Howdy MSContractors,

 

 

Welcome to the Home Depot Community for starters. This is the place where we exchange ideas, expertise, and opinions on all things "home improvement".

 

Here is the simple steps to prepping for painting a porch:

 

1) Compute the square footage of your porch and purchase enough paint to cover it -- labels will tell you how many square feet the container should cover. Before beginning to paint, mix your paint in a large container you can seal. Mixing cans of paint blends any differences in paint lots to a uniform tint for your floor.

 

2) Scrub the floor with a solution of trisodium phosphate and water to loosen dirt and grime. Rinse the porch well with plain water. I like to use a power-washer myself to get as much loose paint off as possible.

 

3) Put on a respirator, scrape loose and peeling paint and sand bare wood and paint margins smooth. If there are more than a few spots, you may wish to sand the entire porch down to an intact paint layer or bare wood. Rough up smooth surfaces with sandpaper or steel wool and sweep the porch clean.

 

4) Mask walls, balusters and posts on and around the floor with low-tack painter’s tape when the floor is completely dry. Smooth the side of the painter's tape that abuts the floor with a plastic putty knife to seal the edge against paint seepage.

 

5) Apply a layer of exterior primer labeled for use on floors, cutting in around edges with a small brush and painting large areas with a broad brush or roller with a medium nap. Work from the corner -- or corners -- to the front steps. Use the best quality exterior floor primer you can afford, but put only latex paint over latex. You may use alkyd or latex over old oil-based paints.

 

6) Tie a string across the front steps and hang a sign on it to direct visitors to an alternate exit and then paint exposed board ends. Allow the primer to dry completely, usually between 24 and 48 hours, before painting.

 

7) Lay on a first coat of exterior floor or deck paint over the primer, again cutting in around the perimeter with a small brush and painting large areas with a roller or wide brush. Apply paint in two directions, finishing by brushing along the grain of the wood. Paint the exposed board ends and replace the sign across the front of the porch and allow the first coat to dry, again for 24 to 48 hours.

 

8) Apply a second coat if necessary. A complete prime coat may make a second coat unnecessary.

 

9) Check the directions on the paint can for dry time needed before walking on the floor.

MSContractors,

 

DeckOver is a self-priming solid hide deck stain. Two coats is recommended. Where heavy cracking of the grain is encountered, spot primeing of such areas will aid in sealing them off.

 

DeckOver can be applied over existing deck coatings, but be aware that the adhesion of the DeckOver is only as good as that which it is going over. If the old finish lets go, The DeckOver will go also. To this end, be sure that the old finish is sound, any loose and peeling paint should be scraped and feathered. As with any coating application, the deck should be clean and free of dirt, mildew and algae.

 

DeckOver is applied with normal brushes and rollers in a manner similar to other solid hide stains.. Behr has an instructional video on its website: www.behr.com. There are other vdeos concerning DeckOver on You Tube.

 

Hope this has answered your questions.
