The Roof X Tender team is committed to helping you save time, prevent issues, and grow your business. The following best practices can be applied to all coating systems regardless of substrate or manufacturer:
Do: Ask occupants / tenants about roof issues and leak history.
Do: Check roof deck for deterioration along with possible wet insulation.
Do: Clean the roof surface the best way possible, preferably by power washing with a mild detergent.
Do: Check weather conditions when scheduling work and again before application.
Do: Prime surfaces before coating or repair applications, especially around drains and in low lying areas that accumulate dirt, grease and other foreign matter.
Do: Finish emulsion, acrylic and aluminum coating installation a minimum of 4 hours prior to sunset.
Do: Three course all repairs
Do: Apply coatings with airless sprayer, squeegee or double yoke industrial grade roller frame. Check individual product instructions.
Do: Follow manufacturer application requirements and coverage rates.
Don't: *Apply emulsion / acrylic products if temperatures are expected to drop below 50° within 24 hours of application completion.
Don't: *Apply emulsion, acrylic or aluminum products within24-48 hours of precipitation (dependent upon drying conditions).
Don't: *Apply emulsion, acrylic or aluminum products when experiencing dew, condensation, high humidity or other conditions resulting in the presence of moisture on coating surface during curing.
Don't: Install spray applied coating in windy conditions.
Don't: Apply coating without making all appropriate and required repairs first.
Don't: Apply acrylic coating in ponding areas without polyester reinforcement.
Don't: Forget to clean equipment with appropriate cleaner and seal all lids at completion of work day. *Note: Exceptions when using Quick Set technology.
For BUR – Built-up Coatings / Restoration:
Do: Inspect and determine if base flashings can be reinforced and restored or if replacement is required.
Do: Install a bleed blocking primer on all silicone projects.
Don't: Coat over problems and ignore issues regarding deflection in roof decks.
Don't: Coat over systems experiencing blisters or where existing coating is not fully adhered to base substrate.
For Metal Coatings / Restoration:
Do: Add downspout and/or gutters if undersized.
Do: Treat all rusted locations with wire brushing and then paint on a rust inhibitor or rust converting primer.
Do: Replace loose fasteners with next size larger.
Do: Seal all fastener heads with approved Roof X Tender sealant.
Don't: Apply coatings without sufficiently cleaning, or to rusted surfaces without wire brushing and applying a rust inhibitor or rust converting primer.
Don't: Apply coating products to pin holed areas. Deteriorated areas must be replaced.
Don't: Forget to treat all vertical laps with polyester and appropriate Roof X Tender sealant or Fleece Back tape.
Don't: Apply RX900 on top of butyl tapes.
For Single-ply Coatings / Restoration:
Do: Use RX 985 or RX 700 as first options before using RX 900
Do: Thoroughly clean and complete pull test according to manufacturer recommendations to verify need for primer and or adhesion of coatings
Do: Make all repairs and reinforce all laps with RX900 and polyester or Roof X Tender Repair tapes. Primer may be required
Do: Remember that RX900 dries very quickly. If reinforcing fabric is used, embed polyester immediately.
Do: When using RX900 to coat roof, apply first coat extremely thin at ½ gallon per square to avoid buckling.
Do: Ensure an engineer, consultant or owner approves decks / fasteners on single-ply systems that are mechanically attached
Don't: Use any other RX product to do repairs or coating other than RX900 without priming and verifying compatibility.
Don't: Expect a cheap painter’s roller without double arm supports to perform, it won’t. The roller sleeve will slide off and bend.
Don't: Spill or pour RX900 on single ply surface or it almost certainly will cause buckling of membrane. Usually the buckling relaxes over several days and will return to a nearly flat surface.
