How do I store paint without it drying out?
Question:I am decorating, but sometimes use paint only once or twice a week. When I open the tin, I often find a film formed on top, which makes the paint lumpy. How do I prevent this??
Also. what is the best way to clean brushes really well? Mine seem to end up with all bits in them, which come out when I next paint.
Answers:
Most paints react with oxygen to skin and eventually dry up. So you can prevent that from happening in a less-than-full paint can by adding an inert, heavier than air gas to the can to prevent oxygen in the air from reaching the paint. A prefect seal, made with films or anything else, won't prevent than from happening if there's a lot of air (and therefore oxygen) in the can for the paint to react with.
You can buy commercial products, but I recently came across a quick and inexpensive way to do the same thing using items that you probably have around the house.
In clean half-gallon pitcher, put a teaspoon of baking soda. Then pour in a 1/4 cup of vinegar. Swirl the mixture to mix it - you don't need to mix with a utensil. The reaction makes CO2, an inert, heavier-than-air gas. As the reaction slows, you can pour the gas (not the sludge at the bottom) off into the can before quickly sealing it shut.
good luck-
Put the lid on tight and store it upside down. Brushes are so cheap now throw them away after use then use a new one.
Make sure that you put the lid on properly. When you open it give it a good stir.
Try put clingfilm over the top & then put lid on firmly. You will still have to break a top layer of dry paint
I would store it in a cool area w/ the lid on tight and store upside down (not freezing)
Home Depot sells empty paint cans, in different sizes. When you have used 2/3 or more of a can, pour the remainder into a new smaller can so there is no air in the can. Dab a bit of paint on the cover so you know what's inside.
Clean brushes: soak them a while before cleaning them and rinse them under the force of a garden hose.
I clean up after painting outside: don't like all that paint going down the drain--even if they say it's ok.
when you put the lid back on turn the tin of paint upside down and this will stop it forming a skin on the top
You can take a piece of plastic film and lay it on the surface of the paint. Cleaning brushes depends on what kind of pint you are using. For latex or oil, however, you should get as much of the paint out of the brush before you start to clean it. Do this by brushing on a piece of scrap or cardboard until no more paint comes out of the brush. Clean the rest of the latex paint from the brush with hat, soapy water. Clean any dry paint from th bristles using a stiff brush and stroking towards the tips of the bristles. Clean oil based paint using solvent. You can re-use the solvent by letting the pigment settle to th bottom of the solvent and pouring off the clean solvent from the cleaning can. Brushes used for oil based paint can also be suspended in the solvent for keeping or you can wrap them in plastic film. The next time you use the brush, use the same technique that you used to get the excess paint out of the brush and brush on a piece of scrap until the brush is dry. The plastic film wrap will also keep the brushes for a few hours if you get interrupted.
When you are using oil based paints like gloss you need to replace the lid firmly and shake the can before storing it upside down! If a film then forms it's on the bottom of the paint! Emulsion paint should always be thoroughly mixed preferably with a mixer designed to fit on a drill. A good alternative is to make your own using a metal whisk!
Brushes should be thouroughly cleaned in white spirit or brush cleaner and then washed in very hot soapy water and given a final rinse in cold water before being dried hanging up with the bristles downwards.
Store it upside down. Also don't use cheep brushes. Use good quality brushes and clean them well after. If you use a cheep brush, that's the finished look you'll get. To clean a good brush,for water base paint,Rinse the paint out with warm water,never cold,never hot. run a scraper in between the bristles up to the nub,and work the paint out. If it's dried, you can get ,"Rid a Brush"made by the Red Devil company. If you don't have that, a little Easy-Off oven cleaner will take it off. Use the one in the blue can,or the fume-less. For oil based paint, the same thing but use paint thinner. Never let your brushes sit in a jar with the tips touching the bottom. If you need to soak them, tie them to a string,and let them float in the solution. After rinsing,in warm water, let them air dry upside down. Alot of work,but worth the finished look. Bye
Storing the paint is easy: make sure the lid is very secure and tight on the can, then store the paint upside down. You can give the can a good shake before you open it again to re-mix it.
As for cleaning the brushes: here's a tip I picked up working in a theatre. If you're going to be using the brush again in the fairly near future, load the brush well with paint and wrap it with plenty of plastic wrap. (I use a plastic grocery bag, then put that in a ziplock bag, but that might be overkill.) The plastic wrapper keeps the paint from drying out and saves the time of cleaning brushes every time.
When it is time to clean the brushes, remember to take your time and be thorough. For water-based paint, turn on the water faucet and let the water run over brush from the base of the bristles toward the tips. Work the bristles with your fingers gently, to expose all the bristles to the water. It can take a while for all the paint to rinse out, so be patient. When the water finally rinses clean, shake out as much excess water you can, then shape the bristles with your hand to their proper positions and put the brush where it can dry bristles-up.
For oil-base paints: put the brush in a disposable can or jar. Add enough paint thinner to cover the bristles and swish the bristles around until the thinner is thoroughly saturated, then dispose of the thinner and replace with fresh. Repeat until the brush is clean, then re-shape the bristles and set aside to dry, bristles up. Again, patience is the key.
Or you can but cheap brushes and throw them away when you're done. ;-)
No matter what you do you will still get a skin on the top of the paint even if it's upside down, the skin will still be there and stirring it will cause lumps, what I do is to carefully go around the edge of the skin with a thin kitchen knife and lift the skin off, with a bit of care you will be able to remove all the skin. Been doing this for years and it works fine. Some paints are water based, some are spirit based, so use the correct solvent to remove as much as possible and then rinse throughly in washing up liquid with hot water and leave to dry bristles down-wards.
Rather than spend money buying paint cans and pouring the paint into increasingly smaller tins, just fill up a plastic bag or balloon with water and seal it tight, then put that into the paint tin, increasing the volume in it so that there is less air in the tin.
If the intervals between painting is not too long, wrap your paintbrushes in newspaper and submerge them in a tin filled with water. If you use the same brush for a different colour, then clean it when you want to use it. Normally wouldn't have a problem cleaning paint brushes if its water based paint.
I would use an old or cheap tupperware container. You are probably getting a bad seal when you put the lid back on because of dried paint in the dip where the lid is hammered into. Using a plastic container will also work nicely for storage but remember to label it date-color-sheen-room location that is the important info. and remember paint is only good for 4-5 years. As for your brush situation I would use a wire brush brushing only in the direction of handle to bristle tips. Good luck:)
Store upside down.
If you have 'solid' brushes, these can be recycled by putting bristles in paintstripper, then working the brush. To rmove most of the waste, use a wire brush on the bristles. Then, clean with paint brush restorer / soap and water. I always clean my brushes in paint brush restorer after use, that way i have a nice clean & dry brush for the following job. You get what you pay for with paintbrushes, I have some very old but still good, brushes. The bonus is, unlike humans who go bald...a well used brush rarely drops a hair.
this works,put lid on tight take a hammer and dent the side of the can,garenteed not to skin up,not alot of people know that.
ensure the lid has no paint on the seal and put a piece of clingfilm on the paint surface in the tin. works a treat for years.
Make sure lid is on firmly, dont store in sun put in garage. If it is a gloss brush leave it in a container of water, emulsion brushes can be left in plastic bag/ cling film until ready to use again. Our gloss brushes are stored in water in an old paint tin. The emulsion brushes obviously get washed out if we use different colour paints
well for a start remove the skin if it happens again!! soak the brushes over night in a cleaning solution, white spirit then wipe them thoroughly before use you could then wash them in a mixture of washing up liquid and water but would make sure they were dry before using them with gloss paint
