XIM UMA Primer

XIM UMA® Advanced Technology Primer/Sealer/Bonder Primer is a fast drying, water-based bonding agent that has both primer and adhesive-like properties. It provides excellent adhesion to hardto-paint surfaces even in high humidity conditions. Advanced Technology UMA Brand will form a hard film when fully cured. UMA Brand can be used for indoor and outdoor applications and can be topcoated with latex, oil-based alkyds, lacquers, epoxies and urethanes.

Recommended For

UMA Brand is suitable for use on wood, metal, most plastics, fiberglass, Formica®, tile porcelain, glazed block, and glass. It is also suitable for use on aluminum preceded by a solvent wipe. It is also recommended for Kynar® and silicone polyester siding. When priming Kynar® or silicone polyester siding, apply a test patch in two different areas to ensure adhesion is acceptable.

Not Recommended For

UMA Brand is not recommended for tubs, sinks and shower areas where continuous hot, soapy water contact occurs. Not recommended for use on polypropylene or polyethylene materials. Not recommended for below grade applications. For extra corrosion protection on iron or steel, use XIM360 NT Rust Inhibiting Primer. On extremely porous surfaces or severe staining types of wood, additional coats of Advanced Technology UMA Brand may be required.

Surface Preparation

Surfaces must be clean, dry, sound, and free of dust, dirt, wax, polish, grease, oil, chalk, loose paint and other contaminants. The surface should be sound and stable. Clean with a strong detergent, rinse and allow to thoroughly dry. For hard, glossy surfaces, including pre-finished siding, clean with XIM GON™ or xylene. Do not use solvents that leave an oily residue such as mineral spirits or turpentine. Scuff sand hard, glossy surfaces for maximum adhesion. Mold and mildewed surfaces should be cleaned with bleach, then thoroughly rinsed with clean water and allowed to dry.

Application

Use in a well ventilated area when temperatures are between 40-100°F (4-38°C). It can be applied in high humidity conditions up to 90% relative humidity. Thoroughly mix to ensure any settled pigment is re-dispersed before using. If thinning is desired, use XIM Latex X-Tender at 2 ounces per gallon. Apply with a synthetic (nylon, polyester or blend) bristle brush, ¼” synthetic roller, conventional or airless spray. Follow manufacturer's instructions when using spray equipment. For airless spraying use a 0.013 to 0.015" tip at 1500 to 1750 psi. Do not paint in direct sun or on hot surfaces. Stop application two hours before rain or heavy dew. If possible, plan your painting to avoid rain and moisture for the first 24 hours of curing. Caulk seams and edges after painting.

NOTE: Do not use as a primer over silicone caulks.

Tinting

UMA Brand can be tinted with up to four ounces of universal colorant per gallon.

Dry & Recoat

Dry and recoat times are based on 70ºF (21°C) and 50% relative humidity. Allow more time at cooler temperatures. Thicker coats will take longer to dry. Dries to the touch in 30-45 minutes and can be topcoated in 3 hours (will vary with temperature). Allow 24 hours before applying two-component paints. It will be fully cured in 7-10 days. It can be nib-sanded in 3 hours and lightly sanded after 24 hours.

Clean-Up

Clean up tools and equipment immediately with soap and water. Clean-up spatters and spills immediately with warm water. If UMA Brand sets up or dries, remove with XIM GON or lacquer thinner. Properly discard empty container.
