Yep! It’s that good
If you have not already, its time to consider DRC’s as a new option with unmatched performance, reliability and effectiveness over bare drywall or problem surfaces. No wall primer offers the capability of Drywall Repair Clears today.
Zinsser prides itself on being painter-friendly by offering a wide range of niche product you can apply with confidence. So it’s not surprising Zinsser GARDZ® takes sealing to the next level with a slew of features.
GARDZ Problem Surface Sealer is a unique water-base sealer for porous and potential problem surfaces. It is formulated to deeply penetrate and dry to a hard, moisture resistant film that seals and binds down porous, chalky and crumbling surfaces, paints and texture finishes.
GARDZ is recommended for: damaged drywall, new drywall, spackling and joint compound skim coats, plaster, calcimine, uncoated wallpaper, wallcovering adhesive residue, texture paint, popcorn ceilings and over builder’s flat paint.
HOW WE USE GARDZ
With a similar cost comparable to less effective wall primers, GARDZ saves us countless labor hours and material costs.
- GARDZ provides a moisture resistant coating, therefore paint spreads at higher rates.
- Provides a hard non-porous surface in a single coat. No need to constantly re-coat ceilings or walls to achieve full sheen or solid coverage over drywall mud.
- We use it to effectively equalize the porosity between drywall board and the various mud types used.
- Provides great adhesion to bare drywall where wall primers rarely hold up to a simple tape test. If your drywall primer doesnt stick to the drywall like this photo below — how will your paint stick?
- Apply GARDZ to stripped wallpaper and cleaned walls to ensure any glue residue is locked down and will not surprise you after your first coat of paint is applied. Have you ever stripped wallpaper, cleaned thoroughly (at least you thought so) and painted only to see glue spots come through the finish? We have, and it is backtracking to fix, lost money.
- We use GARDZ on new drywall and the patches made instead of a wall primer as the undercoat for washable flat, satin and eggshell paints.
- Apply GARDZ to ripped and torn drywall prior to mudding or skim coating for repairs then reapply to your new mud.
- Stop chasing flashing caused by drywall patching. A MUST READ if you are considering GARDZ.
HOW TO APPLY GARDZ
The product is clear and water-like. It reminds me of waterborne clears but thinner, similar odor.
- Microfiber type covers work great. Apply the first load on the wall in an upward motion with light pressure.
- A 100% nylon brush works best just like spreading waterborne clear coats,
- Apply with a 100% nylon brush or microfiber cover. The product levels out and pulls tight. Brush strokes disappear.
- Generally there is no need to sand a sealed patch area prior to painting
- You may want to use a wall primer or a coat of finish paint over GARDZ in some situations prior to the final coat.
- ALWAYS TEST AN AREA FIRST. Some finish paints are known to dry shiner over the areas sealed with GARDZ especially if GARDZ was not applied as the base coat.
- It is best practice to have GARDZ applied as the undercoat for the entire surface prior to painting or patching. This way, everything is treated as equal because GARDZ does such a good job at sealing.
Take a close look at the photo below. I want you to understand what you are looking at. This is two coats of Sherwin Williams Duration Satin applied over two coats of wallprimer. A patch was made and sealed with GARDZ. I took a brush and painted over the small patch rather than the entire sealed area. You can see a dull spot in the center of the shiny area. That is the area I applied paint with a brush before rolling a final coat over the room. This is a non-issue with some other paints.
- Can be applied traditionally with brush and roller or a pump-up tank sprayer. Be sure to protect yourself and eyes.
SPRAYING CEILINGS AND WALLS
- I prefer to spray and backroll over bare drywall to work the sealer into porous mud.
