Also, that the acrylic products are evenly brushed layers. For these purposes it is important that each layer be clear and touch dry before additional sizing coats are applied. To allow the sizing layers to form a tight film, we suggest overnight drying before the application of Gesso.

This is important for acrylics because sizing traps water soluble impurities from migrating into further layers including Gesso. As with mediums, Gesso also dries quickly. Allow the first coat of Gesso to dry for at least one hour to be sure it will not lift when the next layers are applied.


The number of Gesso coats is optional for the acrylic painter; however the oil painter may wish to apply 3 or 4 coats, eliminating the need for sizing and avoiding oil strike-through to the canvas. However, allowing the Gesso to dry overnight facilitates drawing, sanding or doing detailed work. Oil painters should wait even longer. Oil paints and oil painting solvents are hydrophobic water-resistant. If too much water remains in the acrylic layers, there may not be optimal adhesion.

Acrylic painters have few guidelines during paint application except ones that impede the work process or begin to lift semi-dried acrylic skins.

Thick paints might feel touch dry in less than an hour but take longer to become solid. Overnight drying reduces the chance of color lifting.

For acrylics and other water-based media, if the painting is composed of thin layers, waiting a day or two before applying the isolation layer, followed by another two days to a week before varnishing, is recommended. If there are thick, impasto areas of acrylic paint, wait a week or two before applying the isolating layer or varnish. Upon drying, inspect the isolation coat and if the sheen is uniformly glossy, move onto varnishing.

If the dried coat is uneven, apply a second isolation coat. Isolation coats should be allowed to dry for a minimum of one day before proceeding to varnish. A longer time frame is acceptable. However, if two weeks or greater has elapsed, we recommend wiping the surface with a soft, lint free damp rag in order to remove any surfactants and assure good adhesion with the varnish layer.

This is because varnishes are resoluble and a more cured varnish layer is slower to reactivate and facilitates an easier secondary application. Spray application allows for faster recoating.Get Directions. A: Answer Most products are ready to go right out of the can with no reduction necessary. Some products can be reduced to some degree. The product's data page will indicate the maximum reduction allowed if any and the correct type of reducer. Please note that reducing a paint product past the recommended levels would produce a solution that may not offer the same performance characteristics as those indicated on the product's data page.

If you use a waterborne product directly over such a surface, it may cause the existing texture to begin to soften and fall off of the surface. Test a fast-drying alkyd primer on the surface. Alkyds have the best chance of not wetting the texture paint. If the alkyd primer does not prevent the softening of the texture, then you may have to consider complete removal of the existing texture and reapplication of a new coat.

Application of a fresh coat by roller may be easiest for most; however, in some cases it may not be possible to roll over texture paint as this, too, could cause it to come off. In such cases, application via airless spray may need to be considered. Test the application method over a small area prior to painting the entire ceiling.

A: Answer If this is a concrete slab on grade, check to ensure that the surface does not have a moisture problem prior to considering an opaque coating. Tape a 2-foot square plastic sheet to the floor use duct tape and tape around the entire perimeter of the plastic sheet. Leave in place on the floor for one or two days. Then, check to see if moisture is present between the floor and the plastic. If moisture is present, painting should not be attempted. If the area is still dry, then the surface can be painted.

It's easy to mess up the paint job by applying fresh paint before the undercoat has completely dried. The brush or roller drags the partially congealed paint across the surface and makes streaks that you may never erase.

Always let the paint dry for the recommended amount of time specified by the manufacturer -- and then some if temperatures are cold or the air is humid.

Using sandpaper on the surface of your painted wall or trim before applying the second coat can help focus on the areas that need attention. Scuff walls with or grit sandpaper, and use a pole sander to avoid having to stand on a ladder. Scuff woodwork and furniture with grit sandpaper. There's no need to use a sanding machine -- a light scuffing by hand, going with the grain of the wood -- will do the job.

Look for drips and ridges left by your paintbrush or roller. Take particular care to flatten this with the sandpaper. For larger drips, it may help to scrape them down with a razor blade to do most of the flattening.

Wipe the surface with a damp rag when complete to remove sanding dust. Because it's usually the last one, the second coat requires special care. Any application mistakes may require another sanding job and an extra coat, which means more time and expense for you. Reduce visible brush strokes and roller marks and create a smoother surface by adding paint conditioner to the final coat. Your paintbrush should have synthetic bristles if you're using latex paint and natural bristles if you're spreading oil-based paint.

Use a brush with a clean edge and no loose bristles that can fall out and get stuck in the finish. Use the same roller cover that you used for the first coat, but instead of cleaning it off between coats, store it in a plastic bag so it's preloaded with paint and ready to use.

Don't load the wall, woodwork or furniture with a heavy topcoat. The paint takes longer to dry, and it collects dirt while it's tacky, not to mention that it has more time to drip and separate. Use just enough paint to get full coverage. When rolling, always overlap the previous stroke by half, and roll the entire wall from top to bottom or from left to right in a single stroke.

Stopping in the middle of a stroke and trying to save paint with narrow overlaps create streaks that may take an extra coat to correct. When brushing, always stroke toward the wet edge of the previous stroke, and keep all stroke lines parallel.

There are three distinct time frames to be aware of when it comes to interior painting with water-based known as latex or oil-based known as alkyd or solvent-based paint:. You don't have to be concerned about a paint's cure time when it comes to recoating.

Stay within the following margins of dry and recoat times for both water-based and oil-based paints for a smooth, flawless finish on your interior walls, trim, and cabinetry. Water-based paints always will dry considerably faster than oil-based paints. That's because the water in latex paints evaporates to let the paint dry, and there's no water in oil-based paints.

Paint has binders in its formulation to help hold the pigment together. Flat paints have the least amount of binders and glossy paints both water- and oil-based have the most amount of binders.

The binders in the formulations translate into drying time. The flatter the paint sheenthe faster it will dry. Glossy paints take the longest amount of time to dry. Eggshell and semi-gloss paints, being in the middle of the paint sheen scale, represent average paint drying times. If you're using oil-based paint on indoor trim, doors, and cabinets, the recoat time differs from water-based paint.

Oil-based paint is more durable and takes longer to dry than water-based paint. Oil-based paint may feel dry two to four hours after it's applied. But recoat a full 24 hours after you've painted to make sure the surface is completely dry and ready for another round of paint. Even if you're painting indoors, the temperature of the room and the surface you're painting affect drying and recoat times. Always apply paint within the temperature parameters specified by the paint manufacturer.

Here are a few tips to follow to hasten drying time :. Oil-based paint oxidizes and hardens, which differs from water-based paint that dries via water evaporation. To accelerate the hardening process of oil-based paint, add a siccative, an oil-drying agent containing linseed oils and alkyd resins.

Japan drier is the generic term for these types of catalysts. Whether spray, roller, or brush, the mode of paint delivery affects drying time between coats. Spray paint applies thin and evenly which makes it dry to the touch in as little as 30 minutes and ready for another coat in as little as one hour—even for glossy paint.

Rolled-on and brushed-on paint goes on heavier than spray paint and takes the longest amount of time to dry between coats. Always wait for the full drying and recoat times before applying the next coat.
