I just had a fibered aluminum reflective coating added to my flat (very minor slope) roof. I had read that these normally require 24-48 hours to cure depending on conditions, but i'm seeing that we will likely get a decent amount of rain in the 12-24 hour range after application, and even more in the 24-48 hour range. Weather is always a little spotty and tough to predict so I wouldn't blame them for trying today. My questions would be 1) how bad will it be for the coating if it rains less than 24 hours after application (currently sunny, temp around 85-90 with humidity just over 50%)? and 2) if it does rain heavily prior to fully curing, do roofing companies normally provide a re-application or is that something I will have to pay for separately?
If one were to discover a leaking section of fabric during a rainstorm, a highly effective solution is to rub wax (candle, ski wax, paraffin, etc.) on the fabric. No need to heat it: rubbing cold works fine. It is better to apply from the outside, but it works okay from the (more comfortable and convenient) inside too. One rubbing generally lasts for several days.
A question that comes up quite frequently this time of year...what happens if it rains after I fertilize? Is it good ot bad? Will it wash out? Should I re-apply my fertilizer?
The answer not very cut and dry, but here is the bottom line: The vast majority of the time, rain after a fertilizer application is not a problem at all. In fact, it is usually a good thing.
Keep in mind (I have said this before), your lawn needs about 1/2" of water after you fertilizer. Water helps "activate" your fertilizer. It helps move the granules deep into the thatch where it starts to break down so that it can be soaked into the root system. So rain after a fertilizer is a GOOD thing.
The issues is when we get too much rain over a short period of time. The 1/2" mentioned above is not a maximum amount, it can be more than that, but it must be spread over a longer period of time.
There are too many factors at play to say exactly how much rain over what time frame is too much...slopes in your lawn, soil compaction, drainage ditches, how thick your turf is...all of those can play a factor in the amount of wash out you can have.
If you have applied a fertilizer and rain in the forecast is a concern to you, there is something you can do...run your sprinkler system!
That might sound crazy, and this is the only time you should ever run your sprinklers before a rain. However, as I mentioned above, water helps move the granules down deep into the thatch where it is much harder for them to be carried away. Granules also get sticky as they break down which will help hold them in place.
So to recap...rain is good most of the time and should not be a concern. But if it is a concern...run your sprinklers!
This is one old wives' tale that is based in some truth, but it may not be why you think. Leaves of a tree do sometimes flip over before it rains, but it's not because of anything the leaves themselves are doing in anticipation of the precipitation. Instead, it's a response to the weather conditions that precede some rain events.
Because of this, the leaf flipping is usually a sign that rain is imminent, not part of the long-range forecast, according to WGN-TV's Tom Skilling. This is because the leaves are changing position because of weather conditions that typically develop just before rain moves in.
One of the primary factors that can cause leaves to flip over before it rains is wind. As summer storms and rain events move in, gusty winds often precede them, causing leaves to flip over and show their silvery side, according to the Ohio State University Extension.
Another factor that can cause leaves to turn over just before it rains is humidity. As you've no doubt noticed, rain and storms are often preceded by or accompanied by humid air. The humidity can soften the leaves, causing them to hang more limply on their branches, Farmers' Almanac reports. The softening of the leaves can also make them hang in a flipped position or flip more easily in the breeze.
And flipped leaves aren't the only signal plants may provide of the upcoming weather. Like leaves, pine cones also react to humidity, so if you see them all closed up it's a sign of high humidity levels and possible rain. Flowers, too, are said to be more fragrant before it rains because the increased humidity makes their scent stronger, according to the Ohio State extension.
"Glyphosate must penetrate the leaf surface to provide effective weed control. While absorption occurs relatively quickly, rain after an application can wash glyphosate off before it has a chance to enter the leaf. The rain-free period required to prevent reduced activity is in uenced by the susceptibility of the target weed and the glyphosate rate. Small weeds of a sensitive species will require a shorter rain-free period than large or dif cult to control weeds. A 30-minute rain-free period may be adequate under ideal conditions. When spraying larger weeds, however, several hours between application and rain may be required to avoid reduced activity. Differences in rainfastness among glyphosate products are generally small. Adding more surfactant appears to have marginal benefits on the rain-free requirement."
Glyphosate is a systemic herbicide. It really only needs a few hours to get into the plant before a rain. It is not a quick killer in basic formulation, but absent resistance, it kills the whole plant. Farmers started using it in the 70s using contact applicators to brush it onto Johnsongrass. Roundup would take a week to kill it, but it got it all, down to the rhizomes that produce new plants underground.

Two things to keep in mind:
1. Some pesticides (including herbicides) are limited to one application per season, even if washed off by rain. If efficacy is reduced due to spraying in the rain, options for second applications may be limited.
2. When dodging rains during weed management season, keep in mind that a sprayer sitting idle with product in the tank will increase the risk for product contamination. Read more.
Robert Rauber, a professor of atmospheric sciences and the director of the School of Earth, Society and Environment, said that the oils fall into the soil and interact with bacteria. He explained what happens to these oils when it rains.
I am in the process of sanding and staining a new deck (built in June) but the weather is not being very cooperative. I know stain needs to sit 48 hrs before being rained on, and that wood needs to be dry and sanded before hand, meaning 24 to 48 hrs after a rain. So at a minimum I need 5 clear days, assuming 1 day in the middle for sanding and staining.
I am planning a 2 pass sanding job with a belt sander using 40 grit and a finish pass with an orbital using 80 grit. My question is, can I do my rough pass before a rain, and then do my finish pass 48 hours after the rain, and then stain? Or am I wasting my time sanding before the rain at all?
I've done deck railings and have split the sandings with rainfall in between with no problem. You just have to make sure the wood's dry before the second pass. Weather never cooperates when trying to sand/stain a deck. Get a waterproof tarp and keep the deck covered while you're working on it. It will save you a lot of time waiting for it to dry out after rain. Just make sure to allow for air flow. I always have a tarp handy when sealing decks.... you can't rely on the weatherman. Good luck.
Why? Because heavy rain waters lead to run-off and will more or less wash out your fertilizer before it has a chance to break down and be absorbed. Not only will the fertilizer be ineffective, but you will have wasted the money you put into it as well.
If you are using your irrigation system to water in fertilizer and notice that water is beginning to flow through the yard and into the street or storm drains, turn the system off and allow the water to seep into the soil. Then wait a few hours before watering any more.
If you are using latex acrylic paint you need at least two hours of sun for paint to dry before the rain comes. If heavy rain is forecast or several days of rain are coming in the next few days, you will need about six hours of good sun to dry the paint thoroughly enough to not be affected. Paint will dry to the touch in one hour or so depending on the heat of the day. It takes about five days of normal weather for paint to dry all the way through and for the paint film to reach its maximum hardness and durability.
If it rains before the paint surfaces dry the rain will wash some of the paint off that were painted last. This is rarely a problem because the surfaces, when dry the next day, can just be repainted.
However, you really have nothing to worry about. Most of the products used in Houston pest control are completely insoluble, water does not affect them. However, pest control can be impacted if it rains heavily for several days.
When it rains, the ground softens up and most pests such as ants, come to the surface to escape the moisture. With the pests exposed like this, it makes any pesticide that much more effective as we can apply it directly.
