Product Description

International Interplus 614 is a single component, water based rust remover gel, which can be described as readily biodegradable as tested by OECD 301B CO2 Evolution test.

Best Uses

Interplus 614 is specifically designed to remove tightly adhering light to medium rust deposits from metallic substrates prior to repainting with approved maintenance coatings. Suitable as an alternative surface preparation technique where abrasive blasting, ultra high pressure hydoblasting or power tool methods have been ruled out for operational, health & safety or environmental reasons.

Interplus 614 is to be used in conjunction with maintenance products requiring a substrate preparation similar to ISO 8501-1 St2. Can be used to remove ferrous corrosion staining from stainless steel structures and zinc corrosion products from aged epoxy zinc primed surfaces.


Prior to application of Interplus 614, any loose rust deposits should be removed to aid penetration of the product. Surfaces not to be treated should be masked and protected with polyethylene. A strong ground sheet should be used to contain coating residue, product and rinse water. Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning using Interplus degreaser.

Test Patch
It is strongly recommended that a small test patch should always be carried out on a representative area in order to ascertain the optimum application thickness and activation time required to successfully remove the rust deposits. Activation times are very much dependent upon the in situ rust level and condition, however, a typical working time is within 6 to 16 hours. The resultant rinse washings collected during removal should be analysed by an independent laboratory to ensure disposal in accordance with local environmental legislation.

Application Conditions
Optimal working temperature range is 5 - 35°C (41 - 95°F), however, it can be used at temperatures as low as 0°C (32°F) and a maximum of 60°C (140°F). For best results, it is advised to suitably cover the application area to reduce the effect of wind, rain and intense sunlight.
