Paint blistering over Turbo Builder’s Bog?

Subject: Contact form submission: Ray
Message : Hi
Have used builders bog on a renovation in gym pie Queensland Aus. After filling with the product on the exterior damaged areas of hardwood clapboard, ie joints nail heads etcetc,
The  exterior was given 3 coats of water based self priming exterior grade paint, pascal sunscreen. The exterior came up well I was happy with the result.
Over the past few weeks the area has had some significant rainfall. The areas of the house that are most exposed to the weather have started to have the paint bubble. With moisture appearing between the paint membrane and the filler. The problem is confined to where the filler has been used nowhere else. The pascal paint techs think it may be a reaction of the filler to the paint as exterior moisture increases at exposed areas during a rain event. It is my understanding that the filler which was purchased from Bunnings can be primed with either water or oil based paints.
I would appreciate your techs looking into find a possible solution


Hello Ray,


Firstly may I say I am sorry to hear of your problem.
Builder’s Bog, once cured with the correct amount of hardener, is very inert. Nothing dissolves it and there are no active substances within it that can react with paint.
It will absorb and desorb moisture like timber, but the moisture has no effect on it. As a result, if the timber itself has access to ambient humidity it will expand and contract, and the inert Builders Bog will not move as much. So a nail head fill may seem to contract when in fact the timber has expanded around it, especially if pilot holes were not drilled for screws and the screw head is just crushed into the timber fibres to countersink it before filling.
None of this seems to relate to your problem though.
I have exterior handrails¬† on my¬† 100 year-old house, painted with a very dark green Dulux water-based paint and it has repeatedly blistered in various places. Some¬† blisters are between the Dulux water-based primer and the top coat, some between the primer and the filler, some between the primer and older oil-based paint and some between the timber and the primer. The problem was that this dark green should have¬† been factory-made from a prime grind of pigment powders¬† and resins. But the shop actually tinted it in-store, and this introduced too much of the colour paste, which contains glycols, which spoilt the paint! Being a very dark colour it got very hot on handrails too, which caused the blistering. The glycols etc are in the “universal tinters” to convert the colour powders to a paste for blending in-store.
Can I ask what colour your Pascal paint is, and was it a shop tint?
The only other possibilities, and I am not suggesting they apply in your case, are under-cure due to too little hardener, or too much hardener leaving excess very reactive peroxide behind in the fill. Both will upset the paint, but the permissible range, as in the directions, is very large.

Stuart Jordan
Managing Director




Hi Stuart,


Thanks for responding. The paint color is a light color from a white base “Strauss White”, shop tinted specifically at a masters hardware store. The color was chosen as experience has shown a light color has less heat stress etc etc. The blistering occurs mainly on the south side of the house which is exposed to the predominate weather which usually comes from the southeast. The boards trim on this side get wet up to close to the eave overhang the rain hits these areas and it gets quite a soaking under certain conditions. The southern side of the house was the last to be patched sanded and painted. To this stage I had used 2 tins of builders bog and was comfortable working with the product I have also had plenty of experience dealing with similar products. I am sure that it was mixed and applied as per directions. Could an application of an oil based or acrylic primer (after sanding repatching etc) applied to the filler and then 2x coats of pascal acrylic stop recurrence. Which product would be best an acrylic or oil based primer. Is there any other solution?
Kind Regards


Hi Ray,


Thanks for the reply. An oil-based primer would be safer, because some of the acrylic based primers are very thixotropic and can flash-dry in hot weather before penetrating the surface of the filler or, in fact,  penetrating smooth timbers too.  This just gives a top skin with no real grip on the substrate. Oil based paints are inherently more penetrating.
I never solved my dark green handrail blisters. None have popped in the last (third) rectification run, and Dulux walked away from it, leaving me with a 20 litre pail full of the same paint!
I got too busy to chase it.
No help to you, I know, but you have my sympathy. I spent a long time investigating this close-at-hand failure of paint over our product and¬† over other paints and timber. I am an Industrial Chemist and we have a full laboratory at my company. I formulated Builder’s Bog many years ago. We are also polyester resin experts and supply thousands of tons per month to the fibreglass industry in NZ and the Islands, so we cannot afford to take failures lightly.
he cured surface of Builders bog is different from timbers (which all differ greatly too from one another). If you look under the microscope you will see millions of tiny craters in our filler, put there to allow the paint to get a  good grip on the surface. The inside of these craters is borosilicate glass, believe it or not, from the half-sanded hollow bubbles we use in the filler. These glass hemispheres are both hydrophilic and oleophilic, so they are wetted by both types of paint. But water-based paints need a chance to penetrate and stick before flash-drying, so this could be the problem.
Contamination with oils, silicones, dust are other causes, of course. A wipe over with solvent is a good way to be sure you are free of these. Turps will not affect the timber or Builder’s Bog, but will remove any contaminants and dust.
Stuart Jordan
Managing Director


Hi Stuart,
I will give the oil based primer a shot. I’m fairly confident it shall stop recurrence. The first thing I did when I saw the problem was check some online forums re painting timber exteriors in Queensland most recommended using a undercoat sealer primer on all patching with two coats of finish coat over, I shall let you know how it goes. I’m painted out at the moment so may not get to it for a week or so.
Many thanks for your prompt response and potential solutions
Kind Regards

Customer Testimonial

Subject: Contact form submission: Alan McLean
Message : Hi Chem. Specialties.


I have a problem with rotting corners on my fascia boards. Having scraped out all the rotting wood I have been advised to then treat with an anti fungal solution. Is this necessary when using your Builders Bog ?
Would appreciate your reply


Many thanks,







Hello Alan,
Any active spores in wood surrounding the repair will continue to rot the surrounding material if you do not kill them. Since some antifungals will interfere with the Builder’s Bog curing chemical reaction and the bond to the timber, I advise you to scrape, chilsel, or cut out all softened wood back to sound timber, then perform the fill with Builder’s Bog. Then drill some holes above (if a vertical surface) or around the repair, inject (squeeze bottle with spout etc) a water- or glycol-based antifungal solution that will soak into the surrounding timber. Then plug the holes with dowels and smooth over and paint.
This is the only way to be sure you have inactivated further rotting from fungal spore left behind.
I cannot tell you what brands to use since this depends on what your local stores stock, but anything mentioning ethylene glycol and/or boron or borax or boracic acid will work well. Things like Metalex, naphthenates and “wood hardeners” are surface coaters and will not penetrate enough to reach surrounding spores. Plus they cannot be applied before the fill because they will spoil the bond to the timber
I hope this helps.




Stuart Jordan
Managing Director




Hello Stuart,
Many thanks for your reply to my e-mail and on the same day. This was excellent service especially the detailed description on how to repair my problem.
I have always used your product as it is the best on the market.


Once again many thanks,


Alan McLean.

Builder’s Bog

Is it not great to have the manufacturer ‚Äúon site‚ÄĚ with you?¬† Realising DIY ‚Äúfirst time users‚ÄĚ of our products may feel unfamiliar with our products, our technical information is available at your fingertips by going to the mobile version of our website on your phone or send us an email.

From time to time I get emails from people who want to know more about our products, product uses, mixing tips and if that is the case, what are the guidelines. I figured that it would be easier to write the guidelines in a post and just refer every one here.

So the answer to the first question is: Yes, I do accept all questions here and I do answer all of them. Currently I received question from our customer who is about to use Builders Bog on the beams in her ceiling.


Here is the question:



I am about to use Builders Bog on the beams in my ceiling.¬† The nail holes are worn, and the roof is coming loose!¬† I will “bog up” the beams, then replace the roofing screws.

My question is:  How long is the bog workable.  That is, will it harden to a point that it will be too hard to drill and, therefore, replace all the required screws. There are a lot to do, and while I can probably apply the bog fairly quickly, it is going to take some time to get to all the screws that need attention!

My second question is:  Should I wait until the bog is hard before replacing the screws?

Never done this before!  : -)

Thanks, Elizabeth


Every question is important to me. So I replied to Elizabeth the following day to help her to understand our product and use Builder’s Bog to achieve her objective. Here is my answer:


Hello Elizabeth.
An excellent question. When fully cured, Builders Bog sets about as hard as timber and can be nailed , drilled and screwed.  So I would fill all the nail holes, let everything cure for as long as you wish, then drill pilot holes for the roofing screws and drive the screws in.
I am not absolutely sure what you are about to do.¬† You say the nail holes for the “roof” have come loose, but mention the “ceiling” beams. Presumably the roof is iron and you will remove the sheets to access the nail holes and fill them.¬† This is not easy and it is also very difficult to get any type of putty consistency down into a nail hole.
Since roofing screws are thicker than lead head or other roofing nails , normally a screw will drive perfectly well into an old nail hole in which a nail has come loose, without any filling being necessary.
Have I got this wrong? “Ceiling beams” and “roof nails” confuses me a bit.¬† There should not be any
roof nails in the ceiling beams. Is it the inside ceiling that has come loose?¬† The same answer applies – just let all the Builder’s Bog harden and cure before screwing into it.
The roof nails¬† fix into the¬† perlins which run across the rafters. ¬† Ceiling beams or joists tie the walls together and resist the out-thrust of the roof rafters, which are pitched above them to make a loft or roof space. An iron roof is not normally nailed directly into the rafters (“beams”), but to the crosswise perlins which stabilise the rafters and hold them square.
Attached is a drawing to clarify. They call the perlins “roof battens” in this illustration.

Stuart Jordan


I am¬† very pleased to find out¬† Elizabeth’s question¬† was answered to her needs and indeed she was very complimentary about our response.


Dear Stuart,

Thank you so much for your most comprehensive answer, and the wonderful diagram!¬† (I have been telling students all day “It’s all about the jargon, it’s all about speaking the same language.”¬† This is a perfect example!
You have answered my most important question:¬† How much time to I have before the Bog is “too hard” to work.¬† Now I know I have “as long as (I) wish”!)
To use the correct terminology:¬† The roofing screws that hold the tin down are so loose I can jiggle them up and down with my fingers!¬† I can lift whole sheets of tin in some areas!¬† Fortunately, we are extremely well protected from wind;¬† otherwise we would have lost that tin years ago!¬† (I suspect that the constant “up and down” movement of the tin, pulling on the already loose screws, has just stripped the holes of any thread.¬† I have tried replacing the roofing screws with a slightly larger gauge screw … but I cannot go any bigger without starting to use something akin to a bolt!¬† I have even tried longer roofing screws, but I still have a few screws loose upstairs!¬† ; – )¬† )
So it will be very easy for me to lift the tin to apply the bog to the BATTENS.¬† (Trying out my new vocabulary … )
I am handy with a drill, and nimble enough to run around our roof, so the rest will be easy once I have the bog in place. I will give you another big THANK YOU for this diagram.¬† I have a beam that needs replacing, which is either a “collar tie” or “purlin” …and now I will be able to understand what the builder is saying to me when I talk to him!

So thank you again for your support, it is most impressive.  And thank you for a great product.  I am looking forward to playing with it!

Warmest regards, Elizabeth


Although our product is easy to use and with it you can achieve great results, the fundamental chemistry is quite advanced and has been perfected over 25+ years by us. I am very happy to help people to understand our products and how they work, I am happy to answer every single question even if the question may sound very elementary to you. It also help me to realize/find out where and how people use our products, what steps they are taking to use it as well as what tools and material they use.

JEC EUROPE 2013, Paris. 12, 13 and 14 March 2013

Brett Scholes (Sales Engineer ‚Äď Synthepol) and Phil Breytenbach (General Manager) attended this exciting exhibition. As can be expected, space age materials and Airbus 380 related parts dominated. If you could not at least show a picture of an Airbus 380 part on your stand ‚Äď well, then you probably did not deserve to exhibit in Paris!!! In the words of an official at a raw material supplier‚Ķ‚ÄĚnothing revolutionary‚Ķperhaps only evolutionary‚Ķ!‚ÄĚ

Another significant portion of the exhibition was allocated to natural fibres. Various leisure- and automotive industry related mouldings were exhibited ….

‚Ķand then it started to snow and snow and snow‚Ķ‚Ķand then Brett accidentally picked French ‚ÄúAndouillette‚ÄĚ sausage off the menu‚Ķ(pictures are available at a nominal fee‚Ķ..)!

Exciting was the dominating Scott Bader exhibition! Various Scott Bader key staff from the UK, the UAE and elsewhere in the world attended. An intriguing moment was when Phillip Bruce, Group Managing Director, mounted a lovely glossy violin case moulded in Crestapol, a methacrylate-based thermosetting resin ‚Äď ‚Ä¶because ‚Äú‚Ķ how can I represent my company products without knowing how strong they are?….‚ÄĚ Peter Hedley, Latha Ekambaram and Biju Krishnankutty (Scott Bader Dubai) were the perfect hosts and patiently dealt with all our question‚Ķ Thanks Guys!

Puffed up with knowledge on the Scott Bader Crestabond methyl methacrylate structural adhesives, CrysticROOF roof waterproofing system, Crystic Crestomer urethane acrylate structural adhesives and the well known Crystic world leading gelcoats and resins, Brett and Phil left to return to New Zealand…

‚Ķbut not after a ‚Äúquick‚ÄĚ trip on the Shanghai Maglev high speed magnetic levitation train at 301 km/h!!! From a standing start to a complete stop between two stations 30 km apart: 8 minutes!!

Looking forward to seeing the Scott Bader colleagues again, at the New Zealand Composites Conference in August 2013!

Hong Kong International Building and Decoration Materials & Hardware Fair, October 2012

 On Saturday 27 October the South China Morning Post in Hong Kong in a special report, reported;


“Taking part in the trade fair for the first time is Chemical Specialties (booth no 8-J05) from New Zealand, which makes two-pack polyester based putties that are used to repair wood, metal, ceramic, fibreglass and concrete. General Manager Phil Breytenbach says the company is poised for growth after exporting to Australia for many years.



We believe there are no direct comparable products available elsewhere in the world. This is the first time we are exhibiting in Asia. We have chosen the HKTDC Hong Kong International Building and Decoration Materials & Hardware Fair, because of its reputation to bring together world class manufacturers and reliable distributors. {We hope} to secure distributors to retailers in Asia with whom we can develop the market,‚ÄĚ he says.


The company‚Äôs display concentrates on Turbo Builders Bog, a wood repairer, and Newtech Repairer, a strong metallized repairer for mending metal and concrete. The product comes in two parts ‚Äď the putty and a hardener which is mixed with the putty to make it cure. Both can then be shaped, machines, nailed, screwed, sawed and painted ‚Äď similar to the original part which has been repaired in a very economical way‚ÄĚ


‚ÄúSubsequent to the exhibition Chemical Specialties Ltd. has appointed the Hong Kong and China based companies in the ‚ÄúTop Group‚ÄĚ group of companies under the competent leadership of Mr. Wilson Lau as our distributor. A follow up visit to Hong Kong has since taken place with on the spot product training by Mr. Graham Wigg; our Melbourne based International Sales and Marketing Manager, and his wife Christine Wigg. The Chemical Specialties strategy is to always provide excellent backup service to our valued customers when ever and where ever they may need it‚ÄĚ.


Phil Breytenbach
