1.4.1 Chemical Resistance
Monolithic surfacings and polymer concretes mirror imaget he chemical
resistance of their mortara nd grout counterparts. Refer to corrosion tables
previously presented and Table1.10 whichfollows.
Table 1.10 provides comparative chemical resistance for the most popular
resins used as monolithic surfacings and polymer concrete. Those systems
without chemical-resistant mortarand grout counterparts area sf ollows:
1. Acrylic
2. Urethane, rigid and flexible
Acrylic monolithic surfacing and polymer concretes arei nstalled in
thicknesses of 1/8 to 1/2 in.( 3–13 mm) and 1/2 in. (13 mm) and greater,
