AMES'® Maximum-Stretch
Do-It-Yourself in Three Easy Steps:


Sku numbers

1. Clean and Prepare the Roof or Wall

Read all label instructions before beginning. Always run a test patch first in an inconspicuous area, to ensure that proper adhesion and drying occurs and the product works to your satisfaction. Be sure surfaces are clean and dry before applying Maximum-Stretch. All major cracks, joints and seams should be caulked with Blue Max trowel-grade liquid rubber. Do not use a silicone caulk. Follow seam taping instructions. Mask all sensitive areas before starting.


2. Seam Tape Where Needed

It is important to seam tape all joints and cracks to avoid future cracking and leaking. Seam tape flashing to wood; wood to wood; concrete to wood; metal to wood; brick to wood; etc. Apply around flashings, windows and cracks in the walls. Refer to Ames Seam Tape label (PS250, PS450, PS650) for application instructions. Do not use fiberglass or asphalt impregnated seam tape.

3. Pour It Out & Paint It On

Apply 1-3 coats as needed, depending on the level of waterproofing you wish. Typical applications are 1-2 coats on above grade walls, 2-4 coats for below grade walls (30 mils thickness), and 1-3 coats for roof maintenance. On roofs you may simple pour it out and paint it on. Apply with a paint roller, a broom, or for larger jobs use a commercial airless sprayer.

Good: 1 -2 coats or up to 2 gal total per 100 square feet.

Better: 2-3 coats or up to 3 gal total per 100 square feet.

Very Best: 3-5 coats or up to 3-5 gal total per 100 sq. ft.

(Recommended for extra protection over difficult surfaces). Cured coating should be about the thickness of a quarter. For flat tar roofs with ponding water or rusty metal situations, see Ames' Super Elasto-Barrier or Vapor barrier product specifications and suggestions.

Weather & Drying Guidelines
Maximum-Stretch is best applied between 40 to 90 degrees F. on warm dry surfaces. Apply when the streets are dry, the sun is in the sky and no inclement weather is forecast. Dries in 1-2 hours, depending on thickness of application and weather; cures in 24 hours. Low temperatures, high humidity and evening and morning dew will require increased drying/curing time. Maximum-Stretch is designed to be UV cured. When it has not been UV cured it may have a slight tack until it has had some sun contact.

Application Tools for Maximum-Stretch
Ames' industrial-strength coatings are easy to apply for the Do-It-Yourselfer. Most Ames products may be applied by brush, roller, push broom, or sprayer. Ask for a sprayable-grade coating when applying by sprayer. Depending upon the roughness of the surface, preparation, and the specific application, you may need one or more of the following:




Estimated Coverage

Standard product coverage on a smooth surface is 100 sq. ft. per gallon (est. 10ml). More than one coat recommended. More coats equal longer life.
