Product Description

Zinsser Perma-White Interior paint will bond to existing paints, either solvent-based or glossy paints. It will even bond to ceramic tiling and Formica® without sanding. The paint contains a biocide that serveas a protective shield against fungal degradation. Due to these protective properties against mould and mildew and as a moisture resistant paint, Zinsser Perma-White paint is ideally suited for areas with persistent humidity and poor air circulation, such as bathrooms, basements or laundry rooms. Zinsser guarantees protection against fungal degradation for 5 years.

Their Perma-White Interior Paint comes in two different finishes, matt or satin; both finishes are available here at Rawlins Paints in 1l, 2.5l, 5l or 10l tins. We also stock Zinsser Perma-White Semi-Gloss paint, suitable for both internal and external usage.

Zinsser Perma-White Interior Matt Paint – is ideal for areas where a low sheen finish is desired. As a durable paint with a long lasting protection against mildew and mould, this matt finish will be ideal for basements and kitchens.

Zinsser Perma-White Interior Satin Paint – if you are after a glossier finish rather than a dull sheen, Perma-White Satin Interior Paint will be the best choice. We recommend using this particular finish for areas that are subject to wear and tear. Due to its moisture resistant properties, Perma-White Satin Paint will be ideal for bathrooms and laundry rooms.

Zinsser Perma-White Semi-Gloss Paint – The Zinsser Perma White Semi-Gloss paint is only available in Perma-White Exterior.

questions Jenny on 13/09/2017
Question: Hi, I want to paint over varnished wooden shelves and pre-painted wooden skirting boards in the bathroom - would the Interior White be suitable for this?

Zinsser Perma-White Interior would be a good product for this environment. We would recommend Zinsser B-I-N to prime the varnish first though, followed by 2 coats of the Perma-White. 

questions Doug on 24/05/2017
Question: Hi,
we would like to know if your perma white paint would be suitable for swimming pool ceiling
we are taping and jointing so would be applied to a gtec moisture resistant plasterboard would we need to wash coat or seal prior to the application of the perma white

Thanks Doug

The specification for swimming pool walls and ceilings Zinsser recommend is to prime first with Zinsser AllCoat (Solvent-Based), followed by 2 coats of Zinsser Perma-White Interior. No other sealers required, do not thin either product.

Question: ZN7070001D1
Zinsser Perma-white Interior paint

Am I correct in assuming from your website that despite the name the Zinsser Perma-white Interior paint comes in a range of colours? Are you able to supply a paint swatch book of the colours? Can you also order paint sample pots? Also can you paint on top of this product with a regular paint and still retain the anti-mould properties?

Yes Zinsser Perma-White Interior is available in the range of colours shown on the product page. However we do not offer colour cards or samples due to the colours on offer being industry standard RAL and BS colours (which means they are not unique to the Zinsser Perma-White product). Finally Zinsser Perma-White Interior must be the final finish and cannot be painted over if you wish to maintain its performance properties.

questions Simon on 30/11/2016
Question: I need to paint a newly plastered bathroom ceiling. I'm unsure if l should do a couple of miscoats with this product or if a standard Matt emulsion would be suitable.
May l ask your thoughts?
Thank you.

Prime the bare plaster with Zinsser Gardz and finish with 2 coats of Zinsser Perma-White Interior.

questions Carole on 17/09/2016
Question: Do you have samples for this paint?

I'm afraid samples aren't available for this product.

questions Joe on 31/08/2016
Question: i have issues with mould on ceilings in two bedrooms and bathroom. How do I prep the ceilings before using this paint please?

Surface Preparation
All surfaces must be clean, dry and free from anything that will interfere with the adhesion of the materials to be applied. Remove loose and failing material by scraping or brushing with a stiff bristle brush to a sound edge. Feather sound edges with a fine grade abrasive paper. Remove all visible signs of organic growth and treat the areas with Zinsser Mould Killer & Remover in accordance with the manufacturer’s instructions. Allow to dry.

In areas with remaining sound paint wash with hot water and liquid detergent solution to remove any contaminants, frequently changing the water. Rinse thoroughly with clean water to remove all residues. Allow to dry.

Patch Priming
Patch prime all stained, bare and filled areas with one coat of Zinsser B-I-N Primer Sealer in accordance with the manufacturer’s instructions. Allow a minimum drying time of 45 minutes in normal drying conditions.

Decorate with two full coats of Zinsser Perma-White Interior Matt, Satin or Semi-Gloss in accordance with the manufacturer’s instructions. Allow a minimum drying time of two hours between coats.

Zinsser Perma-White is a durable, water-based, very low odour finish containing a biocode that protects the dried coating against mould and mildew and is guaranteed for 5 years. It is ideally suited for any area of persistent high humidity, frequent temperature changes and poor air circulation.

questions Dave on 01/03/2016

Would this be suitable at protecting wooden structures from mould and fungus in a cellar where we have previously had damp issues?


Yes, Zinsser Perma-White Interior would protect wood from mould and fungus.

If the timber is structural then it should be replaced if there is fungus growing, if it is just shelving or other then proceed as follows to give a good level of protection.

If you are replacing any timber with new then treating first with Blackfriar Exterior Wood Preservative Gold Star Clear would be recommended. You can then prime with Zinsser Cover Stain followed by 2 coats of Zinsser Perma-White Interior.

If the timber is not to be replaced with new and assuming there is no paint on already, scrape to remove the mould and fungus, treat with Blackfriar Anti-Mould Solution and leave overnight. Scrub with hot soapy water then apply a further treatment of the Blackfriar Anti-Mould Solution. Don’t wash this second treatment off, apply Blackfriar Exterior Wood Preservative Gold Star Clear liberally to the dry bare timber, 3 coats wet on wet ideally, leave 3-4 days to dry then apply Zinsser Cover Stain and Zinsser Perma-White Interior as above.

questions Gary Horton on 14/01/2016

We are looking to use the Zinsser Perma-White Interior for our indoor swimming pool hall - could you let me know (i) that it would be suitable; and (ii) how soon can it be painted onto fresh skimmed plaster?


Zinsser Perma-White Interior is definitely a suitable product for this application and what we would usually specify for these instances. The plaster will need to be primed with Zinsser AllCoat (Solvent-Based) before applying Zinsser Perma-White Interior but you must ensure the plaster is sufficiently dry before doing so. Substrates to be coated with this system should have a maximum moisture content of 12%.

questions Bruce Ross on 31/07/2015

I am painting over existing (new) white emulsion in an outdoor "garden room". How many coats of Zinsser Perma-White Interior do I need?


2 coats @ 10m² per litre/per coat are required for proper performance and mould and mildew-resistance.
