I know how exasperating it can be when your paintwork is full of imperfections and you’re not sure why. Fortunately, the remedy is usually pretty straightforward.<\/p>\n\n\n\n
Problems while painting are mostly caused by a failure to properly prepare the surface. If your paint is separating while it’s being applied, it’ll be due to a lack of silica, lack of adhesion, over-thinning or using the wrong type of thinner, or a lack of primer.<\/strong><\/p>\n\n\n\n This article is going to take a closer look at the 4 reasons for paint separation before showing you exactly how to fix the problem at the end.<\/p>\n\n\n\n Paint should not separate after an application if you have prepared the surface, used the right paint, and applied the paint correctly. Here are some reasons why your paint is separating on your surface.<\/p>\n\n\n\n Another name for paints containing silica is mineral paint. Mineral paint includes pure silicate, dispersion silicate, and sol-silicate paints. Silica is common in many types of construction materials, including sandpapers, concrete, and paint.<\/p>\n\n\n\n Paint manufacturers and professional painters prefer silica-based products. Silica helps with the structural integrity of the material and enables it to last longer in harsh environments. You also find silica in caulk since it is weather and corrosion-resistant.<\/p>\n\n\n\n Silica offers significant textural properties to oil-based paints without affecting the color. Silica helps oil paint to dry harder, making the texture waterproof while still letting the walls of your property breathe. The silica also helps the paint to bind better when dry – since the paint can bond directly with solid silica particles.<\/p>\n\n\n\n You want your surface to have no contaminants and to offer the best possible conditions for your paint to stick. Painting water-based paint on an old-based painted surface is one of the biggest mistakes. Oil will reject any water in paint and cause it to pool together in droplets, and the same applies to primers.<\/p>\n\n\n\n Even without the surface being painted, dirt and oils condensing out from the pollution in the air will have the same effect as an oil-based paint. Oil-based paints should stick to most surfaces, but they will struggle to cling to latex paints. Latex paints will expand and contract in the heat, oil-based paints will not, and this will cause separation and alligatoring.<\/p>\n\n\n\n The paint manufacturer will specify the type and percentage of thinner to mix into your paint. Adding the wrong thinner, such as water, into an oil-based paint will destroy the mixture and form large patches as the paint tries to dry on your surface.<\/p>\n\n\n\n Even if you use the correct thinner, you need to stay within the recommended proportions. Too little thinner and the final mix will be difficult to apply, and it will struggle to sink into the material you are painting. Too much thinner, the paint will take a long time to dry, it will drip more, and reduce the paint’s adhesive powers.<\/p>\n\n\n\n Primer helps to create a clean and sticky surface for your paint. Materials like metal and plastics resist the attempts of paint trying to sink into their surfaces, but a primer sets up a new surface. Primers seal in the material you are painting, giving it greater protection from moisture and general damage.<\/p>\n\n\n\n A primer prevents the paint from separating as it dries and should also prevent the paint from cracking and peeling. When using a primer, ensure that you do not mix primers for oil-based and water-based paints, and check that you are using the correct primer for your paint.<\/p>\n\n\n\n If you leave the primer on too long, the primer will lose its tackiness, and the adhesion of the paint will be poor. Painting on top of the primer before it dries will lead to your paint and primer mixing, which will spoil the color and the finish.<\/p>\n\n\n\n Check the base of the paint that you are using (whether it is an oil- or water-based paint) and buy the appropriate primer. Wait for the surface to dry between coats and, if possible, use a roller rather than a paintbrush.<\/p>\n\n\n\n Follow this step-by-step guide if you are having trouble with your paint separating:<\/p>\n\n\n\n Note<\/strong>: When painting any surface, make sure that it is dry and stays dry while the paint cures. Check the weather before starting, and do not paint in rain or when the humidity is over 75%.<\/p>\n\n\n\n4 Reasons Your Paint Is Separating<\/h2>\n\n\n\n
