Article: Even oxygen in the air can lead to rust on your razor blade. Coating it in oil will provide a barrier between the metal blade and the surrounding air. Choose from a variety of household oils, including olive oil, baby oil, vegetable oil or mineral oil. Ensure the blade is completely coated. Don't rub the film off or it will defeat the exercise. If you prefer, you can also pour some of your chosen oil into a small saucer. After you're sure the blade is completely coated, just remove the razor and set it down to dry on a paper towel.

Prevent your razor blade from rusting by coating it in oil. Pour some oil on a rag or cotton ball and wipe it across your razor blade. Soak the razor in a bath of oil.
Article: Masonry primers will adhere to the stone walls better and provide more durability than general primers. Masonry primers also protect the stone from water damage. With the lid on, vigorously shake the primer container to mix the contents.  Follow the instructions for your specific masonry primer. If no directions were supplied, follow these general guidelines for applying masonry primer to stone walls.  Use a wide nylon/polyester brush to apply the primer. The brush should be between 2 and 3 inches (5 and 7.6 cm). Avoid rollers when painting stone basement walls because the roller won't get the paint into the small uneven surfaces of the stone. The rugged stone surface also could tear a roller cover. Cut in a 2- to 3-inch (5- to 7.6-cm) border around the top, bottom and sides of the stone walls. Start by applying masonry primer in 1 corner and continue along the edge of the wall. Paint the masonry primer onto the stone walls in 4-foot by 2-foot (1.2-m by .6-m) sections. As you apply the primer, overlap into the previously applied and cut in areas for consistent coverage. For best results, let the masonry primer dry for a minimum of 8 hours.

Select a primer created specifically for masonry. Mix the masonry primer. Pour the masonry primer into a bucket or paint tray. Apply the primer to the stone walls. Allow the primer to dry.
Article: Swelling is one of the primary signs of a sprained finger. If your finger was bent uncomfortably far to one side or the other, the ligaments connected to the finger’s bones may be stretched or torn. The tendons will swell on the side opposite the way in which the finger was bent. So, if your finger was forced too far to the left, look for swelling on the right side of the finger. Notice if the soft underside of your finger seems puffier than usual. If so, this is a sign that the finger has been sprained and that the ligaments near the base of your finger have been stretched or torn. If you’re not sure whether or not the finger is swollen, compare it with the corresponding finger on your other hand. Along with swelling, the most notable sign of a sprained finger is red discoloration. Inspect the sides and bottom of your finger. If the finger is more red than the surrounding fingers, it’s likely sprained.  The degree of redness will vary with the severity of the sprain. So, if your finger is lightly sprained, the skin covering the sprained tendon may be slightly pink. If the sprain is severe, a large portion of the finger may be notably bright red.

Look for swelling on the sides of your finger if it was bent sideways. Inspect the bottom of your finger if the finger was bent backwards. See if parts of your finger have turned a shade of red.
