Teak

Teak is an oily, grainy, and porous wood that does not easily take to varnish.  It must be properly sealed before varnishing.  These notes are for a brushed applictation.  The application is done in three steps over 4 or more days: 

• Day 1: 2 seal coats
• Days 2 & 3: 8 build coats
• Day 4: 3 finish coats

Sealing – 2 Coats

MaxGlass is used for sealing as it is more flexible, has less solids and penetrates better.  It fills the grain. Apply two coats with a 1 hour recoat time.  The procedure is as follows:

1.       Coarse sand the teak with 80 grit sandpaper.

2.       Use MEK or Acetone to wipe down[2].  The brown oils will come out of the wood.  Repeat this 4 or 5 times until the oils stop showing up on the rag.

3.       Thin MaxGlass 60% to 100% with 871 (slow thinner) for first seal coat application.

4.       Thin MaxGlass 60% with 871 (slow thinner) for second seal coat application.  Wait about 2 hours for the second seal coat.

5.       Bubbles may show on the surface from internal outgassing.

6.       Let dry and sand with 180 grit.  Remove all dust using tack cloths.

7.       Change any masking tape.[3]

FastGlass 2-Component High-Build Varnish – 8 Coats

FastGlass has higher solids and dries faster.  The point of FastGlass is to build up a base which is sanded back to a perfectly flat and smooth surface.  This is done over two days, applying 4 coats per day.  Heavy sanding at the end of both days produces the nice, smooth base to which the UV topcoat is applied.  It is unfortunate to sand away so much of this expensive product, but that is its purpose.  The application procedure is as follows:

1.       Thin 10-20% with appropriate thinner depending on weather and wind conditions.

2.       Recoat as soon as it is touch dry.  Add thinner as necessary to keep the consistency constant.

3.       Do 4 coats in one day.

4.       Sand with 220 grit after 4 coats have been applied.

5.       Change any masking tape.

6.       Add 4 more coats the next day.  Make sure to remove all dust with tack cloths before re-coating.

7.       Sand with 220.  Nice and smooth.  Remove all dust using tack cloths.

MaxGlass 2-Component UV Varnish – 3 Coats

1.       Make sure surface is clean, dry, dust-free. 

2.       Thin 10-20% with appropriate thinner depending on weather and wind conditions.

3.       Apply 2 coats.  MaxGlass should  be touch dry in 30 minutes.  Recoat at touch-dry + 30 minutes.

4.       Light sand with 320.  Remove all dust using tack cloths.  Probably will not need to re-tape.

5.       Apply final coat.  Thin product 25%.

General Notes

• MaxGlass and FastGlass are remarkably forgiving of temperature, wind, and humidity – far more than many other products.  However it is best to apply your final coat at least 1 hour before sundown. 
• Mix the two-part varnigh together first, the add thinner and mix thoroughly.  Failure to mix any 2-part compound can result in undesirable results.  We have had “fish-eyes” result from poor mixing.
• Make sure temperature of all ingredients is the same.  It is best to let the Stoppani equilibrate to room temperature before use. 
• Note that if the day is very hot use the less volatile thinner, #817.
• This product seems to work best above 65°F.
