Directions

Tools Typically Required: Utility knife, painter’s tape, or foil for protecting surfaces. Safety Precautions: Always wear eye protection, gloves, and proper work clothes when using Gaps & Cracks. Protect surrounding work area from accidental foam overspray. Cured foam is difficult to remove from skin, clothing, and other substrates. May discolor skin. When transporting cans by passenger car leave the container wrapped in a cloth in the trunk, never in the passenger compartment. Surface Preparation: Ensure all surfaces are stable, clean, and free from dirt, dust, oil, and other contaminants likely to impair adhesion. Surfaces can be moist but not frosted or iced. Cover surfaces not intended to be foamed. To ensure full and even curing of the foam on porous substrates (i.e., brickwork, concrete), moisturize surfaces with water spray before application. General Preparation: The temperature of the working area and the product should be between 41°F (5°C) and 86°F (30°C). When working in cold conditions, can should be stored above 41°F (5°C) at least 12 hours before application. Shake can vigorously before use for 30 seconds (15-20 times minimum). Screw the foaming straw applicator completely onto the can valve using caution to avoid activating the valve. The outflow rate of the foam can be adjusted by pressing and releasing the trigger. Note: to become familiar with the product, test on an experimental surface by inverting can and slowly depressing the trigger to dispense foam. Continue use in an inverted orientation. Application: Holding can upside down, press the trigger which controls outflow rate of the foam. Dispense the foam sparingly, filling the joint initially by half to avoid excessive overflows, as foam will expand. Shake can regularly during use. Slight misting with water can speed cure. Release trigger 5 seconds before the end point but keep straw end moving. For deep section application, allow the first layer of foam to cure before applying a second layer. Foam can be trimmed with a knife after an hour. Foam will be fully cured in approximately 24 hours. It is recommended foam be protected from UV radiation by a protective covering or coating such as paint, plaster, mortar, etc. to avoid discoloration. Note: Ambient temperature and humidity can affect foam curing and maximal joint width. In dry conditions, to get the best foam structure and properties, it is recommended to fill gaps and joints in several layers by the application of smaller foam strings (up to 1-inch thickness). At very dry conditions, the foam may be brittle after hardening. This brittleness is a temporary effect and disappears after a while or by warming up. Clean-up: Clean tools and uncured foam residue immediately with acetone. Cured foam must be carefully cut away with a sharp-edged tool. Product must be stored vertically, not horizontally on its side. Store in a cool, dry place for maximum performance and shelf life. Do not store below -4°F (-20°C). Below this temperature the product valve may spontaneously open, resulting in leakage. Product may be stored for a maximum of 1 week at -4°F (-20°C). For extended storage periods (longer than 1 week), store between 41°F and 77°F (5°C and 25°C). Containers are under pressure. Do not expose to open flame or temperatures above 120°F (49°C). Do not store under direct sunlight. Excessive heat can cause bursting and premature aging of components resulting in shorter shelf life. When containers are empty, vent off any excess pressure. DO NOT discard empty can in garbage compactor. DO NOT incinerate. DO NOT puncture, cut, or weld container. Recommended method of disposal for unused product: Vent off excess pressure and dispose of in an appropriate waste receptacle. Dispose of according to federal, state, and local governmental regulations. DANGER! EXTREMELY FLAMMABLE. VAPOR MAY CAUSE FLASH FIRE. VAPOR AND SPRAY MIST MAY CAUSE LUNG DAMAGE. MAY CAUSE ALLERGIC RESPIRATORY AND SKIN REACTION. CONTENTS UNDER PRESSURE. DANGER! Contains methylenediphenyldiisocyanate, dimethylether, chlorinated paraffin and hydrocarbon propellant mixture. Do not use near sparks, heat, or open flame. Vapors will accumulate readily and may ignite explosively. Ventilate area during use and until all vapors are gone. DO NOT SMOKE WHILE USING. Extinguish all ignition sources. If burned, dried foam may release hazardous decomposition products. Dried foam may be combustible if exposed to flame or temperatures above 240°F. Avoid prolonged exposure to sunlight or heat from radiators, stoves, hot water, and other sources of heat that may cause bursting. KEEP OUT OF REACH OF CHILDREN.
