Questions & Answers
does it seal while not being full cured
Sherrycox, the short answer is yes. Henry 208 Wet Patch instantly stops a leak when applied. It will stay a little soft for about 30 days as the solvents in it slowly evaporate out.
Can Henry's be put on a rv roof
John, for an RV roof we only recommend using Henry 884 or Henry 885 TropiCool 100% Silicone Repair Sealant. RV roofs are usually a rubber membrane or a TPO type of membrane that Henry 208 would not be compatible with.
Does this product get hard after drying. Or does it ever get dry?
In order to perform properly in wet conditions, this product never hardens; it is continually soft.
Roofleaks, Henry 208 Wet Patch will harden as it cures. It will take about 30 days or so to cure properly as the product slowly releases the solvents in the system.
How much coverage for 3.3 gallon size?
Larry, the coverage rate of Henry 208 Wet Patch is approximately 12 square feet per gallon applied at 1/8" thick.
What do you apply this with?
You will need a trowel or a putty knife to apply Henry 208.
Can i use this to seal the cracks at the grade level where the house wall meets the sidewalk concrete slab?
WannaBeDIY, for a repair on two dissimilar surfaces like you are describing we would recommend that you use Henry 900 Flashing and Construction Sealant. Henry 900 is made to adhere to many types of surfaces and will stay flexible for many years. After Henry 900 cures it can also be painted.
What is a curing time on this material?
Carlos, for Henry 208 Wet Patch to completely cure it will take 30 days. Once cured you can coat over it with a Henry Roof Coating to extend the repair life.
I’ve accidentally applied this to a small tear on a rubber roof membrane. I thought I purchased 209 XR and was in a hurry.. what can be done!? Please help.
You can scrape off the Henry 208 with a plastic putty knife, so you don't tear the membrane and use a waterless cleaner like GoJo or water-based Goof-Off to remove the excess Henry 208.
