What about flashings around chimneys?

Roof Restoration Systems by Preservation Products do not require separate flashings. The liquid-applied elastomeric coating is self-flashing, creating an effective weathertight seal. 

How long do elastomeric coating systems take to dry?

The dry time for Acrymax roof and wall coatings depends greatly on a number of factors, including temperature, humidity, direct sunlight, coating thickness, and air movement. Darker colors will dry faster than lighter colors. Allow a minimum of 2 hours between coats.

During cooler weather applications, applicators must take note of not only the ambient temperature but also the dew point. If dew forms on the roof surface the coating will not dry.

What temperatures are best for application?

On cool weather application days, Acrymax coatings should not be applied when temperatures are below 45°F. Temperatures for 24 hours after application should ideally not fall below 45°F and must stay above freezing. At freezing temperatures, any water left remaining in the coating film can freeze and damage the paint film.

When is the use of polyester reinforcement required?

Polyester reinforcement adds dimensional strength to the membrane created with Acrymax elastomeric coatings. Polyester reinforcement is especially useful at transitions, flashings, for lining built-in gutters, for repairing and sealing leaking seams, and in certain cases over the entire roof area, particularly on smooth asphalt roofs. Our Roof Restoration Systems include two different levels of roof reinforcement.

Why two or more coats?

To perform effectively, a high performance coating system should be applied in a manner that will provide a continuous film of relatively equal thickness. The most effective way to do this is with multiple coats. In fact, 3 or 4 coats are often used for maximum protection. When polyester reinforcement is used, a minimum of 3 coats will be required.

How difficult are Acrymax coatings to apply?

Acrymax are waterborne coatings that can easily be applied by brush, roller, or spray. They clean up easily with water.

What does inspection after application involve?

Inspection means going over the finished application to ensure that the application has been completed properly. If necessary, additional material is applied during the inspection to ensure complete and uniform coverage. After final completion, it is an industry recommendation that all roof systems be inspected twice a year.

What does application involve?

Application requires applying Acrymax coatings conscientiously under proper conditions, applying all materials that are specified in the manner specified, and using good construction and roofing practices.

What is involved in the Specification phase of application?

After assessment of the present condition and the individual requirements of the roof, a Preservation Products guideline specification can be developed, which will include: surface preparation, material selection, quantity of materials, number of coats, and if and where polyester reinforcement will be used. Three general specifications have been developed for metal roofs: the Preservation System, the Restoration System, and the Reinforced Restoration System.
