AlertMat Detectable Warnings Installation

Prior To Installation:

1. Place appropriate barriers and/or warnings to pedestrians
or vehicles as directed by your organization. Remember, safety first!

2. Determine the correct location for installation of the AlertMat

detectable warning as required by the ADA and your governing authority.

Surface Preparation and Mat Positioning:

3. Surface must be completely dry with no precipitation at least
24 hours prior to installation.

4. It is recommended that the adhesive be applied at temperatures
over 40 F (4 C).

5. Surfaces with newly poured concrete must be fully cured.

6. Sweep the installation surface clean. For best results, the
surface should be free of oils, sealants, grease, vegetation, sand,
soil, dust and loose aggregate. Patch any holes or cracks as necessary
prior to installation.

7. Place the mat in position on the installation surface and adjust
fit until satisfied.

8. Mark the concrete at each mat corner. These marks will be used
later to reposition the mat after adhesive has been applied.

illustration 8

9. Using either soapstone, pencil or masking tape, outline the
concrete around the perimeter of the mat at least 1/4″ from
the mat’s edge. Outline this area on all sides and for the complete
length and width of the mat to ensure the area beneath the mat receives
an adequate amount of adhesive.

10. Remove the mat and place it dome-side down away from the installation
surface. Clean back of mat and make sure mat and walkway are free
of dirt and dust.

Applying Adhesive:
(Caution: As with any chemical, read and follow directions on container)

11. Using a short nap paint roller and pan, apply a thin, uniform
coat of adhesive to the back of the mat and the installation surface.
Cover both surfaces completely and evenly. Keep adhesive within
mat outline.

See illustration 11

12. Allow adhesive to dry until neither surface is tacky to touch
(approx. 10-15 minutes, depending on the weather). Adhesive should
be dry to the touch, but tacky. (Note: Do not wait more than 30
minutes)

Placing the Mat:
13. AlertMat adhesive bonds instantly, so pieces must be positioned
accurately as contact is made! Using the marked corners from (#8
above), align the mat’s corners with the marks on the concrete.

See illustration 13

14. Slowly and carefully press the mat down from one end to the
other, working air bubbles out from the center to the outer edges.
Make sure the mat falls within the glued outline. Avoid stretching
the mat and do not reposition the mat once adhesive-coated surfaces
have come in contact. If adhesive is disturbed, apply a new coat
to disturbed area.
See illustration 14

15. When mat is in place, walk on the mat from the center to the
edges, along the domes, between the domes and along the beveled
edges to assure solid contact.

Installing Anchors:
16. AlertMat comes with pre-drilled anchor templates to ease installation!
Using a hammer drill, drill a 1- 3/4″ deep by 3/16″ diameter
hole through each anchor template in the perimeter of the mat. For
best results, holes should be perpendicular to the concrete surface.
Remove concrete dust from hole and mat with broom.

See illustration 16

17. Insert an AlertMat anchor into each hole and hammer into position.
Do not over tighten. Anchors should not be driven into the mat or
cause compression or distortion of the mat material. Never place
anchors in domes.
See illustration 17

Edge Sealer:
18. Complete the AlertMat installation by applying a small bead
of sealant along the outer edges of the mat.

19. AlertMat detectable warnings can be walked on immediately after
installation. Adhesive should be completely cured in about 72 hours.

Notice: Use only adhesive, sealer and anchors provided with AlertMat.
