How can I get a nice wood-grain finish that stays protected over the years?
Achieving a visible wood grain look with durable UV protection is a challenge for most coating products. As you apply coats of pigmented stain over the years, more pigment is added to the surface of the wood and the more the grain of the wood is hidden. (Paint completely hides and the grain of the wood as it is opaque) Our suggested system is 2 coats of BRODA® PRO-TEK-TOR Premium Natural Oil Wood Finish, (in 000-series or 100-series colours) followed by a clear top coat. Maintenance coats are applied when the surface of the wood loses the sheen that was apparent after the first 3 coats. The recommended maintenance coat is then a coat of BRODA® PRO-TEK-TOR SLT Clear UV Top Coat. This product does not have pigment and thus will not contribute to hiding the grain of the wood over the years as you do maintenance.
Why is surface penetration so important?
Pro-Tek-Tor is a safe penetrating product. As such, the surface of the wood must be clean and the pores of the wood must be open to allow the wood to absorb as much Pro-Tek-Tor as possible. It is also important to kill as much of the mould and mildew that may be present in the wood as possible, to ensure that they do not continue to grow under the Pro-Tek-Tor-coated surface. This will provide the optimal result whether you’re working with exterior finishes, furniture paint, floor stains or our many other products.
Why does Pro-Tek-Tor sometimes have a milky appearance after it has been applied?
This is the result of humidity and temperature. The milky appearance will disappear in a short period of time and has no affect on the performance of the product.
If the sun suddenly comes out on what started as a cool and cloudy day, what should I do?
Mist water to the area where you have used Pro-Tek-Tor natural wood finish, as it must stay hydrated to continue to penetrate the wood. Pro-Tek-Tor needs to penetrate deeply into the structure of the wood for optimal performance. Continue to wet the wood until the temperature cools below 21ºC. The surface of the area where Pro-Tek-Tor was applied should never feel sticky. This is an indication that the natural wood oils do not have enough water to flow into the wood.
Why is wood maintenance so important?
Regular maintenance allows the finish to continue looking good as new. By washing the wood surface, dirt, mold and mildew spores are washed off and do not get a chance to start growing and penetrating into the finish and wood. A certain percentage of the Pro-Tek-Tor is worn away by wind, rain, pollution and sun. With minor regular maintenance, the finish can be easily preserved, avoiding the need for complete restoration at a later date.
Why is it so important to get Pro-Tek-Tor to penetrate?
Allowing Pro-Tek-Tor to penetrate deep into the surface of the wood enables it to fill and bond to the cells of the wood. UV damage is usually only microns deep behind clear or transparent finishes. This damage is what causes surface film finishes to lose their bond to the wood. When Pro-Tek-Tor is able to penetrate beyond this depth, UV damage is greatly reduced.
How does Pro-Tek-Tor allow a transparent or semi-transparent finish to be maintained over time, without making the wood grow darker and darker, as most finishes do?
When the natural oils of Pro-Tek-Tor penetrate the wood, they take the colour pigments with them. Applying the clear topcoat over the initial tinted layers protects the wood's colour and the wood itself. As the clear coat is regularly maintained, the tinted layers are protected from colour fading, tannin stains and water stains. The clear coat has no pigment in it, so the appearance of the wood never grows darker.
Why does the clear top coat have to be applied?
The clear topcoat protects both the surface of the wood and the tinted stain that has penetrated into the surface layers. The topcoat also has special UV inhibitors to stop the pigments in Pro-Tek-Tor from fading. That provides the optimal result whether you’re staining wood or working in another application.
Can Pro-Tek-Tor be applied over other finishes?
No. In order to be effective, Pro-Tek-Tor can only be applied to bare wood. It is very important that Pro-Tek-Tor penetrates into the wood and bonds to the wood itself. Another finish between Pro-Tek-Tor and the wood will prevent this from happening.
Can Pro-Tek-Tor be used indoors?
Yes. Pro-Tek-Tor works very well indoors, and has a very low odour. It is also non-toxic and is non-flammable. Pro-Tek-Tor will not darken over time, leaving the interior bright and natural looking.
Why does Pro-Tek-Tor not have a shiny finish?
Shiny finishes are achieved by applying surface films that stay on top of the wood. When applied correctly, Pro-Tek-Tor will not form a surface film, since it penetrates deep into the wood. A semi-gloss appearance can be achieved by applying enough Pro-Tek-Tor to fill up to the surface of the wood.
How do I fix water stains that occur when Pro-Tek-Tor that hasn't completely dried and is suddenly exposed to the rain?
Apply a mixture of 75% water and 25% clear Pro-Tek-Tor to the stain and rub vigorously with a Teflon scrub pad. Pro-Tek-Tor will reactivate itself and the pigments will begin to move. Continue to scrub until the water stains are gone.
Can Pro-Tek-Tor be applied when it is raining out?
Yes, but Pro-Tek-Tor cannot be applied to wood that is getting wet from direct rain, or wood that has rain running across it. Siding or soffits can often be coated with Pro-Tek-Tor, as long as they are protected from rain by overhangs or tarps.
How long will Pro-Tek-Tor last?
Pro-Tek-Tor will continue to look like new as long as regular maintenance is done on an "as needed" basis. As a premium quality water based wood stain, Pro-Tek-Tor will last as long or longer than any other premium wood product on the market.
WOOD MOULD & FUNGAL STAINING FAQS
How do I clean old wood?
Graying as a result of UV damage, dirt, iron stains and light surface mould and mildew can be removed with ABR X180C. To remove fungal staining (e.g. sap stain), apply a diluted bleach solution and rinse well. Then apply a 9:1 dilution of X180 and rinse well. This will lighten the stains but will not remove them completely.
What is fungal staining?
It is a fungus that generally grows in the sap wood and stains the wood blue or black. The stain is often the full depth of the sap wood.
What does mould and mildew look like on wood?
Generally, it is a black stain on the surface of the wood.
How do I remove motor oil stains from wood?
Oil stains can be removed by applying a coat of ASC All-Surface Cleaner and rinsing off. Then apply a 9:1 dilution of X180C and rinse well.
I am trying to find a safe natural looking clear finish for exterior timbers that will protect them properly over the long run but still maintain a natural look. Will BRODA® keep timbers looking good over their life as long as we regularly re-apply periodically?
We would recommend one of our tinted clears – BRODA® Pro-Tek-Tor SLT Natural Clear or Woodlands Clear.
BRODA® Pro-TekTor has clear, transparent and semi-transparent colours.
UV protection is provided mainly by pigments. UV inhibitors are also added, and mould and fungal protection is provided by fungicides.
The Broda Pro-Tek-Tor products will protect your timbers and keep them looking good for a long period of time if you apply them as recommended.
SAFE SEAL FAQS
I am laying a plywood subfloor over a concrete floor with radiant heat and would like to seal the plywood with Safe Seal. Would you recommend treating one or two sides?
One side is sufficient.
I would like to apply Safe Seal to my plywood subfloor, but have noticed some dampness in the plywood. Will the moisture be able to escape through the Safe Seal?
Yes, but very, very slowly.
How much off-gassing does Safe Seal prevent?
How much formaldehyde is trapped in my plywood subfloor after applying Safe Seal? How long will it take to gas off? Will it gas off slowly over time, or will some gas off initially and the rest be trapped forever?
Applying Safe Seal will have a flushing affect on the plywood, releasing some of the formaldehyde. Once Safe Seal has cured, those emissions will be contained and trapped under the sealer.

AFM NATURAL PAINT FAQS
Does "Zero VOC" mean paint is healthy? Zero VOC does not mean zero emissions. This is because the government allows the use of many chemicals that are V.O.C.’s (Volatile Organic Compounds), but do not cause smog. These are called "exempt compounds" that allow the product to be marketed as "Zero VOC". It is important to note that government regulation of VOCs is not based on toxicity or health, but on the fact that some VOCs react with nitrous oxides and ultra violet light to form low-level ozone, or smog. If the VOCs do not cause this type of reaction, the government isn't concerned if they are toxic or not, therefore exempting them from the VOC calculation.
What makes AFM paints different from other paints that are marketed as healthy paints? It is not enough to simply take regular paint and remove the VOC so that you have a product that can be marketed as environmentally sound. To make an environmental paint that works from a health and reduced toxicity standpoint, you have to build it from the ground up. This is what AFM has been doing for over 20 years. It is why AFM regular paints, which have low VOC, are well tolerated - even by people who are chemically sensitive. Since the introduction of "Zero VOC" paints by the multi-billion dollar paint companies, AFM has received many calls and letters from people who have used those paints, only to find that something in the paint is making them sick. Most of the time, these people end up repainting with AFM Safecoat paint as a solution.
AFM goes far beyond VOC issues in its formulation process. One key reason for the price difference between AFM non-toxic paint and other manufacturers' paint is AFM's use of high quality, refined resins and raw materials to prevent the residual chemical compounds that off-gas and cause problems for people with allergies or sensitivities. AFM products not only contain no formaldehyde, but no formaldehyde precursors as well.
