Hi Gran - Thank you for your question! Our Ultra Stain-Blocking Ceiling Paint will cover 250-400 sq. ft. per gallon. Please note that we don't recommend applying this product to interior walls as it won't offer the same durability and scrubability as our Ultra Interior Extra Durable Flat will (https://www.homedepot.com/p/BEHR-ULTRA-1-gal-Ultra-Pure-White-Extra-Durable-Flat-Interior-Paint-Primer-172001/309712684). Our Ultra Interior Extra Durable Flat will also offer the same coverage as our ceiling paint. Best - Sara
Hi Chaz - Thank you for your question! This product can be used on your Lanai ceiling as long as it will not be subjected to dramatic temperature changes throughout the year. If your Lanai will be exposed to drastic hot and color temperatures, we recommend using our Ultra Exterior Flat for your project instead (https://www.homedepot.com/p/BEHR-ULTRA-1-gal-PPU18-08-Painters-White-Flat-Exterior-Paint-and-Primer-in-One-485001/204105590).

Hello Peterphu, Great question. It really has a great chance of still matching after 2 years. It also depends if the walls are constantly cleaned and scrubbed. However, our paints are great in maintaining its color for many years. Best regards, Kevin
