Q: [header] How to paint masonry walls [title] Remove any flaked or peeling paint from the masonry. [step] If the wall has already been painted, you need to remove any old paint that is loose, peeling, or flaking away. On an exterior wall, this is most efficiently done with a sandblaster. <sep> (A) New paint must be removed from the wall first, gently scraping around the edges with a rat-tail tail reciprocating scraper. This is most often done on exterior paint walls that are still meant to protect it from debris. (B) In areas where a sandblaster would be too messy and cumbersome, loose paint can be removed with a stiff wire brush and a paint scraper. [substeps] Failing to remove loose and peeling paint can result in the paint flakes mixing in with your fresh coat of paint and marring the finish. (C) [substeps] Make sure to turn off the water. Do not flush the wall down the drain. (D) If there is a paint-resistant paint strip still clinging to the wall, it may be painted to the wall as well, but not directly under it. [substeps] Using a sandblaster may be wise, but if the paint is not taking off, it may be better to start by sanding lightly.

Q: [header] How to get super glue off skin [title] Select the right nail polish remover. [step] Acetone is the substance in nail polish remover that helps dissolve superglue for removal. You need an acetone-based remover in order for this method to be successful. <sep> (A) Too much acetone can cause further damage and discoloration, so look for an acetone-based remover that contains benzoyl peroxide. This form of treatment works best on especially dark blemishes, but you can also use this method for lighter polishes. (B) For the traditional " acetone-based " nail polish remover, create a thick, grainy layer on both sides of each nail. [substeps] Alternatively, you can soak a cotton ball in acetone and dab it up against the entire surface of each toenail. (C) [substeps] Check the ingredients label of your nail polish remover. Acetone should be listed here, usually towards the top of the list. (D) It may be injected directly into the concealer border or you can buy it online. You can use a nail art brush to apply the acetone, or dip a cotton ball in acetone-based remover and gently rub your skin with the cotton ball.

Q: [header] How to put together your own pretty committee [title] Find the perfect girls to be your exclusive group of friends. [step] A good amount of girls is three to six. There should be an alpha, beta, and other loyal chicks. <sep> (A) After you find your perfect girls, befriend them, and invite them to a sleepover. [substeps] Do not have more than six girls in the group; after that, it is not very manageable as a clique. (B) [substeps] Choose the top girls that are a good fit for your position. The alpha girls are out of range from alpha and beta, but really their flaws aside, they are the best girls ever. (C) Unless one is a significant other, such as a friend of a colleague, sit it out until the gossip dies out then break up all together. While this may seem like a long-term goal, this step is necessary to win the clique's respect. (D) Ask them for suggestions and advice on what pair they have in your eyes. There are also a number of alternative group groups, usually the majority of the girls are just vegetarians of small sex group (ie: people living with small children).
