" Many outside areas of you home get dirty over time. Pressure cleaning is an effective way for quickly cleaning the outside surfaces including gutters, decks, vinyl siding, precast concentrate stuff, and stubborn machinery surfaces. Pressure cleaning makes fast work of outdoor cleaning project. Here is how you can get a lot of cleaning done in just one day. First, you'll need to rent a pressure cleaner. Pressure cleaners can be rented by the day from local rental companies or hardware store. Pressure cleaner are usually gasoline powered pressure pump, which spray a mixture of either cleaning agents and water or just high pressure water at the surface you're cleaning. They make short work of difficult cleaning situation. Let's get started and see what we can get done in just one day. Let's start with the back porch. We're going to clean the gutters and soffits and then the pressure treated wooden deck. Before you start, prepare the surrounding area for cleaning. Start by tightly closing all the doors and windows. Remove the deck furniture, plants, and any other odds and ends that may be on the porch. The deck should be completely cleared of everything. Set the furniture a good distance away because the spray and fine mist from the pressure cleaner travels quite a ways. Carefully follow the specific instructions provided by your rental company. Check to make sure that the pressure cleaner has a full tank of gas. Nothing is more frustrating than running out of gas in the middle of the project. Following the specific instructions for your pressure cleaner, attach one end to the pressure hose to the fitting on the pressure cleaner, and the other end of the pressure hose to the pressure cleaning wand. There are many specialized cleaning agents for use with pressure cleaner. For general cleaning, we selected a nontoxic biodegradable general purpose cleaning solution, which will do an effective cleaning job and not damage the nearby plants. Following the instructions on the label, mix the cleaning agent with water in a bucket. Place the cleaner suction hose into the bucket of cleaning solution. The cleaning agent will be injected into the water supply when the soap tip is in used. There are four tips that can be inserted on the end of the pressure cleaner wand. Each tip has a different application. The soap tip, which is black in this case, is the tip that you use to apply the cleaning agent to the surface. Attach the soap tip to the end of the one. Attach your garden hose to the water inlet fitting on the pressure cleaner and turn on the faucet to feed water to the pressure cleaner. Always wear safety glasses when"

" It will protect and your clothes from the back spray of water, dirt, and cleaning agent. With the black soaping tip in placed, apply the cleaning agent to the highest area first, in this case, the gutter and the soffit. Allow the cleaning agent to loosen the grime for ten to fifteen minutes. While you're waiting, switch to the green tip. The green tip disperses water under pressure over 25 degree area. As you'll see, you use different tips to help set the pressure for different cleaning situation. The green 25-degree tip is good for mid-pressure cleaning situation. When the cleaning agent has a time to work, pressure clean the gutters and the soffits. Hold the wand at an angle to the soffits to avoid spraying water up and into the soffit vents. Don't work any closer than is necessary to remove the grime as too much pressure can damage the area that you're trying to clean. Moving on to the deck, replace the green tip with the black soaping tip. Apply a steady even coat of cleaning agent to the entire deck. Allow the cleaning agent to work for ten or fifteen minutes. Don't let the cleaning agent dry out during this time. Now, switch to the 40-degree white tip. This tip has wider 40-degree dispersion and as a result, it produces a milder pressure. Starting in the corner and moving away from the house evenly pressure cleaning the deck. Hold the wand about 15 inches away from the deck at an angle working in a sweeping motion. Don't hold the one too close to the deck or it could lift the paint right off damaging the wood grain in the process. If there is a particularly stubborn stain, grime, or mildew, hit the area again with soap and then, scrub the area with the stiff brush. When the gutters, soffit, and deck are completely pressure cleaned, rinse the area with freshwater from a garden hose. This step is important because some of the cleaners leave an uneven stain or film if they're not rinse away before the area dry. Make sure that all the surrounding walls and windows are thoroughly rinse as well. Cleaning vinyl sidings is another common use for pressure cleaning. Prepare the surrounding area. Close and latch all the windows and doors. Cover all nearby such as utility meters, air-conditioning unit, and exterior outlet. As an added precaution, turn off the circuit breaker to any electrical equipment that might get wet. For vinyl sidings, we again used the general purpose biodegradable cleaner. Attach the black soap tip to the wand to apply the cleaning solution to the vinyl siding. When cleaning siding, it's important to shoot both down and at an angle from the opposite side of any siding joints; otherwise, you'll shoot pressurized water up under or into the joints. Working from a ladder, apply the cleaning solution with broad sweeping motions beginning at the top of the sidings and moving downward in a side-to-side motion. Keep the stream of water away from the windows to prevent the water from being driven into the seams. Always point the nozzle downward to avoid driving the water up and under the siding. After the cleaning solution has been applied, wait ten to fifteen minutes for the solution to work. Switch to the green 25-degree tip. This tip will apply a moderate cleaning action. Begin to clean the siding working from the topdown. Hold the spray nozzle at a downward angle between one to three feet from the siding."

" Switch back to the black soaping tip to apply the solution. Thoroughly saturate the masonry with the cleaning solution. When cleaning stone work, use the same process covering the surface completely with cleaner. Allow the cleaner to dissolve the mildew and grime for ten to fifteen minutes or more, but do not let the surface dry. For poured concrete, use the yellow 15-degree tip, which will apply the most concentrated pressure."

" pressure of the green tip is easier on the cement joints between flagstone or slate reducing the chance of damage. Slowly work your way along the surface with even overlapping passage. Brick work gets the same treatment. Again, using the moderate 25-degree green tip. With pressure cleaning in just 1 day's time, you can completely transform the exteriors of your home, restoring wooden decks, vinyl siding, precast concrete, stone, and masonry to their natural color and beauty."

Spraying on and Painting a Heat-reflective Pool Deck Surface
Spraying on and Painting a Heat-reflective Pool Deck Surface

Don Humphrey is spraying a cement and polymer mix from Innovative Concrete Technology called Texture-Krete 2000 onto the pool edge and deck in Punta Gorda, Florida. He moves in a circular motion to splat the cement mix onto the deck. As the gloss begins to leave the spots, a crewmember follows behind to knock it down with a trowel. This removes the pointy tops but leaves a 1/16-inch stucco pattern to the pool deck to make it easy to walk on. The deck is cleaned and scratched to remove any rough points before Humphrey and his crew apply an acrylic paint to the textured deck surface. The key to a well-sealed surface is to roll the paint firmly into all the nooks and dips in the surface. Bob talks about the embedded deck drain set in the concrete that is pitched slightly away from the pool. Excess water and dirty deck water drains away from the pool and is carried off to the sides of the pool deck by the deck drain. Humphrey applies two coats of paint and a topcoat for protection. The deck can be maintained with gentle soap-and-water washing to prevent any white spots from drying chlorine on the painted surface. Humphrey says the paint should last three to five years before it is redone. One key to maintaining the surface is to avoid abrasive cleaners or power washing. Should any mold or mildew attack the surface, Humphrey suggests using a mild bleach-and-water solution to kill the mold. The oyster color the homeowners have selected should wear well and stay cool in the hot Florida sun. Editor�s Note: The deck surface product with cooling properties used in this application was not Kool Deck from Mortex.

Preparing to Paint the Victorian's Exterior
Preparing to Paint the Victorian's Exterior

Bob joins Ron Boyajian and the painters for the prep work and painting of this 100 year-old wooden Victorian. The painter explains that they power wash the surface with a 50/50 mix of bleach and water to blast away loose paint and kill any mildew. He then shows how to feather the edges of the paint with a sander for a smooth finish. A drop cloth, and a catch on the sander keep chips out of the soil, but it's critical to check for lead content in the paint before disturbing it. Boyajian shows Bob the moisture meter used to check the moisture content in the wood and verify the right type of paint to use on the surface. At around 10 percent moisture, a latex paint will adhere without peeling, but at 25 percent, oil-based paint will peel, so it's important to get an average for the house. Boyajian gives Bob the basics on priming before painting. At 60 percent bare wood, he says it's best to prime the entire house. California Paints uses their Trouble-Shooter linseed-oil-based primer to hold back the tannic acid in the new cedar clapboards so that they won't bleed into the new paint. The painter shows the proper technique for covering clapboards, using a hand-brushing technique to cover the butts first and then the face of the clapboards for good coverage. This primer is tinted to half the depth of the color of the finish coat so that it will hide any imperfections in the top coat.
