What Is Oil-Based Paint?
Oil-based paint contains natural (linseed) or synthetic (alkyd) oil as a base. Due to lower price and higher strength of alkyd it has become more common. However, both types are tough and durable, making them good choices for exterior house painting jobs, interior doors, bathroom or kitchen cabinets, and trim. As oil-based paint cohere well to the surfaces it will protect metal fences from the elements. Oil-based paint works well for painting metal. Oil-based wood stains are another product in which the oil base is actually beneficial for the wood.
|Oil-based paint is durable and more resistant for low temperatures than latex.||It’s very hard to clean up after painting. It also needs a solvent for thinning paint during use.|
|Oil-based application is smooth and provides great coverage.||Takes long time to dry, so you might not be able to apply a second coat that same day.|
|These oil-based paint can be applied to stained, chalky or dirty surfaces.||Without first applying primer should not be used to untreated masonry or drywall.|
|Oil-based paint is better at covering small imperfections or slightly damaged areas.||Can’t be touched up in small areas without causing noticeable marks.|
|Walls when painted with oil-based should be scrubbed hard.||Contains high VOC(Volatile Organic Compound) levels|
|Oil-based paint is much richer than water-based paint.||Oil-based must be treated as hazardous waste for disposal.|
Can You Paint Over Oil-Based Paint?
Latex paint (and even other oil-based paint) can be successfully applied over older oil-based paint as long as the surface is fully cured and there is nothing inherent in the coating that prevents another layer of paint to be added. Preparation of oil-based is important. When the surfaces is glossy it doesn’t need a second layer of paint, they just need proper cleaning and priming. By following this steps you can achieve.
Equipment / Tools:
- High-quality paintbrush
- Fine 180-grit to 220-grit sandpaper
- Medium 100-grit to 150-grit sandpaper (optional)
- Putty knife or five-in-one tool
- Tack cloth
- Wood putty or wood filler
- TSP (trisodium phosphate)
- Paint primer
- Soft sponge (for TSP)
- Protective glasses
- Protective gloves
Instructions You Need To Paint Over Oil-Based Paint
01 De-Gloss the Surface
Scuff down the surface of the oil-based paint layer by using sandpaper for improved stick ability. Look to eliminate surface sheen or gloss, don’t remove all the paint, all you need to do is just scuff up the surface. By doing this new primer and paint will absolute well for the surfaces. Use fine-grit sandpaper for priming when it is not working well, then you can switch to gentle scuffing with medium-grit sandpaper.
02 Remove Chips
With the help of five-in-one tool or putty knife remove the loose paint from your walls.
03 Fill In Small Gaps and Holes
By using wood putty or wood filler fill small gaps and holes. After filling gaps and holes leave them dry completely, then lightly sand the filled ares by using fine-grit sandpaper.
04 Clean With a Tack Cloth
After all these steps followed know with the help of tack cloth wipe down the surface to remove the dust particles, dirt which is present in the surfaces. You should do this process after the surface dries completely.
Tack cloth is an inexpensive, simple product made of cheesecloth impregnated with beeswax. Its sticky surface takes up stray dust particles. Use gently; applying hard pressure will result in a waxy surface which can be hard to remove.
05 Deep Clean The Surface
Even after using a tack cloth if the surface is still oddly dirty and greasy, we recommend you to use TSP to do a deep cleaning before priming. Mix 1/4 cup to 1/2 cup (for extra dirty surfaces) TSP with a gallon of hot water. To wash the surfaces use a sponge that’s moist with TSP solution. To bring down streaking wash the surfaces from the bottom. After cleaning with TSP, sponge the surface with fresh water to rinse (unless you have chosen a no-rinse TSP formula). Let the surface thoroughly air-dry.
TSP(trisodium phosphate) is a harsh but effective cleaning chemical used to prepare walls and other surfaces for paint. It also acts as a de-glosser. Make sure you have adequate ventilation, skin, and eye protection before using TSP.
06 Prime The Surface
When the surface is fully dry and clean of dirt, then you need to start prime it. This is very important as it prevents the latex paint from peeling. Use at least one coat primer onto the surface. Let it dry completely!
07 Paint The Surface
The last and very exciting step is to paint the surface. Get ready to paint the surface after the paint dries completely. If it’s necessary use two coats of paint. Let it dry for at least 2 hours.
For the best painting technique, do not load up the brush with too much paint; only dip the tip of the bristles into the paint. Draw the paint in slow, even strokes, always maintaining a wet edge.
