As with any quality lining system, the long term in-place performance of Marseal corrosion resistant linings depends upon following proper installation techniques. |
Specific application requirements may vary from project to project. This section provides general information only regarding the installation of Marseal linings, it is not intended as an application guide. The applicator is responsible to determine application techniques to suit specific project conditions.
Questions regarding installation recommendations and requirements for specific projects may be directed to our Technical Department. Call toll-free 888-276-1400.
The unique properties of Marseal flexible sheet membrane combined with hot-air welded seam construction provide absolute security in containment applications.

Surface Preparation
Start all Marseal installations with smooth, clean, dry substrate, free of large voids, loose aggregate, and sharp projections. Blasting is not required if the surface is clean and smooth.
|
|
|
|
|
Priming
Priming is required to improve the bond strength of Marseal to the substrate. Marseal Primer should be applied to all surfaces to be lined at 150 to 200 square feet per gallon, using a roller or brush. Allow the primer to dry to the touch before applying the lining.

Installing Wall Sheets
Measure and pre-cut Marseal Lining into appropriate wall and floor length before the installation starts. Apply lining to the wall area first, allowing 6" to extend over the top of the wall. Lay each adjacent sheet with a 3" side lap (fully cover lay line to ensure proper lap) until returning to starting sheet.

|
Rolling Wall Sheets
After each sheet is applied, use wall roller to tightly adhere sheet to primed surface.
|
|
|
|
|
Installing Floor Sheets
Apply floor sheets in similar fashion to walls, overlapping sides by 3" (covering lay line on previous sheet) until entire floor is covered.
|
|
|
|
|
|
Welding Seams
After all lining is applied, weld all side laps with a hot air welder, followed immediately with a 2" roller to fuse sheets together.
|
|
|
|
|
Installing Sealing Strip
Install Marseal Sealing Strip over all end laps and corner seams using a hot air welder and 2" roller.
