A cost-effective, eco-friendly alternative to traditional rust removal, Interplus 4101 Clean Gel has a thick consistency and sticks to surfaces, making it ideal for cleaning walls and ceilings.

The new Interplus 4100 range provides the perfect solution for surface preparation and the removal of corrosion damage, calcium, salts, humus and magnetite from stainless steel and aluminum structures. The result is a quick, cost-effective and eco-friendly alternative to sandblasting, acid washing or high-pressure water blasting.

Many different environments can create challenging conditions for metal substrates, causing corrosion and a wide range of surface imperfections. These imperfections can be equally challenging to remove, as these substrates are often hard to reach and non-bio-degradable chemicals cannot be used. The Interplus 4100 range has the answer to convenient and cost-effective surface preparation, with the following features and benefits:

• Easy and time-saving application via normal high-pressure pump
• Provides gel and liquid-based solutions suitable for a range of surfaces
• Can be used in offshore environments and drinking water systems
• Suitable for steel, stainless steel, aluminum, plastic and polyester substrates

The full range is compliant with HOCNF (Harmonised Offshore Chemical Notification Format) and contains only ingredients from the PLONOR (Pose Little Or No Risk) list of environmentally safe chemicals. Each product is 100% biodegradable and 100% toxin free, making for a safe and sustainable solution to rust removal and surface preparation.

Surface Preperation

Prior to application of Interplus 4101 Clean Gel, 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 residue, product and rinse water. For further details, contact our technical team on 0113 2455450 (option 2) or send a message to [email protected].

Galvanised surfaces can be affected by Interplus 4101 Clean Gel; these areas should be covered. Use of Interplus 4101 Clean Gel on GRP will cause discoloration of the surface.

Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.

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 12 to 24 hours.

Pure epoxy topcoats can experience white staining when using Interplus 4101 Clean Gel; please test a large enough area before use if this may be an issue.

Application Conditions

Optimal working temperature range is 8 - 37°C (46 - 99°F). Interplus 4101 Clean Gel can be used at temperatures as low as 2°C (36°F) and a maximum of 60°C (140°F), but a lower level of performance should be expected.

For best results, it is advised to suitably cover the application area to reduce the effect of wind, rain and intense sunlight.

Application

Product Characteristics

Maximum film build in one coat is best attained by airless spray. When applying by methods other than airless spray, the required film build is unlikely to be achieved.

Typical working pressures for airless spray application are approximately 105kg/cm² (1500 p.s.i.). This allows both an even atomisation and film formation to be acheived. Excessive pressures should be avoided as this can lead to poor atomisation and film formation thus reducing product efficiency.

The removal rate of rust deposits is dependent upon the thickness and uniformity of Interplus 4101 Clean Gel. Repeat applications may be required for areas where the rust level is high.

Test patching is recommended to determine activation time and removal efficiency prior to full application.

When applying Interplus 4101 Clean Gel in confined spaces ensure adequate ventilation.

Treated areas should be wrapped in polyethylene where high temperature airflow or direct sunlight may cause drying out.

Treated surfaces should be overcoated as quickly as possible to prevent the onset of re-oxidation.

Interplus 4101 Clean Gel must be protected from freezing at all times during storage.

Systems Compatibility

To ensure good overcoating of approved maintenance primers, it is important that the treated surface is free from all residue contamination and a thorough rinsing and wash down has been undertaken.

The surface should be clean and dry prior to overcoating with approved primers.

The following primers are approved for application direct to Interplus 4101 Clean Gel treated surfaces:

• Interplus 356
• Interseal 670HS
• Interzone 954
