Article: Mark where you will drill in both with a permanent marker. The spots you mark are the areas you plan to concrete the concrete and wood with the hammer-set concrete fasteners. This will keep your drill holes precise so your fasteners will fit securely into the wood and concrete. You will need hammer-set concrete fasteners to connect the wood and concrete, which you can get online or from most home improvement stores. Drill a hole into the concrete approximately 1⁄4 inch (0.64 cm) deeper than your concrete fastener. When you're finished drilling, blow any remaining concrete dust out of the hole with a small vacuum.  Take all necessary safety precautions while using a drill, and put on safety goggles and professional-grade earmuffs beforehand. In a pinch, you can also use a syringe blower to remove the dust. Using your screw markings as guides, align the wood with the concrete object and drill through the wood into the drilled concrete hole. This will help you make sure that the holes are aligned. Unlike the concrete, where you only have to drill 1⁄4 inch (0.64 cm) deeper than the fastener's length, you should drill completely through the wood. Keeping the wood and concrete holes aligned, position the fastener into the hole and hammer it through. After driving it through the hole, the concrete fastener should expand at the back and wedge itself tightly into the concrete.

Problem: Article: In the morning, a water rinse will suffice for most skin types. Use a mild, gentle cleanser and lukewarm to wash your face every evening. Gently pat your face dry with a clean washcloth. Avoid scrubbing your face dry, which can damage your skin.  If you have problems with acne, consider washing with a product that contains salicylic acid or benzoyl peroxide to manage it. If you wear makeup, remember to always remove it every night. Gently dab at the inner corners of your eyes with a dampened washcloth to remove any debris. After cleansing, moisturize your face. Use a moisturizer that contains a minimum of SPF15 sunscreen to protect your skin from sun damage. Choose a moisturizer that matches your skin type – moisturizer products usually cater to oily, dry or combination skin.  After each shower, apply lotion to your body to avoid cracked skin. Pay special attention to the knees and elbows, which tend to get very dry. Tweeze any stray eyebrows that you see, especially in between your brows. If you shave your face, do it carefully. Always use shaving cream, which protects and lubricates your face. Use a sharp razor that has no debris lodged between the blades. Always shave in the same direction your facial hair grows.  For those who don’t shave their face, inspect the hair above your upper lip – do you see any dark or long fringe? If so, you can manage that by bleaching the hair or removing it entirely with a depilatory. Before you leave the house, check to make sure your nasal passages are clear. Always blow your nose when you get out of the shower. The warm water of the shower will loosen any fluid or mucus that might be trapped in your sinuses, making post-shower the ideal time to flush them out.  If you’ve recently been ill or if you have allergies, consider flushing out your sinuses with a saline solution using a neti pot.  Avoid picking your nose.
Summary: Wash your face twice per day. Apply moisturizer with sunscreen daily. Manage your facial hair. Check your nasal passages.
