Can you apply stain in extreme heat?
As you may well be aware, summer is in full force. Many places in the United States and around the world will see record high temperatures this season. For those working in the log home industry and log homeowner “do-it-yourselfers”, this time of year presents considerable challenges when applying stain and finishing products.
We found an excellent article from Permachink (below) called “What Hot Weather Means for Exterior Finish Application” that provides great information on staining in the extreme heat.
Keep a sharp eye on the weather and look for opportunities where the conditions are favorable for application. For most stains, 70 degrees Fahrenheit is the optimum, with the safety range from 50 to 90 degrees Fahrenheit. Stains do vary, so check the label first. Avoid high humidity and staining on hot surfaces. Keep in mind that the outside air temperature and surface temperature are two totally different things. For example, depending on the type of surface and direct sunlight exposure, the surface can be up to 50% higher in temperature than the surrounding air. Our recommended application temperatures are based on the surface temperature and not air temperature.
COMPLICATIONS TO APPLYING IN TOO HOT OF CONDITIONS
If you are in a hurry and decide to move forward regardless of the recommendations, there will likely be consequences. If the surface is above 90 degrees Fahrenheit, the stain may dry too quickly, potentially causing lap marks, uneven penetration and have compromised adhesion to the surface. It is okay if the temperature rises after the stain is applied and has begun to dry. Additionally, avoid application of products in direct sunlight. The sun will often cause a wall to heat up well beyond the recommended surface temperature. For a dark-stained wall it is not uncommon for the surface temperature to be in excess of 140 ֯F.
COOL IT DOWN
Consider shading an area to cool it down. Some experienced applicators have recommended starting with the shaded west wall in the morning and in the evening finish with the shaded east wall. Other walls that have been covered and protected can be done last. Furthermore, consider keeping your products in a relatively cool place just before using them. Moderate temperature of 60 – 80 ֯F just before application is recommended. When working with the sealants it will help to improve contact on the top and bottom edge and give the applicator more working time before the product skins over and becomes more difficult to work with.
KEEPING AN EYE ON MORE THAN THE JOB
When it comes to extreme heat and sun exposure, your health and safety are paramount. Some of the more common signs and symptoms of heat exhaustion include confusion, dizziness, fatigue, headache, muscle or abdominal cramps, nausea, vomiting, or diarrhea. While working out in the heat be sure you are staying hydrated. Drink plenty of water, avoid caffeine and other dehydrating beverages. The use of a high SPF sunscreen, hats, long sleeve shirts and pants will help reduce the damaging effects of radiation from the sun.
