Answer This Question

Hi Jcraft, the purpose of the White-Seal 5 Gal. Acrylic Elastomeric White Reflective Roof Sealer is to be used as a roof sealer. In your case for the block wall in a basement you could use the Dry-Coat which is ideal to use as a waterproofing paint or sealant. Waterproofs concrete, brick, basements, concrete blocks, stucco, foundations, retaining walls, water ponds, suitable to use above or below grade.

        Hi Gary, we have not tried it , so I cannot recommend it. I know that you can use on wood, but I don't know it's reaction if sea water is getting wet all the time.

                If applied to asphalt shingle roof, does the same warranty apply?
                ByOct 18, 2024
                1 Answer | 
                Answer This Question

                Hi HankT, currently I would say yes, that the same White-Seal warranty applies. I would like to remind customers that with any application of any roof coating will void any warranty they have on their shingle roof. Finally, I would like to make clear that putting elastomeric roof coatings on a shingle roof with an attic with poor ventilation could trap moisture which may damage their roof by rusting nails and rotting wood in their roof.

                  Coverage of Lanco White-Seal 5 Gal
                  I don't know what kind of surface the makers used this on to conclude that a gallon would cover 50 sq ft. I applied it to the roof of my metal 16 x 10 storage shed as thick as I could with a roller. I have applied 500 sq ft (numerous coats) and still have a half of the 5 gal bucket left. I figure a gallon covered about 200 sq ft. If I had known this, I would have just bought 2 gallons.

                  Hi RonB, the manufacturer's recommended coverage is 50 sq.ft. @15 dry mils, 33 wet mils. This is to be able to aquire an optimal finish.

                    highly recommend
                    So far have used 20 gallons for 850 sq ft flat roof. 250 sq ft per pail is realistic. The roof’s temperature has substantially dropped and hence dropped the attic’s temperature. I’m already noticing the AC not coming on as often. Return on investment will be achieved in a short time. Will be buying more to complete the entire roof.

                      Arrived damaged
                      It was delivered with the contents outside the box and a lot on the inside of the box. I guess the FedEx driver didn’t like that I ordered it through the mail )instead of buying it from the store the can is so damaged that there’s no way a simple drop did this much damage the problem is the store doesn’t sell it and anytime I’ve ordered anything to be shipped to store weeks go by with no pick up notification so I have to cancel my orders. Who is going to pay for my gas and time to return it?

                        Re-coat camper roof
                        Covered a camper top with 2 coats. Goes on with a long nap paint roller. Coats well, even, dries pretty quick. Coat in morning, low humidity. Re-coat in 24hrs. Use a thermal temperature gun, do not apply over 120f roof temp. And dont apply late in day as humidity picks back up. Good product.

                        Used on South Florida Mobile home.
                        Apply 3 pails on a mobile home in South Florida... went on with no problems and adhere to the existing shingles well. Heavy rains fell recently, no leaks.
