   Opt for a caustic stripper to remove primer from concrete or brick. Caustic stripper is a thick, gum-similar substance that contains lye. A caustic stripper volition not remove primer from plastic and it may be alright with forest, but it is perfect for masonry.^[1] Selection up a caustic stripper if you want to strip a brick wall, make clean up a primer spill on physical, or strip paint off of a driveway or sidewalk.^[2]

   • You must neutralize caustic strippers after you've used them, and then choice upwardly enough of white vinegar alee of time if yous're stripping a larger area.
   • Popular caustic strippers include Betco'southward Extreme, Bolt Ultra Full-bodied, and Fiberlock's NexStrip. This stuff normally comes in a plastic bucket.

   Tip: The only divergence betwixt paint and primer is that primer seals a surface while paint doesn't. From a removal perspective, this isn't important. The chemicals that strip paint will also strip primer.^[iii]

2. ii

   Choose a biochemical paint stripper to clean primer off of wood. Biochemical stripper is the safest option available since it uses constitute-based ingredients to erode pigment or primer. This makes it the safest option for wood, just it may not be strong enough for metal, concrete, or stronger surfaces.^[4]

   • This type of stripper is the least likely to damage your surface. If y'all have primer on a model airplane, piece of art, or some other frail surface, try using a biochemical stripper first.
   • Citri-Strip is probably the near pop biochemical pigment stripper, simply SmartStrip and Franmar are great options as well. These strippers often come in plastic containers that resemble laundry detergent or insecticide.

3. three

   Get heavy-duty solvent for metal, plastic, or to take stubborn primer off. If the primer is particularly thick, one-time, or you lot have primer on a metal or plastic surface, get a heavy-duty pigment stripper. Heavy-duty paint stripper is extremely potent, only it'll get primer off of basically whatever surface. Keep in mind, this stuff is actually toxic and so you shouldn't apply it unless you accept to.^[five]

   • Heavy-duty solvent will also work on wood or masonry, but this is overkill.
   • When it comes to pigment strippers, heavy-duty is typically code for high-VOC. VOCs, or volatile organic compounds, are pretty toxic so work in a well-ventilated area and put on safety gear when using this kind of stripper.
   • Heavy-duty solvents include Dumond'southward Skin-Abroad, Old Masters, and Klean-Strip, which is probably the most popular choice. These solvents usually come in an aluminum can.

If you're stripping forest, apply information technology in the direction of the grain. Otherwise, go back and forth in any management to cover the surface.^[7]

   • Most stripping agents are pretty thick. Yous may need to reload your brush every iv-5 strokes to keep it from drying out.

3. three

   Build up a ¹⁄_viii – ¹⁄₂  in (0.32–1.27 cm) layer of stripping agent on the primer. Reload your castor as needed and continue spreading the stripping over the surface. Cover every crack, textured surface, or gap in the material to completely cover the primer. Continue spreading the stripper around until you build up a layer of stripper on the surface.^[viii]

   • Heavy-duty solvents typically require thin layers. You won't demand to build up more than a ^one⁄₈  in (0.32 cm) layer of stripper on the surface for this amanuensis to exist constructive.
   • Caustic and biochemical strippers ofttimes need to be congenital up in a thicker layer. Read the label to see how thick of a layer you need. Often, you lot'll need a ¹⁄₂  in (1.3 cm) layer of stripper to remove primer.

4. 4

   Lay plastic sheeting over the surface if information technology came with your stripping agent. Some caustic strippers and a few heavy-duty strippers need to be covered with plastic sheets to piece of work the stripper into the material. If your stripping agent came in a kit with plastic sheets, you must use them. To apply these sheets, spread your first canvass out past hand and printing it against the surface you're stripping. Smooth information technology out with your palms and press out any air bubbles. The plastic sheeting volition automatically adhere to the surface.^[9]

   • These sheets force the stripper into pores in the surface material. This is specially important if you're removing primer from brick.

5. 5

   Wait 30 minutes to 12 hours for the stripper to soak into the primer. The soaking time is listed on your container, and then read the label thoroughly to make sure you don't miss annihilation.^[ten] Typically, the stronger the stripping agent, the less time it needs to soak. Wait 30 minutes to 12 hours depending on what the label says to requite the stripping agent time to eat away the primer.^[eleven]

   • You won't meet the primer falling off of the surface or anything. All the stripper does is weaken the primer to make information technology easier to remove.

   Employ a pigment scraper, putty pocketknife, or razor blade to scrape the primer off. Put all of your protective gear back on. Take hold of a putty knife or paint scraper if you're removing the stripper from wood or masonry. Opt for a razor blade to pare the stripper off of metal or plastic. Elevate the blade of your scraping tool at a fifteen- to 25-degree angle to the surface to peel the stripper and primer off.^[12] Work in vertical or horizontal strips to remove the layers of stripping agent and primer. Proceed doing this until the primer and stale out stripping agent is completely gone.^[13]

   • The stripper will have hardened, so you can work in whatever guild you'd like. You can peel the primer off in vertical or horizontal strips, or work in 2–iii foursquare feet (0.19–0.28 m^two) sections until the surface is entirely clean.
   • You may demand to use a wire brush after you scrape porous surfaces, like brick or physical.
   • This can accept a while if you're removing primer from a larger surface expanse. Unfortunately, at that place aren't whatsoever easier ways to exercise this.

2. two

   Neutralize the surface in water and vinegar if required by the stripper. Read the label of your stripping agent to see if you need to neutralize the surface when y'all're done. If y'all practice, fill a spray bottle with 1-function white vinegar and 1-function tap h2o. Thoroughly spray the surface area with your vinegar mixture to neutralize the acid from the paint stripper. Let the vinegar soak for a minute or ii while you lot get a testing strip out.^[14]

   • If you take a smaller object, y'all can soak it in the vinegar solution for 3-5 minutes if you adopt.
   • Well-nigh heavy-duty and caustic stripping agents need to exist neutralized. Most biochemical strippers practice not.
   • You cannot neutralize the paint stripper with water lone. This will only spread the acidic agent around on the surface.^[15]

3. 3

   Test the surface with a pH testing strip if you neutralized it. Go a pH testing strip and lay it down on a damp portion of the surface you lot stripped. Allow the liquid soak into the strip and wait for the strip to change colors. Use the color-coded reference chart to assess what the pH of your surface is. If information technology's at, or relatively close to, vii pH, you lot're done. If the acidity is still too high, mist, wash, or soak the surface in more water and white vinegar before testing it again.^[sixteen]

   • Any reading lower than a 6.five pH is considered too acidic. If the surface has an acidic pH, it means that the stripping agent left a residue behind. Your surface may weaken or discolor over fourth dimension and you may get acidic residuum on your hands if you lot touch the surface.

   Warning: If yous do not neutralize the stripper, the residual acrid volition wear away the surface you removed the primer from and damage information technology over time. You may also stop up with pocket-sized particles of the stripping agent on your skin the adjacent fourth dimension yous bear upon the surface, which may crusade a chemic burn.

4. 4

   Clean the surface in water or mineral spirits if you didn't neutralize it. If your stripper's container doesn't mention anything well-nigh neutralizing it, read the label to run into if you lot need to wash the surface with mineral spirits. If you do, pick up some mineral spirits and rinse the surface with them. Otherwise, use regular tap water to rinse the area. But hose down the surface or pour water over the textile to launder off the remaining stripping agent.^[17]

   • This is an important safe measure. If yous don't neutralize the surface, y'all must wash information technology off. If y'all skip this step, you could terminate upwards called-for your skin the side by side time yous bear upon the surface.
   • Be conscientious if you're working with mineral spirits. Wear protective eyewear and a dust mask. If you get any spirits on your hands, launder them thoroughly with soap and water.^[xviii]

5. 5

   Let the surface air out until information technology'due south completely dry. The corporeality of time it takes for the surface to dry depends on the material. Metallic and plastic willy typically dry pretty apace, but forest and masonry may take up to 24 hours. But wait until the surface is completely dry before touching it or doing anything else.^[19]

  Mapei primer is a low-voc water-based primer. It isn't specially strong, so it shouldn't be too hard to remove. Pick up a heavy-duty pigment stripping solvent and use a disposable brush to cover the primer in your stripping agent. Read the label on the solvent to encounter how long it needs to soak and then apply a putty pocketknife to scrape the stripper off. The primer should peel right off of the door.
