Deck Paint

I have a veranda with a concrete bridge. The case is not weatherproof. It is a screening room with a roof. Thus, humidity and temperature are a problem in the summer. The paint never seems to adhere well, whatever the precautions taken to prepare the area and ensure that the paint is applied in conditions of low humidity in warmer temperatures. Any suggestions would be greatly appreciated. I am in the northeast United States and have access to Home Depot and Lowe's, and other specialty retailers.

Make sure the surface is clean. But perhaps it is time to move to a different painting if you encounter problems both.

An epoxy surface seems to be very well suited to your needs. Rustoleum makes a kit to do the job.

They sell a great epoxy floor paint designed for garages. It seems that maybe what you need.

Prep. prep. prep.

It is 90% of employment and the main factor in the finished result.

Epoxies are good. But they are expensive and can be difficult to work with especially if you are inexperienced. In addition, the epoxy will fail against water seeping through the cement. I suggest you make sure the surface is totally free of any loose paint, dust and debris. You may need to burn the surface with hydrochloric acid (available at all paint stores and hardware) to give a "tooth". This allows the new paint to grasp. Plan on using 2 layers of alkyd (oil base), preferably a polyurethane flooring. Dilute the first layer of about 25% with mineral spirits, wait a whole day and give a second coat full strength. I have done this technique many times without fault. Good luck!

Wiz sounds right. But after the acid stage and before the step of painting, I wonder if you need a primer. Perhaps Wiz meet again.

As with any paint job preparation work is the most important step. Step 1: Remove all peeling and blistering paint. 2 stept clean surface with shop-vac. Step 3 etch surface rub with a stiff brush muratic acid (no eye protection Foget). Step 4: Rinse the surface. Step 5: Repeat step 2 to remove excess water. let dry completely. Step 6: Start good primer sealer if the surface is porous, I recommend two coats of sealer primer. let dry completely in step 7: apply a paint porch that is recommended for concrete. Over-Nite dry then apply a second coat. Note: there are very good latex primer and paint on the market there is no reason to endanger health or the environment with solvent-based products. As with anything using quality materials is always a good idea!
