mix well, you get fine epoxy. In this mixture, you add the filling until you get the desired consistency by stirring constantly. According to the thickened epoxy consistency, a terminology is developed.
epoxy floor coating Where and how to use?
Insulation (Coating)
When you want to insulate your board or counterplate against water, you use thin epoxy. A brush can be used for this job, but you need to throw the brush to the end because nothing freezes the epoxy floor coating. So use the cheapest brush you can find. If you are isolating large surfaces such as the body, there are better ways to use a brush. You can pour some epoxy on the surface and spread it with a sponge roller. In my experience, the best way is to pour the spectrum epoxy floor coaiting again and spread it in a smooth semi-hard plastic (squeeze in English) by making circular movements. It is even better if you do this job at a narrow angle between the surface and plastic as much as possible. You minimize the formation of unwanted air bubbles. It is better to sand the surface first, as the epoxy penetrates the surface, your insulation will be better. This process not only allows the epoxy to penetrate better, but also allows you to get rid of foreign substances (such as oil) that may be present on the surface. Of course, you need to clean the sanding powder. Multiple insulation layers are generally recommended for boats.
wetting
Although thin epoxy floor coating can be used directly as an adhesive, it was stated that thickened epoxy is preferred for this work. Just like the insulation, the strength of the bond depends on how much epoxy penetrates the surfaces to be bonded. If thickened epoxy flooring is applied directly to the bonding point, the material will absorb some epoxy from this mixture and your bond will weaken as the amount of epoxy remaining in the mixture will decrease. Therefore, both surfaces must be wetted with fine epoxy before applying thickened epoxy to the bonding point. It is worth remembering this process, since plywood, especially the edges of the plywood absorb a lot of epoxy. The most economical application is to wet the surfaces after preparing them for the epoxy floor coating, then to add a filler to the thin epoxy that remains in the container and to go to the adhesion process. If you do not, be sure to apply the epoxy thickened in the wetted parts without freezing.
Epoxy Fiber fiber application
When applying fiber, you use thin epoxy flooring. The fiber is spread, epoxy is poured on it and spread by roller or plastic. Make sure there are no air bubbles between the fiber and the plywood. If you notice a bubble, set it aside and get rid of it. It is sufficient to use enough epoxy flooring to make the fiber transparent and the excess is harmful. After reaching the jelly stage, but before freezing, apply the next layer in the same way. On the other hand, the fiber tape is somewhat different in practice, as it is usually coated on the paste. First, spread the tape over the fresh paste and place it well with a roller brush or finger. We don’t want air bubbles, but still don’t deform the soft paste while doing this job. Then I suggest you wait 5-10 minutes. The tape will absorb some epoxy flooring from the paste below and the parts that absorb enough epoxy floor coating will become transparent. Apply thin epoxy to non-transparent parts until they are transparent. You can use normal or roller brush. Again, be careful not to press the paste too much and deform it. Finally, see if the air bubble is released again and destroy it if you find it.
Lamination
It offers an elegant solution for many problems encountered in lamination boat building. For example, you may need a thick plywood like D4’s rudder blade or swinging, and you may not have it. Or it may be necessary, for example, to curl and bend a thick wood. If it is impossible to give the desired shape to the piece of that thickness, the shortest solution for amateurs is lamination, that is, the method of obtaining the desired thickness with many thin pieces glued on top of each other. For lamination, first clean the parts, sand, wipe the dust and thoroughly wet both surfaces with fine epoxy floor coating. Then cover one of the surfaces with a thickened epoxy thickened with ketchup or mayonnaise and attach to each other. You can use torture, weight, whatever you find. There are a few things to look out for. If the laminated epozy floor coating pieces are small or thin and long, you can use thicker epozy floor coating (mayonnaise). On the other hand, if you stick pieces with large surfaces together, it is better to prefer a thinner consistency (ketchup). The reason for this is to reduce the possibility of air bubbles remaining. Since this is a major problem for large surfaces, drill a bunch of holes in the top surface to avoid trapped air (I drill a hole every 10cm x10cm). Then gently attach the pieces together and rest assured if the spectrum floor coating mixture leaks up through the holes. Last but not least, the strength of the joint is not proportional to the fastening pressure. In fact, the opposite is true. You will get a weak bond if you tighten the tortures and remove the remaining epoxy completely. When bonding with epoxy, it is necessary to fasten the parts so that they do not move. As a result, do not apply too much pressure!
Bonding
The same to be done is the same as described in lamination. Cleans the areas to be glued and wet with sandpaper and thin spectrum floor coating epoxy. Then bring the epoxy flooring to the desired consistency. If you are not working against gravity, mayonnaise or even ketchup consistency is suitable. If you are working against gravity, it is useful to make the epoxy floor coating a little thicker and to bring it to the consistency of shockella so that it does not flow. Then, you apply the epoxy to the adhesion area and attach the parts so that they don’t move. Be careful not to over-tighten.
