Water repellent formulations consisting of five paraffin wax emulsions, three polyethylene wax emulsions, two polybutadiene resin emulsions, a polyester emulsion, and a ß-pinene polymer emulsion were subjected to water repellency tests on radiata pine sapwood. With one exception, the parafin wax emulsions were more effective water repellents than the alternative formulations and one of the paraffin wax emulsions (Paracol 800A) was selected for inclusion in laboratory antisapstain tests. The results showed there was no improvement in fungicidal effectiveness of NaPCP/borax, Busan 1009 (Buckman Laboratories), or Mitrol PQ375 (Kenogard) with addition of this water repellent.
