PIERI® GEL-ETCH is a light, controlled etching acid gel in which the acid is blended in gel form to help control fumes and aid in adhesion to vertical surfaces. Coverage: approximately 90-180 ft2/gal (2.2-4.4 m2/L), depending on etch desired.
PIERI® GEL-ETCH is ideal for simulated limestone or for field patchwork, including vertical surfaces. The light etch will preserve formwork details and will not interfere with waterproofing sealers or other coatings.
Directions for Use
Pre-wet area to be treated to a saturated surface dry condition. Mix PIERI ®GEL-ETCH thoroughly and apply with a acid resistant brush over the section to be treated. When bubbling stops, rinse completely, or apply a second coat in order to provide a more overall appearance. Finally, rinse thoroughly using high pressure water if available.
Note the etch depth will be a function of dwell time and number of applications.
