This information can typically be found in the products technical data sheet, or on the can label.<\/p>\n<p>As a general rule,\u00a0coatings should be applied in good weather when air and surface temperatures are above <strong>50\u00b0F (10\u00b0C)<\/strong> for most\u00a0paints and <strong>60\u00b0F (16\u00b0C)<\/strong> for epoxy, resin, and gelcoats\u00a0. Surface temperature must be a least 50\u00b0F (10\u00b0C) above dew point. For optimum application properties, bring material to 70-80\u00b0F (21-27\u00b0C) temperature range prior to mixing and application.<\/p>\n<p><strong>Tips:<\/strong><\/p>\n<ul>\n<li>Make sure to store the coatings inside to keep the temperature in the optimal range prior to application.<\/li>\n<li>Do not let coatings freeze, as this\u00a0may alter the chemical\u00a0integrity of the products.<\/li>\n<li>In warm (hot) conditions be sure to keep the coatings out of direct sunlight exposure.<\/li>\n<\/ul>\n<p>Coatings such as resins and gelcoats that require <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">MEKp<\/a> to be added for curing will require more <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">MEKp<\/a> in cooler conditions, and less <a href=\"https:\/\/www.bottompaintstore.com\/blog\/gelcoat\/gelcoat-did-not-cure-what-caused-it-and-whats-next\/\">MEKp<\/a> in warmer conditions.
