I expect to use 32 ounces if I'll be installing 50 ft² of MLV or more.
Seal Seams in MLV and Bond CCF to MLV
HH-66 Vinyl Contact Cement connects CCF to MLV, MLV to MLV (critical), CCF to CCF – any two surfaces of materials with vinyl content. That’s why I have the CCF manufactured with vinyl as one of the polymer components. It’s also why the adhesive on the Velcro Strips I sell is optimized for adhesion to vinyl. When you get right down to it, we’re trying to line our vehicles with vinyl – a material to which very few things will stick.
HH-66 is a contact adhesive that will only bond materials with vinyl content. That means MLV to MLV, CCF (like the material I sell with vinyl content) to CCF and MLV to CCF. You need to coat both surfaces and let them dry until just tacky, 3-5 minutes. Press the two parts together. The bond is more than strong enough to work with immediately. It will achieve its full strength after a few hours.In most cases you won't need to coat the entire surface - tacking in a few spots is usually sufficient.
I expect to use a 32 ounce can with 50 ft² of MLV or more. 8 ounces for less than 50 ft².
