Lead Paint Encapsulation

One-Coat Paint System Encapsulates Lead-Based Paint and Eliminates Sandblasting

This specification covers preparation of surfaces and the performance and completion of coating of surfaces to safely abate asbestos and lead base paint.

Why is lead dangerous?

Lead is a naturally-occurring heavy metal. Up until the 1970s, it was used to build pipes, as an additive in paint, and in many other manufacturing and construction scenarios. Lead is dangerous because, in short, it’s toxic to human systems. There’s no way to extract lead from the bloodstream once it enters it, and lead levels can build up over time and cause sickness. The EPA cites children and pregnant women as particularly at risk to lead exposure and health defects, but anyone can suffer from lead poisoning (Source).

Lead based paint

Rust Grip® saturates deep into the pores of the substrate. Rust Grip® is made with low molecular weight solvents that act to provide wetting so that deep penetration can occur. After it penetrates, Rust Grip® draws moisture from the atmosphere which reacts with the active ingredients of the base component and results in a gassing effect of the molecules. Molecules expand and swell into all the pores to block out air, gasses, and moisture and to encapsulate the surface.

Rust Grip®
The Ultimate for Encapsulation

Rust Grip^® Is a one-part polyurethane coating that combines with atmospheric moisture to cure. Upon curing, Rust Grip^® provides a protective coating of superior adhesion, flexibility and abrasion/impact-resistance. It is resistant to chemical solvents and acid splash. Originally designed for metal surfaces, Rust Grip^® demonstrates excellent adhesion to wood, concrete, fiberglass and many other substrates. Rust Grip^® is designed for the encapsulation of and adherence to tightly-bonded surfaces of lead-based and other toxic paints as well as rusted surfaces and asbestos.

Surface Preparation

SSPC-SP1, SSPC-SP2, SSPC-SP3, SSPC-SP6 and SSPC-SP12/WJ-3 orSSPC-SP12/WJ-4 Surface Preparation (using low pressure less than 3,500psi/25MPa) depending upon the condition of the surface.

Surface shall be free of all existing mill scale, pack rust, dirt, contaminants, embedded oils, and foreign matter and shall have all loose rust and loose coatings uniformly removed. Surface of any firmly bonded coating shall be sanded and roughed to remove gloss or shiny finish and to improve the surface profile.

Surface shall be cleaned using TSP (tri-sodium-phosphate) or a citrus cleaner to release dirt and degreaser residue.

cleaner to release dirt and degreaser residue. Surface must be completely dry and clean. If surface moisture exists, wipe down with Acetone before application. SURFACE MUST BECOMPLETELY DRY. Use Chlor*Rid, or equivalent to decontaminate surface if salts are present. Acceptable levels: Nitrates: 5-10 mcg/cm2, Sulfates: 5-10mcg/cm2, Chlorides: 3-5 mcg/cm2.

Note/s:

In areas where the loose flakes can be removed, use netting tocatch the flakes when power washed.
In areas where no removal is allowed, RUST GRIP can encapsulate all loose material if rolled or brushed to force the RUST GRIP deep into the surface in order to bridge the flakes with the bonded surface. This may require double the quantity calculated for the job.

Surface must be completely dry before applying.

RUST GRIP® must be applied during proper temperatures (40°F-100°F) and the prescribed overcoat window of the coating over which it will be applied.
If applied over an existing coating having a glossed or shiny finish, it must be sanded and roughed to remove gloss before application, toimprove the profile.

Note/s: Never use a needle gun. This compacts rust into the pores andblocks RUST GRIP from anchoring.

Lead Based Paint Abatement and

Rust Grip & Enamo Grip

No Sandblasting Required or Lead Dust Containment issues

The United States Army Construction and Engineering Research Laboratory (CERL) contracted with Manta Industrial, Hammond, IN to conduct field demonstration and implementation of a cost-effective lead-base paint encapsulation procedure for the protection of steel structures, such as hangars, tanks, and bridges that contain lead-base paint using Rust Grip®. The maintenance and lead base paint encapsulation procedures include surface preparation, environmental protection requirements and paint application. Rust Grip® is patented (Patent #5,695,812) as an effective abatement method of bio-hazardous material including lead-based paints, asbestos and rust.

Rust Grip® is a moisture-cure urethane coating with special additives and resins. It is these additives and resins that separate Rust Grip® from the other moisture-cure urethanes and allows it to be applied directly over existing, firmly bonded paint or rust without any loss of performance. Since the greatest expense in the coating of lead-base painted steel structures comes from the surface prep (abrasive blasting, etc.) and the containment of that residue, Rust Grip® will greatly reduce the overall costs of the project. Rust Grip® was developed to withstand the harshest environments and has a history of excellent performance.

The Problem

Lead-based paints (LBP) and primers have been used in the past by the Department of Defense (DoD) to protect steel structures from corrosion. LBP abatement and disposal is problematic because the removal of this paint creates hazardous dust and waste.

The DoD owns about 2 billion sq ft of buildings coated with some lead-based paint and about 200 million sq ft of steel structures coated with lead-based paint, such as aircraft hangars, tanks, and bridges. The Army owns 95,400 target facilities in the United States and 26,200 in foreign countries. The average age of these structures is 36 years; 90,000 were built before 1978 and probably contain lead-based paint. Furthermore, about 2600 of these facilities are on or eligible for the National Register of Historic Places, and require special procedures for preservation.

The removal of LBP is generally performed by abrasive blasting and abrasive blasting creates its own environmental hazard. Containment and disposal of surface preparation debris, worker protection, and other regulatory compliance costs combine to make removal of LBP very expensive. The residual waste from LBP removal often contains enough lead to be considered a hazardous waste, thereby requiring special handling and disposal.

The Simmons Army Airfield at Fort Bragg contained numerous steel structures such as water tanks, bridges, aircraft hangars, antennas, ladders, poles, railings, catwalks, fire hydrants, fuel storage tanks, and metal buildings were constructed or installed with lead-based coatings. The removal of lead-based paint from steel structures is currently accomplished through a variety of methods, the most common being abrasive blasting which brings many issues such as containment and public safety along with noise and additional cost.

Prior to recoating steel structures, abrasive blasting is required in order to remove the old lead-based paint and to provide adequate surface profile for bonding the new paint to the substrate. During abrasive blasting, a tight containment structure is required to prevent lead dust from contaminating air, soil or water. Inside such containment structures, increased worker protection is required due to high lead dust concentrations. The large, concentrated volume of waste generated by abrasive blasting is hazardous and requires additional stabilization treatment prior to disposal.

Rust Grip® was introduced as a vital strategy to eliminates sandblasting and safely container the lead paint along with the dramatic reduction in cost for the projects on the site. See the full Department of Defence Report.
