Roof Cleaning in Oregon

The approved cleaner for roofs is a variation of pool grade chlorine that is mixed with surfactants to allow dwell time on steep surfaces. There are downsides to using this mixture when it is first mixed and hot. Some of the downsides are it can kill plants along with the moss and mold so you have to be more careful in prep work so that you do not kill plant life. Also, when it is hot or freshly mixed on hot days it has an off gassing of chlorine gas which is also harmful and can even be fatal if PPE is not used. Even with all these scary things, chlorine is used in drinking water and cleaning without to much issue if used appropriately.. It also degrades rather fast and become inert quickly with UV exposure.

Another option is available but a bit more costly and friendly to use...

"Sodium percarbonate mixed with titanium dioxide"
" breaks down volatile organic compounds into harmless, inert materials and carbon dioxide. It is safe for plants. It contains inert materials disappear into the soil. Bleach is chlorine — a toxic substance that can kill plants and animals and can be very harmful to your lungs. Prolonged use of bleach will damage paint, destroy roofing underlayment and asphalt shingles."

Having used both types of cleaners and weighing the benefits of both, I have found that the Percarbonate type cleaners work but not as quickly as the Chlorine mixes. Both will work but one requires more work and cost overall, and you you still have to take the same amount of caution to not overspray or get into the waterways. both products go inert, but may still need capture depending on the areas being cleaned.

Bad Concrete Finish Fixes

What to do with bad concrete coatings.

In the Pacific Northwest there is a ton of different concrete finishes being used in the industry. Many have performed well under the duress of constant weather and environmental changes.That said, there are more that have failed or have become unsightly than have lasted to a satisfactory level of enjoyment. Having the proper maintenance program for concrete cleaning and sealing becomes a high priority if the desired outcome is aesthetic durability and beauty.
A licensed contractor does not mean they are up to date on the best sealers, stains and coatings. Fast finish provides an in depth evaluation that goes beyond the standard one size fits all or in this case one coating or sealer works in every case. Having a broader product and applications background enables Fast Finish to provide a better solution than what most contractors offer. 
Another overlooked area regarding sealers and coatings is the short window in Oregon for application. Booking and planning in advance for the following season is usually the best approach and does not leave you with a run of the mill finish that is often provided in the area.

What about TSP as a cleaner?

We use TSP for some things but here is some things to know for those who are looking at adding Soft Wash services to their pressure washing services...
Soft Wash differs from pressure washing in that it primarily relies on chemistry to do the heavy lifting in the cleaning process.,.
Note: TSP is (SH) or bleach compatible-
((Soft wash))
As a rule, you should Avoid adding TSP to your soft-wash mixes for two primary reasons:
1.  If left to accidentally dry on glossy surfaces such as windows or shiny gutter or garage doors, TSP will cause permanent damage to the shiny surfaces and 'De-Gloss' paint or glass and stain metal and cement surfaces.
2.  Use of TSP will give the possibility of violating the Clean Water Act or CWA.   If evidence of pollution by TSP or other pollutant by your company's services cause a fish kill, waterway plant death, eutrophication of nearby bodies of fresh or salt water, you may be held liable.  It is rare but can cost thousands in fines as warnings are almost never heard of.   Many states only allow the sale of a TSP substitute. ( found at HOme Depot)
-TSP is basically good for preperation of re painting and treating mold on wood or painted surfaces...

Penetrating vs. Topical Sealers

Question-Can topical concrete sealers (ex. acrylics, epoxies, urethanes, etc.) be applied over penetrating sealers?

Answer-((Yes,))topical sealers generally can be applied over most penetrating sealers. Penetrating sealers generally do not form a membrane, film, or barrier that would prevent the topical sealers from adhering to the surface. As a matter of fact, most penetrating sealers were originally developed for use as primers to be applied prior to topical coatings and sealers being applied. It was only in recent years that penetrating sealers gained popularity for usage as a standalone product due to their inherent properties for preserving, protecting, and strengthening concrete, brick, and stone surfaces. Please consult product label and product specification sheet for specific details on the product you are considering.
Can penetrating concrete sealers be applied over topical sealers? 
No, topical sealers create a membrane, film, or barrier that prevents the penetrating sealers from absorbing into the surface. If intention is to apply a penetrating sealer to a surface, then it will be necessary to properly remove the topical sealer from the surface prior to application of the penetrating sealer. Removal may be accomplished through scraping, grinding, sand blasting, shot blasting, pressure washing, chemical stripping, or other accepted method
