CPR Frequently Asked Questions:


 "How do I get rid of mold/mildew on the surface of my wood?" 

Try these methods first:

1) Apply CPR in the brightener strength (4 parts water to 1 part CPR).  Apply according to directions. Thoroughly rinse, very thoroughly. 

2) Or, apply fresh bleach in a 4 parts water to 1 part bleach solution.  Allow to sit no more than 10 minutes, then thoroughly rinse, very thoroughly.

If those don’t work, chat with us or call us. There may be other issues at play that need to be considered.

In all cases where mold/mildew is a problem, be sure to use an extra mildewcide in any future coats of stain. 


"How do I maintain my chinking and caulking?"

When installed properly according to the instructions, chinking and caulking don’t take much in the way of maintenance.  It is always good practice to check for any loss of adhesion or center tearing so that you can repair it immediately, preventing any water and insect infiltration in those areas.  You may also want to periodically clean the surface for appearance’s sake. You can clean your chinking and caulking lines with soap and water.  Stubborn areas can be scrubbed with a nylon brush and water.


"How should I prep my home that already has stain on it?"

That will depend on what is on there and what condition it’s in.  A light pressure wash may be all that’s needed if everything is in good shape.  If there are significant areas of peeling stain, bare and/or gray wood, etc., a vigorous power wash or media blast will be needed.


"My house looks good, except on one side it looks weathered.  I like the weathered look on my home, but someone told me it was rotting." 

That “weathered” look – gray and/or yellowed wood – is really the erosion of the wood.  Freshly-cut, debarked wood is white to very light yellow in color.  As wood starts to weather, its color shifts from a deep golden color, to gray, and can then become almost black in color in the latest stages of weathering. The wood surface is deteriorating due to UV radiation, oxidation, and water damage.  Actual wood fibers are weakening and detaching from the main body of the log.  It is best to remove all of this weathered wood and then re-stain. Otherwise, several major problems are likely to occur.  Don't be lazy, do it right.
