Although can use time of the epoxy resin will have considerable shortening, using slow crosslinking agent will get longer can use time, slow crosslinking agent from open bags to gel before, penetration dramatically with more than 205 crosslinking agent.
When epoxy resin crosslinking completely, slow crosslinking agent will be as a wet resistance material, and keep the strength and effectiveness all, then we feel it is far more add any solvents to the advantages of epoxy resin. Remove epoxy resins unlinked or uncrosslinked. You should remove uncrosslinked epoxy resin.
You can use a lot of materials such as hard metal or plastic squeegee to scrape off the hot, hot, surface of the epoxy resin. You can also use thinner paint, acetone, or alcohol cleaning residue. Please pay attention to safety warnings when using solvents and provide adequate ventilation. It is a good idea to apply a wet epoxy resin with an improved adhesive brush to apply epoxy resin to wood (in the direction of the wood grain). Dry the solvent before applying it.
Remove the fiberglass cloth from the epoxy resin and use a hot gun to heat and soften the epoxy resin. Start a corner or edge in a small area. Use heat until you can slide a putty knife or chisel (about 50 degrees) under the cloth. Heat up the front edge of the parting and use a pair of pliers to pull or hold the edge of the cloth.
In large areas, use a practical knife to cut the coating into narrow strips and remove it. The final surface texture can be repainted with epoxy resin. It can also be removed or left as follows. Remove cross - linked epoxy coating with a hot gun to soften epoxy resin (50 degrees). Heat a small area and open the coating with a knife. Polish the surface to remove the remaining material. Ventilation should be provided when heating epoxy resin.

Because it reduces the dust of sand, people prefer wet sand, which will allow you to skip step 2. After you are satisfied with the texture and level of the surface, wash the surface with fresh water. Wash water should be on the surface evenly without water beads or fisheye.
If you wash the water above the water bubble (a sign of pollution), wipe the area with the solvent and dry it with a paper towel until the water droplets or fish eyes are removed. After the surface has been thoroughly dried, continue your final coating.
Reducing the likelihood of contamination, it's a good idea to start coating in the last 24 hours. All these can be explained from the manufacturer of the coating system. A good design is provided by a professional and is a test to calculate the surface readiness and compatibility required by the completion system. The final coating is coated with a layer of epoxy resin barrier coating like paint or varnish. The ultimate coating function is to decorate the surface and prevent the epoxy resin from being exposed to sunlight.
In this way, the final coating enlarges the moisture resistance of epoxy resins, which also provides a long period of use and provides a stable final coating. Two layers of coating together make up a more durable system of protection than any of the coatings themselves. One of the main considerations when choosing a final coating is daylight protection.
Ability long-term uv (ultraviolet) barrier coating depends on the resistance to uv coating itself, and it contains pigment, or its obstacles in epoxy resin coating is formed on the surface of the shield of uv filters. A layer of high gloss final coating has a higher ability to reflect light than the surface of the hair.
When all the conditions are equal, a white surface, especially a smooth white surface, will last the longest. Most types of coatings are compatible with epoxy resin. Completely cross-linked epoxy resin is an almost completely inert plastic. This means that the solvent or most of the paint that reacts with it will not soften it and expand.
However, it is still a good idea to do a test to guarantee the compatibility of the coating. The coating type latex is compatible with the epoxy resin and their work can prevent the epoxy resin from being irradiated by uv. The application of latex paint on many buildings can be the most suitable coating for the application. But their durability is limited.
