Getting black glue lines on projects? Metal containers like coffee cans can cause this problem, which occurs more often with white glue than with yellow glue. Glues with a pH lower than 7 can absorb iron from the metal, and the dissolved iron can react with certain colored woods to leave black glue lines. Use plastic containers instead.
Rubber slate can be a good choice when re-roofing a Victorian. Made from the same material as car bumpers, rubber slate can last up to 100 years. The slates are flexible, predrilled and calibrated. They can be cut with a knife and installed in any weather conditions. Rubber slate is an ideal product for a steep, complex roof with turrets, valleys, and crickets.
