FAQ


The highest costs in time and money for any repair/maintenance schedule can usually be found in prep, equipment and labor. The single most obvious advantage for CORRIZON is requiring less costs in each of the above resources. Depending on a contractor’s region, sand blasting, hand tooling/grinding costs that meet or exceed standard preparation requirements (SSPC, ASTM, etc.), will far exceed the price of a CORRIZON treatment and related installation protocol.

Typically, pressure wash to degrease and pressure wash again. As long as there is no loose debris, CORRIZON will encapsulate and penetrate tightly adhered rust and through to the substrate. Apply “Corrizon Base” in thin layer up to 50 microns wet, without over lapping! After drying 15-120 min. depends on conditions apply second layer to the none coated areas. Where needed use paint brush to get to difficult to reach areas, be careful not to over coat.

CORRIZON encapsulates tightly adhered rust to make it into a tough, corrosive-resistant barrier from the environment. CORRIZON then continues to ionically bond to the metal below to create a corrosive resistant barrier to the base metal.

Because CORRIZON is waterborne, there is a carrier included within the product so that when water or moisture comes in contact with CORRIZON it may turn brown or white. This does not affect the performance of CORRIZON. CORRIZON is not necessarily a finish coat.

CORRIZON can be applied as a two-coat system depending on the substrate. If the metal and rust is flat and relatively smooth a one-coat system could be sufficient. However, if there is a wide range of pit ridges on tightly adhered rust, then a second coat may be required. The best application method is cross hatching or north-south, east-west. The second coat should be applied when first coat is tacking or near dry. In full sun and wind this could be as quickly as 10-15 minutes, or up to an hour in darkness or humidity.

Yes, if the damp surface implies a non-pooling substrate. If there is pooling, waste will occur because it will dilute the waterborne CORRIZON and will adversely affect its anti-corrosion properties.

Not at all. This is part of our advantage. For example, if coating the chassis of a car, CORRIZON will not harm the rubber or the isolation of any electric wiring.

Both! Standard CORRIZON is conductive. Just coat and weld joints afterwards. However, if you need your surface to be non-conductive, CORRIZON can also be formulated to inhibit conductivity to provide insulating properties as well.

One of the best characteristics of CORRIZON is that it will not allow corrosion transmission beyond the damaged area. Only the exposed/damaged metal will be affected by the environment and can be repaired with CORRIZON as needed. CORRIZON is a fairly durable coating and should withstand normal abrasions.

Tacky to dry is the key state to look for when waiting to topcoat. CORRIZON operates under two conditions: 1) because CORRIZON is waterborne, the first state is “water release” which takes some time, and 2) its second state is a chemical cure period which encompasses corrosion and binds ionically to the metal substrate. The chemical cure may occur during or after a topcoat is applied (48 hours) but it is imperative that CORRIZON is dry to the touch before any topcoat is applied.

Always stripe any edge either with a spray brush or roller because CORRIZON is waterborne there will be shrinkage as it cures. We recommend a 25% over-spray with airless or conventional spray equipment. A 519 tip or larger orifice is preferred due to the viscosity of CORRIZON. Spraying too thick of a first coat will delay cure time and decrease the bonding between second coat, paint and/or epoxy topcoat. If rolled or brushed short nap rollers are preferred in a light touch over the substrate or completely covering it with CORRIZON. Well joints and pitted areas should be brushed to insure complete coverage and penetration. Any corroded areas with extensive pitting, jagged edges or uneven substrate should be double coated (two coats via north-south and east-west pattern).

Yes. We have extensive test results from Cal Poly San Luis Obispo that confirm (through SEM Testing) interaction between CORRIZON and existing paint and metal substrate, penetration not only occurs but, in some tests, CORRIZON manages to permeate the full thickness of the metal test sheet.
