I purchased this after reading How To Paint Furniture on the JustAGirl blog. That chick really knows her stuff. I was repainting my bathroom cabinets in lieu of ripping it out and replacing it. I wanted it to look GOOD. This stuff did the trick plus I used Benjamin Moore Super Spec paint which is highly washable which I needed in a bathroom. It’s kind of thick once you stir it up but dries fairly quick. I don’t know what else to say other than my paint laid very nicely over it. Even my hypercritical father was impressed. I plan on using this for some older furniture I want to revamp and possibly my kitchen cabinets!

I love this paint. I’ve used it in the bathroom and on cabinets and doors. Its amazing. Its so refreshing to use this because everything looks so white and clean now. No stains have seeped through in the bathroom and I’ve had it on there for about two weeks. The smell isn’t too strong it is very tolerable. And if you drip it anywhere or get it on your hands(or face and legs and arms and feet like I did lol) its easy to get off! Also I used two coats.

Tamara Thorne said

We’re doing a home renovation and KILZ Klear stain-blocking sealer has come in very handy. The walls in our sixty-five-year-old home are plaster and not a problem, except where we had some water damage. We re-plastered the section of wall – about six-feet by three-feet and it needed sealing before we could paint. We used the Klear sealant. It completely stopped the plaster from rubbing off on our hands and the paint took to that part of the wall just as it did the untreated plaster. We were afraid it might show, but it didn’t. Not one bit.

We removed an old wall heater in another room and used drywall and plaster there. We applied Klear to that before priming and painting (with KILZ Tribute paint with primer in it) and it came out perfectly. (We used two coats and you only have to wait half an hour between them – Klear dries very quickly.

Finally, we built a small brick wall edging the walkway to our house. We used Klear before painting and the bricks didn’t suck in paint like they normally would. We’re really impressed. This is a great product!

This stuff is AMAZING. When researching how to repaint my dated cabinets, I came across a professional cabinet painter who recommended this stuff. He said the other formulas aren’t so reliable, but this shellac-based primer will basically allow any paint to stick to your project. I’ve used it on cabinets, base boards, and ceilings. This primer dries quickly and yields consistent results.

Mel M said

I’m a beginner when it comes to doing anything “handy” and that includes refinishing furniture. But after seeing so many fun ideas on Pinterest, I decided to take on redoing a cedar chest. My goal was to paint it blue, so I wanted to start with a good primer. I read a lot of positive reviews on this product and figured I’d give it a shot. I love it! The trick I learned was a couple of thin coats works best. I also gave it a light sand afterward which made it super smooth. It adhered to the chest (I had lightly sanded the chest prior to applying this). The paint rolled over this nicely and all in all, I’m very happy with the result. Looking forward to my next project with cover stain!

How to Choose and Use Primer: Drywall & Paint

choose best bathroom painting tools including primer

 Interior stains and odors

 Interior stains and odors

A few stains will bleed well through most primers and paints regardless of what number of coats you apply. The equivalent goes for serious scents like smoke from flames and cigarettes. The solution to this is to use a primer that blocks stains. Oil-based primers need a paint thinner for cleanup because they emit a bad smell but they are best for blocking water-based odours.

Water-based primers are simple to clean and have less odour. These features make water-based primers ideal for blocking solvent-based stains.

New interior bare wood

To hide imperfections and make wood surfaces more uniform it is necessary to prime wood. Oil-based primers that dry slowly like enamel undercoat primers are easier to sand and offer good adhesion than water-based primers. Using a water-based primer will raise the grain of the wood and you will be required to sand thoroughly before applying the topcoat.

MDF (medium-density fiberboard)

Unless the MDF is pre-primed use an oil-based primer. Using a water-based primer will soak the board and make it swell. Before applying your oil-based primer make sure you sand the board surface to make it smooth. Don’t forget to keep it dust-free also. After that, you can prime all the surfaces not forgetting the edges.

Exterior woods that stain

Woods that have tannins like redwood and cedar will bleed through an ordinary paint or primer. To avoid bleeding utilize an exterior oil-based primer. For large areas use exterior paint primer together with latex finish. Use only an oil-based primer if you are going to use an oil topcoat.

Exterior Wood

Outside paint gets beat. What’s more, perhaps the most ideal approach to prolong the life of your paintwork is with a decent primer. So except if you appreciate scratching paint, spend about $30 per gallon on a top-quality acrylic/latex outside primer. Search for “100 percent acrylic” on the mark, and ensure the wood surface is perfect, dry and dull (no sheen). On appropriately arranged dividers, an excellent groundwork can twofold the life of your outside paintwork.

Best Primer for Bathroom: FAQs

Do you need a special primer for a bathroom?

Your bathroom walls require more than a primer. You will need a primer that is more formulated to seal and stick a surface more perfectly. The primer you choose should be able to mask the existing colors and cover stains.

Do I need to prime bathroom walls before painting?

If the walls have been previously painted there is no need. But bathroom walls that have been exposed to humidity well require you to prime even though some specific primers have been made with biocide which will help eliminate odors and mildew.

What kind of primer do you use in a bathroom?

Use a stain-blocking primer for places with high humidity to prevent peeling off and mildew. Places with high moisture peel off easily and exterior walls can blister.
