If you\u2019re getting runs\/sags, you may be over-applying<br \/>\nor using too large a tip for your material and technique.<\/p>\n<\/div>\n<div class=\"bps-next-steps\">\n<p><strong>Next:<\/strong> Use the chart below to dial in your tip size by use case and application style.<\/p>\n<\/div>\n<p>There are three main factors to consider when determining the size tip that will produce the best results.<\/p>\n<p>1. First, examine the coating that will be sprayed. Put simply, heavier coatings will require a larger orifice size than lighter ones. For example, primers are usually thicker than the accompanying paint so you should use a 1.7 or 1.8 mm tip to prime most surfaces. Most painters will stay in the range of 1.2 to 2.0 mm unless the paint being applied is specialized. (See chart below.)<\/p>\n<p>2. The next thing to consider is your project surface area. This determines the appropriate fan width that your sprayer will produce, that is, the shape in which the product will leave the gun nozzle. Airless spray guns have more control over the fan width than conventional spray guns because the coating is forced through the tip without being atomized by air. This causes the tip to have a large impact on the fan width and shape. Most boat projects consist of large surfaces and so a wide fan will increase the spray coverage and also provide the ability to spray close to the surface without too much build up. Smaller surfaces will require a small fan width to reduce overspray. This also makes it possible to spray further away from the surface without too much falloff because the fan is more focused.<\/p>\n<p>3. Lastly, consider the <a href=\"https:\/\/www.bottompaintstore.com\/fiberglass-and-gel-coat-repair-gel-coat-spray-gun-and-tools-c-13581_13592.html\" target=\"_blank\" rel=\"noopener\"><strong><span style=\"color: #3366ff;\">spray gun<\/span><\/strong><\/a> that is being used. Make sure that the spray tip you plan on using will be supported by the gun. Most spray gun manufacturers will provide this information in their product overview.

If the nozzle is too large or too small, it can cause uneven application, overspray, or a finish that is too thick or too thin. Selecting the right size ensures better control and optimal results.<\/li>\n<li style=\"font-weight: 400;\"><strong> What happens if I use the wrong nozzle tip size?<\/strong><br \/>\nUsing the wrong nozzle size can lead to several issues, such as poor <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> coverage, inconsistent texture, overspray, or excessive wastage. A nozzle that is too small may cause clogging or slow application, while one that is too large can result in an uneven layer of <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a>.<\/li>\n<li style=\"font-weight: 400;\"><strong> How do I determine the right nozzle tip size for my <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> application?<\/strong><br \/>\nThe right nozzle tip size depends on factors such as the type of <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a>, the thickness of the coating, and the specific spraying equipment you&#8217;re using. A general rule of thumb is that a 1.4mm to 1.8mm nozzle works well for most <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> applications. However, it&#8217;s essential to consult the manufacturer&#8217;s recommendations and consider your equipment specifications.<\/li>\n<li style=\"font-weight: 400;\"><strong> Can I use the same nozzle tip size for different types of <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a>?<\/strong><br \/>\nWhile you can use the same nozzle size for various gelcoats, some formulations might require adjustments. Thicker gelcoats may need a larger nozzle, while thinner ones may perform better with a smaller tip. Always test the setup before starting a large project to ensure a smooth application.<\/li>\n<li style=\"font-weight: 400;\"><strong> Should I use a different nozzle for each layer of <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a>?<\/strong><br \/>\nFor some projects, especially those involving multiple layers of <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a>, it may be helpful to use a different nozzle for each layer. A larger nozzle can be used for the base layer, while a smaller one may be better for final touch-ups and detailing.

A nozzle that is too large may lead to excessive <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">gelcoat<\/a> application, while one that is too small may result in a patchy finish.
