Product Information

Using a Spray-on Lacquer: Clear or colored spray lacquer can be used as a primer over MDF with good results. Use one designed for exterior finishes. Some lacquers create very smooth coatings which inexpensive craft paints will not adhere well to. If you use these liquid acrylics for painting your miniature projects, test them over the lacquer to make sure they adhere well before you use them to topcoat the lacquer primer. Take care to follow instructions when working with lacquer primers. Avoid all heat sources and work in a well-ventilated area. You can use both oil-based paint and water-based paint on MDF. In general, while oil-based paint has traditionally been higher quality than water-based paint, todays technology means that water-based paint is just as good. You must wear the appropriate safety gear as MDF causes a large amount of dust when sanding and sawing For those concerned about toxicity and VOCs (volatile organic compounds) in traditional paints, milk paint and chalk paint offer non-toxic options suitable for MDF. Milk Paint

For arts and crafts, there are no specific paint product recommendations, opt for flexible acrylics over oil-based paints. Oil-based paints can cause MDF swelling and damage. Instead, choose water-based acrylics that remain elastic when dry. Oil-based paints are a more traditional option, they can have higher levels of volatile organic compound (VOC) emissions during application and drying, which can have a negative effect on the environment. Cleaning oil-based paint is also difficult and requires the use of harsh chemicals. It can also take longer to dry than water-based paint. Advantages of oil-based paint Firstly, if the MDF has dirt or grime on it, this must cleaned before we begin priming and painting. A universal cleaner such as Zinsser Universal Degreaser & Cleaner can be used, which is then wiped down with a cloth ensuring that no residue is left. Seal the MDF with PVA Glue: You can seal MDF surfaces with thin layers of PVA (white or carpenter's) glue. Most PVA-based carpentry glues require dilution with water to get a thin sealing layer on your MDF (which can cause the MDF to swell). Thin, acid neutral PVA glues designed for paper and bookbinding work well if applied with a roller, spreader or spray bottle designed to work with thinner glues. Some brands of PVA as a primer may continue to be slightly 'rubbery' under paint coatings and will not withstand wear as well as paint applied over solvent based primers.The big issue with MDF is the edges, these are more porous than the top/bottom of the board and need more attention. To get a really smooth non-porous finish on the edges you can use wood filler or MDF edging tape. If the edges aren’t going to be seen simply add an extra coat of sealer/primer and rub down.

Once the MDF has had a light sand, you can apply a second coat of primer as evenly as possible, creating a final base that is ready to be painted. While this seems like a long-winded process, the preparation that goes into painting is what sets apart good results and perfect results.
