B. Hacker Floor Primer
C. Hacker Floor Underlayments.

PART III EXECUTION

3.1 Condition of Subfloor

A. Subfloor must be structurally sound (L/360), broom cleaned, and free of oil, grease or other contaminants.
B. All cracks and voids should be filled with a quick setting taping compound to prevent leakage.
C. Before installation, General Contractor shall inspect and approve the condition of the subfloor.

3.2 Priming

A. Before installation of the Hacker Sound-Mat, spray the substrate with an approved Hacker Floor Primer (diluted 2:1 with water). Spray the primer just before installation of the Hacker Sound-Mat so that the primer is wet when the mat is rolled onto the substrata.

Note: Hacker Sound-Mat will not bond to dry primer; the primer needs to be wet to ensure the bond.

3.3 Mat Application

A. Hacker Sound-Mat should be rolled up the walls at least 1/4" (approx. 6mm) higher than the pour line to create a sound isolation break between the underlayment and the wall. Tape can be used to hold Hacker Sound-Mat up against the wall. Hacker Sound-Mat must be installed properly so that no underlayment touches the walls, floor, or other objects attached to the subfloor. Tape can be used in the corners and around other obstacles. All seams must be taped.

3.4 Underlayment Application

A. Spray a coat of Hacker Floor Primer (diluted 2:1 with water) at a rate of 400 sq. ft. per gallon over the Hacker Sound-Mata prior to the underlayment application.
B. A 1-1/2" (approx 38mm) mini- mum application of either Firm-Fill 2010, Firm-Fill High Strength, or GYP-Span Radiant must be installed over the Hacker Sound-Mat according to Hacker Specifications (see applicable literature for specifications).
C. The Hacker Sound-mat should be trimmed flush with the Hacker Floor Underlayment after it is set.

APPLICATION NOTES:

Extreme care must be taken when rolling out the hose so that the Hacker Sound-Mat is not torn. Do not wear spiked shoes. Do not use nails to gauge materials depths.
The Hacker Floor Underlayment should be installed with a tight slump to minimize the drying time.
Do not puncture the Hacker Sound- Mat with any metal fasteners or other metal equipment: metal punctures may cause neutralization of Hacker Sound-Mat's acoustical properties.
