Low Voc Polyurethane Deck Coating}

Low-VOC Polyurethane Deck Coating


Steve A. Parker

Low-VOC polyurethane-based formulations are some of the most important products to have come out of manufacturers’ labs to satisfy the requirements for deck coatings of commercial and industrial facilities. These new line of deck coatings are very flexible in any type of weather conditions and boast of more functional and decorative features that help repair, protect and enhance all types of decks.

Polyurethane deck coatings maintain deck quality as liquid-applied single-components coatings. These polyurethane deck coatings come in concrete, gray, or tan colors and are moisture-cured and slip-resistant, characteristics that are very suitable for waterproofing trafficked or pedestrian areas like parking decks and roof decks.

Low-VOC deck coatings are also suitable for exterior and interior applications and retain their elastomeric properties in extreme temperatures such as freezing weather or very hot climates.

Applying Low-VOC Polyurethane Deck Coating

Low-VOC polyurethane deck coatings can be applied in any types of decks. For lightly-trafficked surfaces such as patios, roof decks and sun decks, low-VOC deck coatings can be applied to a primed concrete surface using one liter of paint to around 1.57 square meter of deck area. This will result to .63 centimeters of thickened film. To avoid pinholes, extra care should be taken when applying the deck coatings, applying the formulation as uniformly as possible. If pinholes are unavoidable, immediate repair should be done on the surface.

A low-VOC glaze is then roller-applied, although brush or spray painting can also be used to achieve a 0.4 millimeter film thickness. A gallon of sand is immediately broadcasted uniformly into the wet surface, with backrolling done on the surface to evenly distribute the deck coatings. Generally, it takes only an overnight curing process before the deck surface can be used for pedestrian traffic once again.

In the case of medium- to heavily-trafficked deck areas, the initial coating application of low-VOC deck coatings is allowed to cure overnight. Another layer of deck coatings is applied the following day and sand is broadcasted to the surface. The coating and sanding process is repeated in as many days as recommended by manufacturers, until a final top coat is applied and allowed to cure for 3 days to complete the deck coatings system.

Low-VOC Polyurethane Deck Coating Materials

For a complete and correct application of the deck coatings system, there are several materials used in the process. The main material is the low-VOC polyurethane coating whose main use is to waterproof the deck membrane with its elastomeric properties, usually a one-part and self-leveling formulation that also interacts with the sand aggregate. Another material is the two-component and solvent-based epoxy primer that prepares concrete and metal deck surfaces prior to coating application.

A single-component and non-staining polyurethane sealant is another material used in deck coatings systems. When cured at the right temperature, it becomes rubber-like, which is flexible and tear-resistant. To increase slip- and wear-resistance, sand aggregates are used at every coating layer. To complete the deck coatings system, a polyurethane top coat is needed to protect the deck coatings from ultra-violet exposure.

You Can Get Paid To Take Surveys But Can You Really Make Money At It?

By Jorge Chavez

With all of the paid survey activity on the Internet, it is easy to get paid to take surveys. More than 700 survey makers offer paid online surveys in the U.S. alone. Almost all of these are looking for more survey participants. Internationally you can get paid to take surveys made by over 3,000 different survey makers.

The challenge is not just to get paid to take surveys – that’s easy. The challenge is to find the legitimate paid surveys that pay well, avoid the time-wasters that don’t, and make money at it.

80% of the money is made through 20% of the survey makers and their surveys. From the point of view of those who want to really get paid to take surveys and make money in doing so, only about 1 in every 5 survey makers is truly worth dealing with. Another 40% are marginal, and about 40% are time wasters, to be avoided.

The key to making money with online paid surveys is in the list of survey makers that you sign up with as a prospective survey taker. You might think that it would be easy to get such a list, but it’s not. The survey makers that pay poorly or not at all are constantly losing participants and must recruit new ones.

They pay recruiting fees to anyone who can bring them “fresh meat”, new participants that don’t yet know the ropes. These high recruiting fees mean that anytime you go to look for survey makers on the Net, you will be inundated by offers for “free lists” and ads recruiting survey participants.

Almost all of the offers and ads you will see will be recruiting for the survey makers that don’t pay or don’t pay well. They are trying to fill recent vacancies left by participants who were expecting to get paid to take online surveys, were not paid, were disappointed, and quit.

You generally won’t find good lists where the survey makers are paying the list purveyors to recruit you.

But you can find a good list, one that will help you really get paid to take surveys, with one of those paid survey membership sites that maintain lists for their members. For a smallish membership fee they will share their list with you. You pay, so the guide will take you where YOU want to go.

When choosing your paid survey membership site, look for two things: 1. A very strong money-back guarantee, backed up by a financial company or bank. 2. A low refund rate under that guarantee. The guarantee means that the site stands behind its service; you like their service or it costs you nothing.

The low refund rate means that the current members like the service there and feel that they got full value for their small investment. You will want to join a group like that.

A high refund rate means many unhappy clients demanding their money back. This is a group you will want to avoid becoming part of.

There are sources of information on paid online surveys that can help you to really get paid to take surveys. You can start with a good, objective, paid survey review site like that cited below, for more explanation and information.
