Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non- specialty grout. It was developed from other types of hydraulic lime in England in the mid 19th century, and usually originates from limestone. Materials that contain appropriate amounts of calcium compounds, silica, alumina and iron oxide are crushed and screened and placed in a rotating cement kiln. Ingredients used in this process are typically materials such as limestone, sandstone, marl, shale, iron, clay, and fly ash.

The effects of PrepEtchTM are created by its two principal components: A blend of organic urea hydrochlorides (salts)and surfactants to arrest Portland cement and convert it to mush. This residue is easily washed and swept away.

It’s recommended that either safety glasses or goggles be worn along with latex gloves as it may cause eye or skin irritation. It is mild, but like all chemicals (paint included), exercising caution is recommended.

The vapors if any emitted from PrepEtchTM are similar to latex paints and are not harmful, but it is always recommended that it be applied only in well ventilated areas.

Good surface preparation will enable the Rust- Rehab to work effectively and leads to a high quality end result. On very large area you can remove most loose and scaling material with a high pressure blast. You will want to remove large rust and scale particles with a stiff bristled brush, hammer or sandpaper. The object of this step is to get any loose or flaking rust off as it does not provide a stable surface. The point is not to remove all the rust (this defeats the purpose of Rust-Rehab) as Rust-Rehab chemically bonds to the rust and seals it in. Rust-Rehab cannot penetrate grease or oil, so clean and degrease the surface first, then let it dry. This step ensures that other surface contaminants will not interfere with the reaction of the Rust-Rehab on the rusted surface.

Good surface preparation will enable the PrepEtchTM to work effectively and leads to a high quality end result. All cementitious surfaces must be free of existing coatings, sealers or curing compounds. Test surface by applying a small amount of PrepEtchTM to the surface. If a light foaming action is present, it is effectively beginning to clean and etch the surface. If no foaming action occurs, remove foreign material by stripping with applicable chemical or mechanical stripping methods.

PrepEtchTM can be applied with a brush, roller, or hand pump sprayer. It can also be sprayed with airless or garden type pump sprayers.

One gallon can cover up to 200 square feet of concrete for an average profile of CSP 2-3 depending on concrete age and design mix.

Most applications require only one coat. Applying a second coat assures uniform coverage and desired profile.

No, all cementitious surfaces must be free of existing coatings, sealers or curing compounds.

PrepEtchTM should not be diluted and should be applied as it comes out of the container.

For best results, applyRust-Rehab with a brush or a roller.Use a brush for smaller applications and a roller for larger surfaces. It can also be sprayed with airless or pump sprayers.

One gallon can cover up to 400 square feet of rusted metal. Porous, textured and irregular surfaces will require a heavier application rate.
