Common Problems and Their Causes with Kilz 2 Primer

We’ve covered the most common problems and causes faced with Kilz 2 Primer.

Peeling/Streaking from Dry Wall

Peeling and streaking happen when the wall isn’t cleaned. Having debris, oil, and chipped old paint can cause the primer to form clumps and peel.

If there’s excess oil on the surface, it may cause the primer to streak down. Another cause for primer peeling is recoating before the first coat has dried.

It may also cause bubbling.

Also, it’s better to know if you should first caulk or grout before priming specific surfaces.

Paint Not Sticking to Primer

Priming the walls will not ensure a proper paint job. You may face paint adhesion problems when – 

  • Walls are dirty
  • If the weather contains too much moisture
  • Running your primer over the same area often
  • Recoating and repainting before letting it dry
  • Chemical formulations of the primer and paint not cooperating

This is also one of the common problems while painting ceilings.

Not Sticking to Wood

Wood surfaces can be of various categories. But common features of a wooden surface hold uneven, rough, and minor textures. 

Also, dust and grains of wood are present if the wood is not sanded and cleaned. 

Due to this variation in texture and evenness of the surface, primers may have a hard time sticking to the wood.

Common at-Home Solution

If you want to get the problem solved yourself we’ve written down 4 easy to follow steps.

Step-1: Clean the Surface

First, take a sponge and warm water to clean your surface properly. If there’s a presence of oil or grimes on the surface, an anti-grease detergent with a water solution should be used for cutting grease.

Next, another wipe with clean water should do the job. 

Also, if mildew is present on walls, that should be cleaned as well. It’s better to know how to prevent mildew from growing. 

The surfaces need to be dry before taking further steps.

Step-2: Sand the Surface

Sanding is crucial for surfaces that are uneven and have been painted before. Especially if the surface had a glossy paint job.

Use sandpaper or sanding blocks to dull out uneven surfaces. For water-based paint, use fine-grit sandpapers. For oil-based paint, use sandpapers with 100 to 150 grit.

For wooden surfaces, you have to use 180 or 220 grit sandpaper.

Make sure no cracking or flaky paint remains on the surface. The best surface is that which doesn’t contain any residue from old paint jobs.

After sanding the surface, clean it with water and a sponge. Let it dry again.

Step-3: Coating Primer on Surface

Primers make your paint jobs look more vibrant and smooth. Imperfections, cracks, and stains can be covered up, giving your paint to sit on an even canvas.

When painting a primer, keep your windows open so that fumes can escape. Primers can be applied with brushes, rollers, and sprayers. 

However, it is best to first brush the areas that a roller can’t reach; before using rollers to fill in. Make sure the whole surface is evenly coated!

Step-4: Curing Before Recoating or Painting

Recoating or painting over wet primer is a recipe for a mess.

It is important to make sure the primer is left alone for drying. Kilz 2 requires 1 hour before getting recoated or painted over.  

For wooden surfaces, sanding and cleaning should be done again after one layer of primer.


Before going to work, you need to take some precautions first. You need to do so to ensure that you don’t run into any problem.

Lead-Based Paint

Avoid scraping or sanding lead-based paint. It is highly toxic. Use a lead testing kit to check for its presence.
