Topside boat paint can be applied anywhere except the boat portion that remains underwater, the bottom side of the boat. Except for the bottom side, the paint can be applied to the interior, exterior, the bridge, and anywhere else.

There are different types of topside paints such as skid paint, non-skid paint, there are boot stripe paints which are used to make stripes, etc. Actually, there is a lot to discuss topside paint but for now let’s go to the point.

Easy Techniques and Expert Tips for Topside Painting

Before we get started with expert advice, there are a bunch of basic things that you need to ensure. First make sure you pick the right and suitable topside paint for your boat, compatibility and the quality of the paint will play a major role. The previous paint of the boat needs to be compatible with the new paint, this is extremely necessary if you want an effective and efficient top-side painting.

Then comes the equipment, without the right equipment you won’t be able to do the topside painting properly. By equipment I mean, the sprayer, brush, eye-protective gear, cartridge type respirator, sander, masking tape, primer, etc. Make sure you have all the items.

And the last thing you need to consider is the environment within which you will be doing the painting. You must have enough light. And before painting damp the floor if that is dusty.

However, there are a bunch of topside painting methods which people use. But among them there are two that have proven to be very effective and most experts follows these two methods.

  • Thinning Topside Paint for Rolling & Tipping
  • Rolling & Tipping Topside Paint Like a Pro
  • Thinning & Spraying Topside Paint

That’s pretty much all you need to think about before getting started with the topside paint.

Thinning Topside Paint for Rolling & Tipping

Topsides paints come thicker and applying the paint on the thickest form would be messy since it wouldn’t lay down or flow around easily. And when the paint is stubborn to lay smoothly, the brush or roller you use will start dragging and that will get you an uneven, unsatisfying finish. So thinning the topside paint before applying it must according to the experts.

There are different ways in which you can thin down the paint that will enhance the consistency of the paint and will enable you to apply easily. Different people use different kinds of thinners, but which one should you use that will depend on the paint you want to thin. There will definitely be a manufacturer recommendation, whether labeled in the paint bucked or in the manual (that small book or page comes with the paint).

The manufacturer recommends a suitable thinner along with the suitable amount. Not only that, but the manufacturer also recommends the right temperature as well within which the thinning will be much better. So don’t hurry, read the manufacturers recommendation with patience and if there is anything you are confused about, reach to the manufacturer through the customer service.

Once the thinning task is done with the right thinner, most people would put the thinner aside and get started with the painting. But the experts suggest keeping the thinner during the staging process.

It doesn’t matter how well you thin a paint when painting you will be required to do little more thinning, you will feel the need of thinning suddenly when the brush or roller will start dragging. That being said, do not over-thin, otherwise, the paint will streak.

Rolling & Tipping Topside Paint Like a Pro

There are different methods of applying the paint but among all of them the most effective one is Roll and Tip. Most of the experts follow this method since it is the most effective one. The roll and tip painting method requires two people. One will keep applying a thin paint coat with the roller and the other one will remove the roller stipples right after the roller passes.

When you do coating with the roller that leaves some texture like orange peel, the second person’s responsibility is to remove those textures.

Make sure the roller tray is filled with enough paint so that you can cover a large portion. If you have chosen the Roll and Tip method, one thing you should keep in mind is, you have to keep painting, you can’t stop otherwise the paint will get dried. And when the paint is dry, the brush will start dragging. So make sure you start with full preparation so that you don’t need to stop in between.

With this method, the painting will be done quickly and there will be less chance of over-doing. However, if you are a beginner, have never done this, you can do some practice painting on any coated plywood.

Enter a rhythm no matter what style you choose and keep going or the paint will dry out and pull the brush.  A few more things to keep in mind:

  • Your roller and brush will be solvent resistant, or paint solvents will destroy them, and they will separate.
  • Large cell foam rollers or other types of rollers create other texture problems, including bubbles and sags.
  • Mix enough paint to do the entire section at once to plan for logical stopping points.
  • Holidays are no picnic when you’re doing a rolling and tipping session, but they happen. If you get them, leave them alone. Touching them up will make them worse. After sanding, you’ll cover them with the next coat.
  • Touching of anyone will make your paints worse. After sanding, you cover them with the next coat.
  • Rolling the paint too often should be avoided. Solvents can get stuck to the bottom of the film by eliminating the possibility of run and sags in the paint when it becomes skin and affects the healing time.
  • Apply 2-3 coats in this manner for proper healing and allows any necessary growth in the coat.
  • Wipe again with a damp-free rag with the paint manufacturer’s recommended solvent. Allow the solvent to flash before applying the next coat.
  • After the last coat, remove the masking tape afterward and for the best-looking line - no more than 1 hour earlier.

Thinning & Spraying Topside Paint

Another convenient topside painting method is spray. Spraying the paint is easier and it is fun as well. But when using polyurethane paint you have thin one part of that with the recommended thinner by the manufacturer.

And also you have to be very careful about the weather condition as well. The temperature and humidity need to be according to the manufacturer's recommendation.

How much thinning you need to do that will depend on the paint. Do not over thin, that can cause sagging. However, before you start painting with a sprayer you have to ensure you are in a well-ventilated area. The wind needs to be moderate, otherwise, the painting would be very awful.

The proper spray technique concentrates on three things: spray patterns, trigger technique, and overlapping technique.

The target for the spray pattern

When spraying, hold the gun at an uninterrupted distance from the surface and keep the arm straight, even at the target surface for the finish. Instead, take it, but the end will be unequal.

Press and release the spray trigger

Start firing the gun before you press the trigger and continue your arm motion after releasing the trigger to avoid the added concentration at the beginning and end of each stroke.

Proper overlapping technique

Covering the paint overlaps by 50% each time the spray passes. Point the spray tip at the bottom end of the previous spray pass to ensure efficient overlap.

One most important thing, you have to choose the right sprayer. There are different types of sprayer and you have to go with the one that the paint manufacturer recommends. There will be a recommended angle of spray, pressure, spray tip size, spray tip type, and flow, for the best result you have to go follow that.

FAQ

Can I use topside paint on the bottom of my boat?

You can only use topside paint on the bottom of the boat if that doesn’t require anti-fouling properties. Otherwise, you can’t.

Topside paint cannot inhibit that growth which is why there is no point of using topside paint at the bottom.
