Most finished paintings are created for some average conditions that usually do not exist the day you choose to make your painting! The result of this is that the color does not run out well to leave a smooth surface and you end up in full roll marks or brush marks or dashes or lap marks.
Painting is generally done for what would be an average room temperature or outdoor temperature for the market where these paintings are sold. The problem is that when it is a temperature deviation, either up or down, the color becomes more difficult to brush out or roll on the wall. Indoor water-based paints, Emulsions or Latex tend to dry too fast when the temperature is warmer than average, and the result is that each new section painted may have strokes because the bit has previously dropped out too quickly.
Painter / decorators describe this phenomenon as "losing the wet edge". The painting ceiling can be particularly troublesome as all the warm air of the room rises up to the ceiling and compresses the drying too quickly. If you apply water-based paint / masonry paint to external plastered or similar walls and the weather is dry or dry with a breeze or even worse, if the sun shines straight out on that wall while painting ... you will have a really tough job because These weather conditions mean that you will lose the "wet edge" almost as soon as you apply a roller full of color.
It is best to choose a day that is either too hot or too cold for wall painting etc. If you apply oil-based paint or varnish, especially on a good day, you notice that your color becomes very heavy and the brush tends to draw the painting process much more boring. The reason for this is that the solvent in the color rapidly evaporates under the warmer conditions and it will be necessary to thin the paint a little to facilitate the application.
In order to get your paint or varnish to float, you add historically little water to water-based colors and a bit of time to oil-based colors. It usually makes the color better. There are some negative effects on thin color in this way, for example ... the color loses some of its concealing effect & # 39; which may be a problem when using "weak" hide & # 39; color colors (yellows, reds, etc.) because you probably have to use extra layers to get a finish and block past colors etc.
With shine and other oil-based colors etc, dilution in this way will make it better, but it will kill the firing force and lose much of the luster after some time. Another option would be to use a color additive made to make your color flow out and cover better in less than ideal conditions etc. You can get color additives (sometimes called paint conditioners) for emulsion and oil based paints in most better paint shops. The water-based additive (conditioner) is ideal for any color, but will not be suitable for water-based varnish due to its milky appearance. But it does not change the color or finish etc.
Water-based paint additives are designed to keep the wet edge open and usually make it possible to get a finish without brush marks or streaks. In fact, some water-based colors really help to hide the power in a dramatic way, especially in weak colors such as reds, yellows, etc., where you can save some layers and hard work. Oil-based color additives work well in any oil-based paint and varnish. Check your color to see if cleaning is with white spirit etc and if so, it means that it is oil-based and suitable for that paint.
