How Many Tubes of Sealant Are Needed to Complete Installation of LaSalle Bristol XTRM Roof Membrane


How many tubes of self-leveling and non-sag sealant would you need for a 35foot fifth wheel with two slides, one 16foot and the other 8?


Expert Reply:

A typical 10 oz tube of sealant will cover approximately 50 linear feet but this can vary depending on the bead size. I recommend measuring all the areas of your trailer that will require sealing so you can determine how many tubes your project will require.

A convenient option to consider is the LaSalle Bristol XTRM RV Roof Installation Kit # 3442703414KIT. Not only is this a more economical option than buying everything separately, this kit will take most of the measuring and guessing game out. The kit includes a 2-gallon container of EXP90 adhesive, six 10-oz cartridges (300 linear feet) of XTRM 100 self-leveling sealant, and two rolls of butyl tape. This is perfect to install the LaSalle Bristol XTRM Roof Membrane - 35' Long # 3441700534142711435 you referenced.

Aside from some non-sag sealant like # 344270341437-1 for the vertical surfaces (which you still need to measure), this kit includes everything you need to install the LaSalle Bristol XTRM Roof Membrane # 3441700534142711435 which you referenced.
