FAQ – Frequently Asked Questions

What materials can the product be applied to (wood, plastic, glass, metal, etc.)?

Pretain’s CleanCoat™ can be applied on any surface, although spraying it on a plastered wall makes no sense due to the high openness of the plaster. So surfaces like glass stainless steel, wood, ceramics, any surface with a smooth surface will work as the coating becomes an integral part of the surface.

What is the minimum order quantity?

To start, our product is only available business to business (B2B).

Businesses can ask for a quotation, regarding our minimum order quantities and prices.

In a school setting or child friendly environment, if the product is licked or consumed, what are the safety ratings/hazards? Are their poison control protocols?

Our coating component is also known as E171 in the food sector and used as an additive as such. Furthermore there is no migration ( tested ) and the hardness is H8/H9 and integrates with the surface and places a very thin layer 1MU on the surface. So our coating is completely safe to interact with (on any way) after its application. There is no need for any poison control or whatsoever.

How does one test the product to know that it is actually still working after application? Does it become less effective over a period of time?

Any coating is always subject to abrasion. Because it is an nano-coating with a very high hardness we give at least a guarantee of 1 year. The best way to check if the operation of the coating is still functional is to use an ATP system to swab test the treated surface. Or with our new test where a substance will discolour. Basically when there is no abrasion the operation will stay functional for many years, like a wall or ceiling.

For the initial and/or subsequent applications, does the product need to be applied by a professional? Are there certifications needed for the applications?

We advise that our coating is applied by a professional, to maintain the quality levels.

Does the naked eye see the product was applied? Examples would be shininess, glare, discoloration, etc.?

If applied according to our standards there will be no visibility of the coating, even on glass or mirrors.

After application, what is the time that it takes to kill the bacteria/virus?

After application the coating will start operating immediately. The functionality of a coating is been measured by LOG (logarithmic phase) that is that the growth of a bacteria is been set off against the dying bacteria, so when the number if dying bacteria is higher that the growth this is calculated in log, log 3 (means 1000 colony forming units CFU 1 cfu remains).
