Introduction: Stone Protection

The tough General Chemical’s Peelable coating clear film is still the best method of preventing scratches and abrasions and strips cleanly away from the surface leaving no residue. It will also act as a masking against paint overspray.

Marbleshield 4580 is a water based peelable coating which cures upon water evaporation to a clear water resistant hard film. The cured films can be applied to concrete, marble, sealed wood and most other surfaces that are non porous. The viscosity of this material is high and that helps the film to bridge over minute cracks. The coating can be peeled by prying a corner and lifting the paint off. A gallon of Marbleshield will cover 160 to 190 square feet. Application by airless spray is best but it can also be applied with paint rollers.

Main Advantages

  • Safe to use
  • Water Clear — No Dyes or Pigments
  • Water resistant when dry
  • Water cleanable when wet
  • Peels from variety of surfaces

Customer Comments

“I did purchase the liquid masking coating for marble and stone surfaces. It’s an unusual application I am sure, but we installed a new kitchen back splash with a green/white marble tile and the grout color is a dark green. When testing grout on tile samples I had problems with the marble absorbing the grout into surface of the tile and turning the white marble dark and greenish muddy looking. It was not good. Reading up on tiling I found that natural stones and marbles will absorb grout unless you seal the surface. I tried various tile sealers sold for this purpose and none of them worked well and the tile always ended up dark and blotchy. So, in desperation, I started looking outside the box of traditional tiling methods and was looking for something that I could coat the face of the tile with, grout and then remove again. I came across your liquid masking coatings through an internet search.
To wrap up a long story, the coating works tremendously well. It went on easy with a simple paint roller (a small detail roller with a short nap) and does a great job at minimizing the absorption of the grout. I was very pleased with the results of all of my sample pieces. I did find that I needed to use multiple, thin coats, about 2-3 coats, for the best results, but the can of coating I purchased goes a long way so I have more than enough. The coating peels off really easily and actually reduces the effort to wash the grout haze off the tile, as the haze is on the coating, not the tile. The final back splash grouting is going to take place sometime over the next two weeks, but I am confident I have found a perfect solution to the problem. Great product! Thanks so much.” – Brenda

 

 

“I bought a gal of Marble Shield 4580 last summer. It is working well for the project I am involved with. I need to know a couple of things however.
1) Is it freeze thaw stable?2) What square foot coverage could I expect to get out of a gal. if I roll it on. Thank You.” -Joe

Our Recommendations: Joe, Marbleshield 4580 is water based peelable coating with Zero VOC, therefore, it is prone to freeze and it is not freeze thaw stable. This product, when cured, is water resistant and is washable. The product does absorb water on prolong exposures and can turn slightly milky. This product is completely clear in the absence of water.

 

 

“We would like some information, and samples, of this material. We are a construction company building high-end custom homes and we need to find some kind of material to protect the wood and stone/tile flooring while construction is still in progress.

1. Does this material work for this installation especially over very expensive material?
2. I see many types of material available on your website and would like to know which material is the best for this application.
3. How much square footage does a gallon cover?
4. We are located in San Diego, what is the shipping time to receive your material?”

Our Recommendation: Marbleshield 4580 is a water based peelable coating which cures upon water evaporation to a clear water resistant hard film. The cured films can be applied to concrete, marble, sealed wood and most other surfaces that are non porous. The viscosity of this material is high and that helps the film to bridge over minute cracks. The coating can be peeled by prying a corner and lifting the paint off. A gallon of Marbleshield will cover 160 to 190 square feet. Application by airless spray is best but it can also be applied with paint rollers.

Application

Marbleshield 4580 is normally used as received. It can be applied by spray, roll or brush . Marbleshield 4580 may also be diluted at the rate of one to four ounces of water per gallon or as needed for proper application. The sprayed coating dries, depending on the film thickness, in 30 minutes to 4 hours. Marbleshield 4580 should be applied to yield a dry film from one to ten mils (.001″ to .010″) thick. The coating, when totally dry, is resistant to water and some solvents used in paint. Application temperatures range from 120º F. for fast force cure to no lower than 45º F. Marbleshield 4580 cures upon water evaporation. Faster cure can be realized by placement of air fans to remove the water from the coating. The coating when applied is milky but when cured is totally transparent. The milky appearance is indicative of water presence in the coating. Brushes, rollers and spray equipment can be cleaned with water immediately after coating application. The coating becomes water resistant when clear.

MARBLESHIELD has good adhesion to the substrate and it can be washed. This product can be peeled only if the paint is pried and then slowly lifted.

Removal: Marbleshield 4580 is removed by peeling. Simply, pry a piece of coating in one corner and lift.

Flammability: Water Resistant Marbleshield 4580 presents no fire hazard as received, during, or after application.

Disposal: Marbleshield 4580 is formulated to exclude ingredients that are deleterious to the painting process, such as silicones, or to the water wash system, such as foam generating or foam stabilizing ingredients.

Operating Guidelines:
When applying, use the same protection as used while applying paint. The ventilation stem should be operating while the material is being sprayed.

 

 

First Time Application

I. Cleaning of Equipment:
To clean pressure pot, airless equipment, spray guns, spray lines:

  • Flush equipment and lines with the current paint thinner (toluene, xylene, or mek)
  • Follow with a water reducible solvent, such as butyl cellosolve. This will help to remove any solvent residue.
  • Thoroughly rinse with water. Making sure that all solvent and paint residues are removed.

II. Cleaning
To clean all surfaces where Marbleshield 4580 is to be applied:

  • Clean surface with butyl-cellosolve type cleaner.
  • Remove all previous peelable coatings, oils, dirt, and solvent residue from the surface.
  • NOTE: You do not have to do this cleaning step to have Marbleshield 4580 peel or rinse off the surfaces. This procedure can be eliminated after the second and all subsequent applications.
  • Marbleshield 4580 can now be applied.

Some Equipment Notes:
Air assisted spray equipment is recommended for proper film uniformity.
