Summer - It's a wrap! Talk a little about the weather?
The outdoor painting season is now over, so it's time to bring paints, supplies and painting projects inside and remind our customers about the proper storage of paint
Now is a good time to bring the paints from the cottage, yard sheds and garages to the warm place.
Frozen or frosted water-based paint cannot be revived, and painting with such paint has a negative effect on durability and smoothness of the surface.
Also remember that you should not leave the paint in a cold car overnight, or on a frosty day in the back seat during a shopping trip. Water-based Frenchic paint is prone to freezing and frosting.
Painting outside when the air is cool and damp is not a good idea.
Even if it's still sunny during the day, it's cold at night and heavy dew rises on the freshly painted surfaces.
In order for the paint to harden (dry) effectively, the temperature must be at least 10 °C (even overnight) for at least 48 hours after painting.
Dewy and rainy conditions are also not a good option.
Brief instructions
- Check the weather , and also see the weather forecast for the next few days. Avoid extremes of temperature and humidity.
- Conditions affect : The paint surface must be dry, and the paint must have enough time to dry and harden.
- Avoid problems: Weather that is too hot, cold or humid can spoil the final result and weaken the durability of the paint.
- Don't forget storage : Close the paint can carefully and store it away from extreme temperatures. The best place for storage is +10-+20 even temperature.
Painting weather and conditions - When is the right time to paint?
Frequently Asked Questions:
Painting outside should usually be done in warm weather - painting in cold or damp conditions is not recommended. But too hot weather can also cause problems! Here are the most important things in a nutshell:
- Check the weather during the painting and for the next 48 hours.
- Avoid painting in extreme temperatures, direct sunlight, cold or damp conditions. In an open can of paint, a thick crust easily forms on the surface of the paint, and the tears on the edges of the paint can dry out and fall into the paint can.
So keep the lid on the paint can so that impurities do not fall into the paint and store the paint can in the shade.
- Remember that depending on the season and location, exterior painting is not always the best idea.
Make sure the surface is dry
The first and most important rule: the painted surface must be completely dry before applying the paint.
Exterior wood and other porous materials can absorb moisture and require a long drying time after rain or preparation - sometimes even several days if the weather is not favorable. This problem is accentuated in early spring and late autumn.
Anticipate and move the furniture indoors to dry in good time.
Drying and initial hardening
All paints need time to dry and harden properly.
This is not only important in terms of durability, but it also guarantees a smooth and even end result.
Why? Because the paint's moisture must evaporate effectively in order for it to adhere to the surface and harden properly.
This requires the right conditions that support both drying and hardening of the paint. Let's dive deeper into these conditions...
What weather and conditions are OK for painting?
With these tips, you will ensure that your painting project will be successful with the grace of the weather!
Always remember to check the weather forecast and protect your paint properly. Painting can be fun - as long as the conditions are right.
Make sure the weather is favorable during the painting and also for the next 48 hours - remember that the temperature can drop significantly at night!
Weather too hot?
If the air is too hot, the surface of the paint may dry too quickly. This can cause an uneven texture and hinder the curing process of the paint, as the underlying paint dries more slowly. In direct sunlight and heat, painting is not really even possible, as the paint dries quickly both on the brush and in the paint can.
In addition, the heat can cause the water in the paint can to evaporate too quickly and the paint quickly becomes too thick.
This can lead to thickening of the paint and make it difficult to apply it evenly - and possibly cause color variation.
Avoid evaporation in the jar by transferring the necessary amount of paint into a clean container (remember to mix well first!) and close the jar tightly. Do not leave the jar or container in the sun!
The target temperature for painting and for the next 48 hours is between +10°C and below +32°C.
Weather too cold?
Painting in the cold can also be challenging. Some paints may thicken in the cold, making them more difficult to apply.
In addition, the cold slows down drying, which can affect the durability of the final result and cause a white "blooming" on the surface.
Extremely cold weather can even freeze water-based paints, rendering them unusable. Frozen or frosted paint should not be revived by thinning or mixing - if the composition is grainy, do not use the paint.
Make sure the temperature is at least 10°C during the painting and the first 48 hours (remember that the temperature can drop at night!).
Too humid or humid weather?
Moisture slows down the drying of the paint. Humid air prevents moisture from evaporating from the paint and slows down hardening. This is true in all kinds of temperatures. In the summer, paint indoors in a well-ventilated space.
As in cold weather, paint drying slows down in humid conditions as well. This can prevent the paint from curing properly and cause a white gauze on the surface.
What is the right time of year for painting?
Taking into account all the points mentioned above, certain seasons are not necessarily the best time for exterior painting.
In Finland, it is recommended to schedule exterior painting between spring summer and the warm beginning of autumn, when the weather is usually more favorable, but even then you should be prepared to take the painted furniture to shelter from the weather after painting, so that even drying is guaranteed.
A small reminder about storage
The storage conditions of the paint are also important:
- When you pick up paint, you don't leave the can of paint in a cold car on a frosty day during a shopping trip. Water-based paint freezes and freezes easily, and frozen paint can no longer be revived.
- Close used cans carefully after use to prevent water from evaporating from the paint. The result is a thick paint.
- Protects paints from moisture, cold and heat during storage. The best place is an even temperature and dry space.
- Do not store paint in outdoor storage or in the garage in the winter, now is the time to save the paint in a warm place at the latest.
- When you use paints again after a longer storage period, first mix the paint strongly and for a long time.
If the composition of the paint seems smooth and correct after careful mixing, and the paint does not smell bad, you can very well test how the paint spreads on a test piece. If everything is in order and the color looks right, you can continue painting.
Otherwise, we do not recommend painting with, for example, grainy compositions and paint with a nasty smell. Such paint is spoiled.
Spoiled paint affects both the shade and the durability of the surface and the beautiful surface and applicability of the end result.
With these tips, you will ensure that your painting project will be successful with the grace of the weather!
Always remember to check the weather forecast and properly protect and seal the paint.
Painting can be fun - as long as the conditions are right.
