Frequently Asked Questions

1. Can TWP® be painted over?
TWP® 100 Series: YES, but it must be allowed to cure for a minimum of 30 days. TWP® contains a water repellent so an oil based caulking, or oil based primer or paint must be used. IF an oil based primer is used first, a water based paint can be used as a top coat.

2. Can TWP® be tinted?
NO, do not tint the ready mixed colors of TWP®. Variations of color may be achieved by intermixing the colors (except the grays, which can only be intermixed with each other or the clear). TWP® 100 or 500 may be used to lighten any of the standard colors (101, 102, 103, 105, 106, 115, 116, 120, 501, 502, 503, 511, 515, or 516). Do not dilute more than 50% with the 100 or 500, as the clears do not contain UV absorbers, so they lessen color stability, 25% is preferable. TWP® 98 and TWP® 99 are designed for tinting. These are the only TWP® products that will except colorant.

3. Will TWP® stain the caulking/chinking?
YES. If you want the chinking to remain its original color, apply TWP® 100 Series, then chink. Be sure to test the chinking and TWP® for compatibility. If using TWP® 500C Series, you must chink first.

4. Will TWP® protect my deck from scratch marks?
NO, TWP® is a penetrating wood protectant, not a varnish. TWP® does not form a film, therefore it cannot protect wood from scratches.

5. How can I tell if my previously treated wood will accept a coat of TWP®?
After cleaning/power washing, if water beads up on your wood, there is still enough of the old wood treatment remaining to adversely affect penetration of TWP®. A good rule of thumb, if your wood absorbs water, it will absorb TWP®. It is always wise to do a test area when in doubt. Under normal conditions, 6 months of weathering will remove mill glaze and TWP® will penetrate properly. Gemini's Wood Prep will also promote penetration of TWP® into the wood.

6. How long can I store the TWP® I have left over?
TWP® has a shelf life up to 18 months. The original container must be tightly resealed and stored in an area where temperatures do not drop below 50 degrees F.

7. Can I add a pesticide to TWP® to help protect my log home from insects?
NO, If your logs were not treated by the log home supplier, contact your supplier for their recommendations on how and what treatment to use, before you apply TWP®.
