Q: Can I paint over old paint on my porch?

• <div><p>Whether you can paint over your existing paint depends on what&rsquo;s on there. Most of the time, you&rsquo;ll want to sand down or scrape off the paint that&rsquo;s currently coating your surface. Epoxy paint, for example, won&rsquo;t let new paint stick to the surface. Latex paint is more forgiving and will accept a new coat, but a primer is recommended if you&rsquo;re switching colors.</p></div>

Q: How do you keep pressure-treated wood from rotting?

• <div><p>Various kinds of substances and deck preservatives act as protective coatings for wood to prevent rot, which is caused by water getting into the wood and creating cracks and splits. Stains, paints, and sealants are the three best options to protect your wood, but there are also oils, varnishes, and waxes available. You&rsquo;ll need to reapply sealant at least once per year, and you should <a href="https://www.angi.com/articles/how-often-should-i-inspect-my-deck.htm">inspect your wood deck</a> regularly to look for signs of damage or general wear and tear.</p></div>

Q: What should you not use on a composite deck?

• <div><p>Avoid using cleaning products that are abrasive or contain bleach or acidic components on composite decking to avoid discoloration. Early-generation Trex decking isn&rsquo;t designed to handle pressure washer cleaning&mdash;and if you use them on second-generation boards, always use a low setting to avoid the risk of damage that can risk voiding your warranty. </p></div>

Q: Can you waterproof all wood?

• <div><p>Yes, you can waterproof any wood that has not already been treated. A good way to test this is to splash some water on it. If the water starts to bead up, the wood is treated and most likely doesn&rsquo;t need another coating.</p></div>

Q: Does wood stain go bad?

• <div><p>Wood stain does go bad, but it will last in the can for between three and six years, provided you use proper storage techniques. Storing wood stain in open containers or in extremely low or high temperatures will cause your wood stain to become unusable much more quickly. Water- and latex-based wood stains typically last for just two to four years, while oil-based wood stains can last for three to six years. </p></div>

"Very well, Eddie and his crew did an excellent job painting the interior of our home. They completed the work on schedule, cleaned up everyday and were careful moving household items. Eddie also did an excellent job sanding and staining our front door when other companies said to just paint the door, that it was too much trouble to re-stain. Eddie also guarantees his work and works hard to make sure you are happy with the final results when work is completed."
