cure time


i will be finishing up a aggregate sealing job .Is clean and dry but wanted to know if it will be ok as to dry/cure time before rain.I will be sealing it around 9 am and high will be 81 for day low humidity ..later around midnight some showers into next day..temps from then on will be 50s for long time.

Should 8-12 hours with 6 in full sun be enough before late night then early morning rain?

Personally, with any coating on any surface, I like to at least have 24 hours without moisture hitting the new coating.

cure time


ok thanks..i went ahead and did all but small last area. would like to try and get it in early morning but afraid it will be too close to a shower in late afternoon.It says 24hrs dry time.does the high winds and 75- 80 degree temps help with drying it faster ?

It will dry MUCH faster with wind and heat, sometimes too fast.

DRY time is much different than Cure time, ( just for hidden's information)

Most Tech Data Sheets advise not to paint 24 - 48 hours in front of rain. The paint will withstand rain, however, depending on weather conditions, it won't be fully cured for 4 - 6 weeks on average. During that time frane, the film is considered 'tender' and if anything can happen it's probably going to be bad...

FYI - Sherwin Williams has a lifetime paint that's formulated for cold weather / close to rain conditions - Resilience. You can paint 1 hour before rain hits and be ok in most conditions, or paint in as cold as 35 deg. temps if I remember correctly.

While it is true that a 100% Acrylic Product will form a film in cold temperatures (35-38F) it still has to go through a curing cycle. If S-W works for you, then excellent; just be sure that there isn't too much 'fine print' on the label making it a marketing ploy.
