The General Finishes topcoat is the first option on the list. The following sizes are available: 1 Gallon, 1 Pint, 1 Quart, and 5 Gallon, and the available variants include Satin, Gloss, Flat, and Semi-Gloss.

For simplicity’s sake, we’ll take a look at the option with the 1-quart size and the flat variant.

This water-based topcoat is one of the more long-lasting options for those who want to have a sheen that remains on, regardless of the use of the item.

Top Coat for Painted Countertops – Buyer’s Guide

This is a reference for those that want to know about the differences between the coatings mentioned on the list, as well as basic information on what needs to be done when applying the coating, understanding durability, best surfaces for each type, and the negatives they present.

Types of coatings for painted countertops

  • Polyurethane: It should be noted that this kind of coating comes in either water-based or oil-based variants. Ones that are water-based make the finish look a lot clearer and less odor after applying the polyurethane.

    It takes about two or three hours to get the coating done, and your tools can work with water to get the process done with 4 coats. Said coats will look natural, as they add more to the surface texture of your projects. It’s a lot more expensive and consists of 35% solids.

  • Oil-based polyurethanes need fewer coats, but they do leave an amber glow instead. They take a lot longer to dry, and they leave an odor, which means that it’s recommended not to step in the area for an extended period of time.

    Even so, your projects can have a nicely done glow at the end. They can remain a lot more affordable as one of their positives, and they consist of 45% solids. The biggest drawback to using them is that they’re likely to leave a yellow tint on surfaces with lighter colors, so they’re better used only on darker colors.

  • Epoxy: Another kind of topcoat in the market, this is a lot faster to work with compared to its polyurethane counterparts.

    Additionally, they are not meant to be used for outdoor furniture due to the risk of having the items yellow from UV exposure. There are other issues with epoxy, such as bubble susceptibility and heat tolerances. Additionally, it does not turn yellow, is compatible with any painted surfaces, fills irregularities, durable and environmentally friendly after hardening. You can add paints to the epoxy for an amazing look.

How many layers do you need to apply?

It depends on the kind of material you are working with.

  • With water-based polyurethanes, all that matters is doing the work for at least 4 hours and make sure the four coats are applied nicely.
  • Oil-based polyurethanes require more time, and no one can step into the areas that a project is worked on, even when there are fewer coats needed.
  • Epoxy resin requires only a bit of work to be put into the coats to make sure they remain perfect before they dry.

Some tips to apply polyurethane

This is a bit of advice for some that are new to the project. In terms of water-based polyurethane, it’s recommended to be sure the mix is done right, especially given how often a project will be given coats.

Afterward, the next thing to do is to leave the material to dry for an extended period of time. As for polyurethane that is oil-based, it needs a good amount of mixing before it’s applied, and it should take longer for the coats to dry.

Epoxy Resin Vs. Polyurethane

Here is a comparison between the three materials:

In terms of the finish, water-based polyurethanes are a lot clearer, oil-based polyurethanes leave off an amber glow, and epoxy resin tends to look more reflective. Regarding the odor, water-based polyurethanes have less odor left from applying from handling the substance, oil-based leaves a strong odor, and epoxy resin can go from either harmless to poisonous, depending on the type used.

As for the coating amount, it’ll take:

  • 4 coats for water-based,
  • 2 with oil-based,
  • and 2 for epoxy resin.

Depending on the surface you’re working on, some of the coats will likely cause the projects to yellow from either applying it on the surface with a poor batch or if it’s not supposed to be put on there.

Also, there is more to check on with epoxy resin than there would be with the other topcoats. They include things such as heat tolerances or bubbles.

A final trait of the material is the necessity to prevent any scratches from developing during the coating, which requires using tools to keep everything finely done during the process.

Frequently Asked Questions

How long do bottles last?

It depends on the amount of work you do with your projects. If it’s a tabletop or a specific project that’s not too massive, then the bottle should last a good while. If it’s a much larger table or surface, then a bottle would have most of the liquid used for as much as half or more than expected. Additionally, it also depends on the size of the bottle or can that you have, where smaller cans are likely to have the liquid deplete while larger mixes won’t have such an issue.

When should I apply more coating again?

Another set of coating will be needed every quarter or half a year, though this solely depends on the wear and tear the item receives from people using it or moving other items around the project. Look at the first FAQ regarding whether or not you’d have enough for a new project depending on the quantity remaining (bottle/can size is also put into consideration).

Where’s the best place to apply the topcoat?

It’s best to apply your top coat on a project away from sunlight to have better results, even if it’s an item that may normally be outside. The temperatures of the outdoors and the weather may limit what you are trying to do.

Can any topcoat be freezable/flammable?

If a topcoat freezes more than three times, then it cannot reform. As for its flammability, it’s able to withstand heat on some items that generally become warm from use.

Should there be any preparation done before the topcoat is applied?

It’s recommended to clean your projects before applying the topcoat. Wax is not recommended due to it affecting the adherence of the topcoat, though other cleaning products are perfectly fine.

How to handle imperfections already found before the application of the topcoat?

The application of the topcoat can further reveal the imperfections more than they were before the topcoat was added. This can help you remove said imperfections while adding your coats.

What is the best way to remove the topcoat?

Use solvents that are aliphatic, aromatic, or even an Isopropyl Alcohol with a high concentration to remove the coat; it’s advised to keep in mind how many coats were added before the process begins, as the thickness of each coat and the amount will add more time to your removal process.

Is it recommended to sand the surface of a painted tabletop before and between the application of the topcoat layers?

Yes, it is recommended to sand the surface of a painted countertop before you apply the topcoat layers. Doing so helps make the surface rougher and shine-free, so the layers apply better during the process, though the dust left from the sanding must be removed with either paint thinner or mineral spirits.

After the first two coats are done, you should also lightly sand the current polyurethane before adding the next two coats, so those can adhere to the ones already applied. This is a process that should be done every six months to help protect the sheen and keep it new.

Conclusion

With everything previously mentioned, laid out in one long but effective referential page, you should get a clear understanding of how top coats work, what versions are available, the differences between the options presented, and the variants that some brands focus on.

Overall, the many choices for epoxy or polyurethane mixes should not be a discouragement for anyone that wants to begin their DIY projects or give some great shine to their painted countertops. If they find a product that’s easy for them to use, or if they find the right item to add for their surfaces, then they should have nothing else to worry about.
