Surface Preparation
Surface must be completely dry and in sound
condition. All surfaces must be clean and free of
contaminants such as form and release agents, dirt,
grease, mildew, oil, rust, chalk, efflorescence, organic
growth, mildew and non-adherent material. Gloss
finishes should be sanded or de-glossed. Feather sand
rough edges and spot prime bare areas. Any
deteriorated or failed sealant and/or patching
compound should be removed and replaced. Fill cracks
and primed nail holes with Lanco
®
Rain-Shield
TM
Elastomeric Crack Filler. Apply sealants or patching
compounds over a primed surface and at a safe level of
pH.
CONCRETE & MASONRY SURFACES: Allow a minimum
of three (3) days of cure time for new masonry or hot
stucco, a seven (7) day cure time for poured in place
concrete or a safe pH level below 8.5 prior to
application of product. Coatings have a greater
resistance against failure when applied to a surface with
a lower alkaline level (below 8.5). Clean substrate to
remove all form and release agents, dirt, dust, grease
and any foreign contaminants. High pH (between 9 and
13) should be primed with LANCO
®
Rain-Shield
TM
High
pH Primer or LANCO
®
Rain-Shield
TM
Clear Acrylic
PLASTER SURFACES: Plaster nibs should be scraped
and sanded smooth. Cracks should be filled with
spackling compound and let dry two hours before
painting. No paint or sealer should be applied on
plaster when the moisture content exceeds 8%, as
determined by a reliable electronic moisture meter.
GYPSUM WALLBOARD SURFACES: Tape and smooth
joints with spackling compound and let dry for two
hours. Nail heads should be sanded smooth and dusted.
WOOD: Nails should be set and filled with spackling
compound. Sanded smooth and dust free of
contaminants. Knots holes need to be spot primed with
a stain blocking primer to avoid bleeding.
GALVANIZED STEEL AND ALUMINUM: Remove rust
by hand or power tool cleaning (SSPC-SP 2-63 or SP 3-
63) and prime. LANCO
®
Ultra Durex Primer™ or LANCO
®
Metal Master Primer™ may be required to superior
protection and adhesion.
PREVIOSLY PAINTED SURFACES:
SURFACES IN GOOD CONDITION: Sand any glossy areas
by brush blasting (SSPC-SP 7-63) and dust clean.
SURFACES IN POOR CONDITION: If paint is old, loose,
peeling or badly weathered, repair and clean surface by
sanding, brush blasting (SSPC-SP 7-63) or other
methods in order to provide a sound surface. Apply a
full coat of primer as recommended.
