Moist Metal Grip

The ideal protection in harsh, wet environments


Technical Data Sheet (pdf)Application (pdf)Safety Data Sheet (pdf)SPI Coatings


Moist Metal Grip is a two-part (2 component), touch adherent, epoxy coating which produces a hard, yet flexible coating film designed for application on dry, moist, wet or submerged surfaces for protection against corrosion and chemicals. Moist Metal Grip was developed to be applied to metal surfaces that cannot be dry enough to use Rust Grip® or already experiencing moisture or condensation that cannot be stopped and dried.

Moist Metal Grip, the waterproof paint for metal, can be applied to dry or wet metal surfaces to protect against corrosion and chemicals in a two-part waterproof – water repelling epoxy coating. It was designed to be applied to surfaces that are not dry enough for other waterproof paints and coatings.

It can be applied by spray, brush or roller, even while the surface is wet to force the coating into the surface pores, to replace the moisture or water, and to lock down and prevent the combination of moisture and air to allow corrosion to exist or continue. It demonstrates excellent chemical and solvent resistance when utilised in harsh atmospheres, and will also provide outstanding water and humidity resistance.

Moist Metal Grip is ideally suited for surfaces that will be submerged or subjected to constant water pooling or condensation. Moist Metal Grip is ideally suited for metal or steel surfaces that will be underwater or subjected to constant water pooling, condensation,  high humidity, or steam. It can be applied directly over flash or surface rust without loss of adhesion.

This coating will adhere tenaciously to a variety of substrates, such as carbon steel (phosphated or non-phosphated), wood and concrete. These products can be utilised in DTM (direct-to-metal) applications, with excellent success, as they have been fortified with a very efficient, non-toxic, rust inhibitive pigment.

Enamo Grip® can be applied as the top coat to stop condensation and is available in clear, white, and custom colours. It is designed to be applied directly to metal, concrete, masonry, and wood. Moist Metal Grip is a perfect solution for protecting corroded, wet, or condensating cold water pipes. It can also be used to coat re-bars for concrete, buried I-beams, water tanks, cooling towers, submerged structures, car wash equipment, boats, and more.

Moist Metal Grip is resistant to water, solvents and humidity. To apply, remove algae and residues from wet surfaces, then apply Moist Metal Grip directly to the surface, with firm pressure to force the coating into pores. Moist Metal Grip can be applied directly over flash or surface rust without loss of adhesion.

Permanent Antifouling Coating Solution

Moist Metal Grip is the perfect solution to managing antifouling for boat hulls as to slow the growth.

Club Marine describe antifouling as objects left in the water are soon coated by algae (slime) and will eventually be colonised by larger organisms such as barnacles, mussels and seaweeds. This is called biofouling. How quickly and to what extent this happens depends on whether the object is stationary or mobile, as well as the local conditions, which include tidal strength, water temperature, salinity, quality of nutrients and amount of light filtering into the water.

Biofouling on a hull forms a rough surface, which creates drag that slows the boat down, reduces manoeuvrability and impacts fuel efficiency. If the growth infiltrates moving parts and hull openings, these can seize up or block, potentially causing all sorts of trouble.

Antifouling is the ability of specifically designed devices and coatings to remove or prevent biofouling. Antifoul paint is a chemical treatment that’s applied to a hull to make the surface uninhabitable (or at least very undesirable) for aquatic organisms. Antifouling is necessary on boats that are on the water for any length of time, especially if they’re kept there while not in use. By definition, that’s all boats.

Negatives to traditional antifouling paints:

  • Ablative paints erode over time and effect the waters and local marine environment
  • Antifouling paints contain harsh, active chemicals
  • Extra maintenance and time
  • Extra ongoing costs

Benefits for SPI Coatings antifouling paint alternative coatings:

  • Better fuel efficiency
  • Save money
  • Easier maintenance
  • Less slip time
  • Better for the environment
  • Stronger impact resistance
  • 3 times longer resistance to biofouling
  • No more reapplication of paints
  • Superior to current antifouling solutions and processes

Changes to legislation

The boating population is growing worldwide and with it the environmental impacts. The US Environmental Protection Agency wants to limit the paints used on recreational vessels. The State of California already has. Washington State was due to ban copper in bottom paints in 2018. The ban has been delayed, but only because the alternatives were found to be toxic as well. More research is being done on the alternatives but restrictions on copper leach rates are under consideration. European Union authorities are also concerned and Sweden and the Netherlands have partial bans (Source).

Due to Moist Metal Grip‘s tough, no grip exterior it makes cleaning of a boat’s hull simple and no need to reapply any antifouling paints therefore saving you money. To make it even better apply Enamo Grip® over Moist Metal Grip and you’ll create a permanent non-stick barrier to those slow growth biocides.

Moist Metal Grip is EU certified for potable water usage and approved by European standards. Approved for indoor use in water storage tanks (American Water Works Association). It is tested to withstand temperatures up to 176°C (350°F) and for 450 hours of salt spray exposure.

Benefits

  • Fast Acting: Submergible after only 48 hours of cure time; will finish curing while submerged.
  • Durable: Acid and chemical resistant.
  • Versatile: Can be applied to steel, aluminium, wood and concrete.
  • Easy to Apply: Semi-self-leveling formula with a smooth finish that can be tinted to any colour. Can be applied directly to a wet surface using spray, roller or brush.
  • Convenient: Can be applied to moist, wet, or condensating metal surfaces that cannot be dried before applying a corrosion paint or coating.
  • Protective: Prevents corrosion of coated surfaces due to the damaging effects of submersion, constant pooling, or moisture exposure.

  • Very resistant to splashes and spills of acids and solvents.
  • Very resistant to impact.
  • Can withstand subsea pressures for pipelines along the seabed
  • Useful life of 10-20 years in the most aggressive environments.
  • Can be applied over existing PRE coatings that are firmly adhered to the substrate.
  • Withstands temperatures up to 176°C.
  • Withstands traffic, ideal for floor application.
  • Pot life is after the Base and Cure are mixed and you have 4-6 hours (according to ambient heat). If you open a pail and are not using all, then simply reseal the lid with plastic sheet and tape down the lid and seal or put into another can and seal with lid.
  • The BASE will lose some solvents if left open but nothing sets up because no Curing Agent was blended into it. Same goes with Curing Agent. Just get the amount not being used into a can and sealed so that you don’t lose solvents.

Applications

  • As a one-coating system for metal that is moist, in high humidity or submerged surfaces
  • As a one-coating system to encapsulate existing rusted surfaces
  • As a one-coating system to protect metal with condensation issues
  • As a one-coating system to line tanks
  • As the only protective coating against corrosion in buried pipes. As an internal lining for drinking water tanks
  • Very good acid and good alkali resistance
  • As a metal or concrete floor covering
  • As a primer before Enamo Grip is applied

Application

Moist Metal Grip can be applied to metal, as well as concrete or masonry substrates. The coating can be applied by spray, brush or roller. For specific instructions on surface preparation, mixing and application, please refer to the SPI’s application instructions for Moist Metal Grip

Application example

Challenge: Client was hoping to seal the inside of a water feature/pool made of corten steel to stop the fine rust particles (almost like dust) from making the water cloudy/dirty. What product was recommended? Also what types of colour mixes can be added to the Moist Metal Grip and how’s the final texture/appearance it leaves.

Answer: As the corten steel has constant water against it Moist Metal Grip would be the best coating. Do not use Rust Grip underwater. As to UV, all epoxies are subject to chalking or fade with UV. If you are more than 5 feet below the surface, then UV will not reach down far enough to cause a problem. We suggest Enamo Grip on surfaces facing UV to spot rust and it will not fade or chalk. Final texture is smooth.

White Moist Metal Grip can be tinted only slightly. The white pigment overpowers any tint. If you added more than 10% by volume tint, it changes the ratio of the Base-to-Curing Agent and it creates curing out problems. In tinting – do not put water-based tint in a solvent Base and it does not blend. Use water with water and solvent with solvent. Best tinted in the factory.
