Of all the different ways to deal with rust, this really leads the pack!
I first saw the use of rust converter some years ago in a metalworks industry
estate in the western part of the island. My response at that moment was : "Geez, why are you applying milk onto the air-con ducting?’ Good thing those words were uttered only mentally, not verbally. That was my first encounter with this amazing product - the Rust Converter.
The milk-like substance, upon contact with rust, first turns the rusted surface blue in colour.
After about 15 - 30 mins, the rust is converted into a black-coloured protective coating that is inert to further oxidation.
Red lead or red oxide primer act differently by covering the rust with a coat of oxidised paint while rust converter actively reacts with the rust. Once the inert black coating is formed, rust is arrested. The metal can either be left as it is, or top-coated with a alkyd, epoxy or polyurethane paint.
The advantages of the Boatman Rust Converter are:
- it can be applied directly onto rust with minimal preparation
- it’s non-hazardous, non-toxic, not flammable
- it’s water-based and easy cleanup (environmentally friendly)
- it’s extremely easy to apply, with brush or roller, or even dipped
While the practical coverage depends greatly on the extent of rust, 1 litre of the rust converter can cover approximately 10 sq m. It dries in 15 - 30 mins but should be top-coated only after 4 hours.

ICI Dulux Pentalite Mouldgard - A933-25664
ICI has come up with a product that solves a particular persistent problem faced by homeowners - mould growth. Mould can appear in many places, but particularly in areas where you don’t want them. Seriously, would you rather have mould present in your storeroom or in your bedroom. I haven’t heard of complaints of mouldy storeroom (yet?) but there seems to be a disproportionate occurrence in bedrooms. Bathrooms and kitchens are also favorite haunts. What they do is create an eyesore on the surface of the paint while slowly digesting the paintwork. With food and moisture, it spreads wider and wider. Before long, the entire wall or ceiling becomes a community of many different types of moulds, giving the wall an unintended spectrum of colours.
Often overlooked also is that moulds are detrimental to health. In a different period in my life, the study of mould spores in the air was, at that time, my only pre-occupation. In infested areas, spore counts can go up to a level that requires quarantine. People have known to fall sick just from exposure. No wonder those TV makeover nannies are usually masked up while cleaning in mould-infested homes.
ICI Dulux Pentalite Mouldgard is designed to prevent moulds from growing on its surface. Like I mentioned, Mouldgard is ideal for bedrooms, bathrooms and kitchens where mould growth is likely. Some characteristics of the paint :
- White in colour
- Smooth, matt finish
- water-based, water clean-up
- dries in 1 - 2 hours, depending
- no lead content
- interior applications only
- coverage of about 10 sq m per litre
- 5-litre pack size
It is good to first prepare the surface by applying Dulux Fungicidal Wash prior to painting. This will kill off existing moulds and spores.
The recommended recoat time is 1 - 2 hours, but in my own use, the drying time can be as fast as under 1 hour if good ventilation exist. I used a commercial grade fan to aid air flow. I always suggest 2 coats to achieve a good finish.
ICI Dulux Pentalite Mouldgard is my recommendation (even if mould growth is only suspected).
I’ve attached the product brochure and the product datasheet for your reference.
