You can take some denatured alcohol or fingernail polish on a cloth and lightly rub it on an inconspicuous test area. If the paint softens and is easily removed, then it is a latex paint. If the paint does not really seem to be affected by the test, it is typically an alkyd coating.
No. These types of products do not actually have primer mixed into them. The “Paint and Primer” products use quality resins that allow for good adhesion. This helps to eliminate the use of primers in most circumstances. Please note that primers may be needed in special cases. Contact us at Douglas & Son (269-344-2860) for more information in those instances.
In general, flat and low sheen paints do not have a high amount of scrubbability. Areas that experience higher traffic or those that are washed should be painted with a higher sheen product. At minimum, a “satin” type or higher sheen is usually recommended in those areas for their overall durability.
In most cases and with the latex technology used today, this should not be an issue. The surface to be painted needs extra attention in preparation to be repainted. WARNING! If you scrape sand, or remove old paint, you may release lead dust or fumes. LEAD IS TOXIC. EXPOSURE TO LEAD DUST OR FUMES CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD AVOID EXPOSURE. Wear a properly fitted NIOSH-approved respirator and prevent skin contact to control lead exposure. Clean up carefully with a HEPA vaccum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the USEPA National Lead Information Hotline at 1-800-424-LEAD or log on to www.epa.gov/lead. Follow these instructions to control exposure to other hazardous substances that may be released during surface preparation.
Depending on color choice, atmospheric conditions and other variables, latex paint may take up to 60 days for a full cure. In most cases, latex paint can be put to normal use after a day or two. Fresh latex should be allowed to cure for at least 14 days before attempting to wipe or wash the walls. It can be sensitive to water or chemicals during the curing process. Also see the previous question regarding sheen choice. Lower sheens will be more susceptible to moisture and chemicals, even when fully cured.
No. Primers are not always needed when repainting. If you are repainting a similar color, you can lightly scuff or sand to remove the gloss and clean the surface. Once that is completed, you can simply repaint over the existing latex coating. More than one coat may be needed for uniformity. Please note that switching sheens or drastic color changes may require a primer to minimize the amount of topcoats used. WARNING!

Masking tape or even “painter's tape” may tend to stick to fresh coatings if not removed shortly after painting or pulled improperly from the surface. When the paint is applied to the walls, it will inevitably cover over the tape as well. As the paint starts to dry, it will start to adhere to the wall as well as the tape. This “bridge” of paint from the walls to the tape will lift as the tape is removed. To help minimize this issue, you can lightly “score” the edge of the tape with a sharp razor or utility knife. This will help break the “bridge” or “film” between the painted wall and tape. Also, try to pull the tape staying close to the wall but pull away from the painted edge.
There are several reasons why paint will not cover in one coat. Some of the main reasons include drastic color changes, i.e. light to dark color or even dark to light color, thinning the product, stretching the product near or beyond its coverage rate, or improper roller cover used.
The coverage rates on the container are based off of a theoretical calculation. This calculation does not account for any loss due to product left in the container, roller covers, brushes, or variations in the surface that it is applied to. Depending on the aforementioned variables as well as overall surface porosity, you may see a lesser spread rate than what the “theoretical” coverage rate is on the container.
Lap marks are created when a wet edge is not maintained while painting. It can also be caused when the paint is applied in a vertical motion only. Make sure to keep a wet edge as well as spread the paint in a “W” or “M” pattern on the wall. This will help spread the coating and create an even film on the surface. Once this is done, you can go right back over that area and roll from top to bottom to minimize a “shadowing” effect in the dried film.
Historically, vinyl siding could only be painted the same color or lighter as the siding would warp or buckle when painted a color darker than the original siding. This was because traditional darker colors caused the siding to warp when exposed to sun and heat. Now, however, we offer SidingSafe® Color Technology, a method the PPG Color Laboratories created of developing color formulas specifically for these substrates, eliminating the worry of warping or buckling. Choose from our SidingSafe palette of more than 80 beautiful shades, nearly all of the 1,900+ colors available in The Voice of Color®, or pick your own and ask your PPG representative to help match virtually any color.
