how long does osphp need to dry before4 painting?

You can see the rust turn a grayish white color because of the chemical reaction. When it was dry to the touch, I painted it. In the hot sun, it doesn't take long to dry. Once after applying OSPHO, it rained overnight and the rusted metal still maintained the grayish white color from the chemical reaction which showed me that it doesn't wash out once it dries. Hope this answers your question.

I usually apply with a spray bottle and a small paint brush.It gets a white look to it when dry.

I used it at 3;00 pm on oil pipe stem color changed from rusty brown to a black color (wet) and next morning 8 am all was white crystals (dry). I would suggest next day primer. I used terry cloth to apply cause all sponges and gloves shreaded to pieces. May need spot 2nd coat.

As per the instructions on bottle, "let dry overnight". Also, if there is oil (like new metal) or paint, rust scale, dirt, etc., this needs to be removed before applying Ospho - this stuff really works - it does eat the rust. We built burglar bar doors about 2 years ago that are exposed to weather - painted and still looking good.Charles Pilkinton

Depends on the temperature, which should be 70 degrees or greater. 12 hrs or overnight usually does it. It turns light gray then go over it with a fine scotchbrite pad, blow it off and prime & paint.

The can says "based on 70* F - 50% relative humidity. Allow more time at cooler temperatures. Dries to the touch in 2-4 hours, to handle 5-9 hours and fully dry in 24 hours. May recoat in 1/2 hour or after 1 week."

I live in Texas and was working at around 85-90 degrees F. I had trouble with fast drying paints drying in/on and clogging up the sprayer. You might want to try clearing most of the poly by spraying water/detergent solution through the sprayer with the second cup. Then, put the spray tip in water/detergent solution and place a damp rag on the open spray head--not the entire sprayer--while you wait. Certainly, the poly can stay in the cup if it is capped.

Oftentimes I pour into a cup and add water to make a brushable glue. Then I apply a thin coat. It takes about 10-15 minutes to dry. For wood and more porous surfaces a thicker coat is needed. It takes about 40 minutes to dry, depending on the consistency. I really like this glue for a variety of purposes. Good Luck on your project!

It depends on how much you use. If not much, it doesn't take long at all. I just used it with my kids handprints. One of them use a bunch and I just let it dry overnight.

You need to scuff the surface with a scotchbrite pad, remove all the grease with a tac rag, then apply createx base coat sealer - white or black. leave 24 hours, come back, and clear coat it. wait 24 hours, come back, scuff it with the pad again and remove all the dust etc, paint your design, clear coat it 3-4 coats, leave 24 hours. voila!

Depends on how much clay your using. I usually wait a day before I paint on it.

No need, just ensure your floor is very clean and dry. Also ensure temperature is 70+, leave tiles for 2 day in room, then apply.

It all depends on how thick the application ends up. Thin paint-like coats only tend to last 6-15 seconds. Thick strings like letters or filling in cavities will last longer. 1-3 minutes. It shrinks alot while drying, too. So multiple applications may be necessary. No better or worse than other glo-crafts.

shouldn't have to but metallic paints always have longer drying times. Sometimes double especially in damp or cold weather.

Ospho will convert surface rust to black. You still need to sand and prime and paint

The clear coating may be applied no sooner than 24 hours and no later than five days (for best results) after applying the floor coating. Whether you can apply the clear coating after 24 hours depends on how high the humidity was during the 24 hour period after applying the floor coating, as high humidity will slow down the drying of the floor coating. Clear coat is definitely the way to go!

The stuff is thin n very adhesive. You can get away with just coating it on fresh metal. It takes 3-4 days to dry though. Make sure you have enamel reducer for any spills & catch it through the petcock slot in a can because it's pricey.

This glaze is amazing but it has to be applied correctly to the item and more importantly allowed to dry fully. If you're making a piece of artwork say, out of polymer clay, it is best to apply a thick layer without much fussing. In other words, apply a layer and leave it alone until it is fully dry. Then you can apply another layer if need be. I would allow a piece to dry in a cool NON humid place for at least 12 hours. If you are storing an item that has been glazed, please allow adequate airflow to the item. I have had some pieces become tacky for no reason I could comprehend, but I re-glazed the piece and it was totally fine. I don't see an issue with hot climates if you allow the piece to dry for 12-24 hours in a dry, cool place first. If you want to avoid any possibility of tackiness at all, you can create a semi gloss glaze by adding water to the product (in a small cup) and this will reduce your chances of tackiness dramatically. As far as the glaze being heat resistant, I would say it is but please make sure it is properly cured.

for a pin hole size hole (under 2 inches) apply a light coat two to three times allowing 5 minutes between applications. for a larger hole you can apply up to five coats allowing 5 minutes between applications. ensure the AirStop is completely dry before resuming use of the article

I waited 72 hrs and insured that everything was as dry as possible. I found other instructions that said as little as 8-24 hours, but I wanted to be sure that I wasn't trapping uncured material under a paint designed to seal moisture and not breathe. BTW it worked and I have had no problems since.

It all depends on the temperature of the room you are working in and the surface area you are covering. I have found that 24 hours is typically enough time before applying a second coat. For a full cure time I usually wait 3 days.
