TWP Stain Tip: Why Remove Old Deck Coatings When Switching to TWP Stains
TWP Stains have been around for over 20 years. They are one of the only EPA registered wood preservatives on the market today. Using the highest quality raw materials, TWP offers superb protection from UV discoloration, fading, rot, decay, and water damage. It can be used on nearly any exterior wood surface to enhance the wood’s natural beauty and provide years of protection.
When switching to TWP Stains for your outdoor wood project it is important to understand the fundamentals of stain application. In order for a stain like TWP to work effectively and give the most protection the wood surface should be cleaned prior to staining. All dirt, grime, mold, mildew, and graying should be removed completely. In addition, any old coatings should also be removed when switching to TWP stains.
Why remove old coatings when switching to TWP stains? This is so TWP can dive deep into the wood pores for maximum protection. If any old coatings of stain are left on the wood surface it can prevent a penetrating stain like TWP from doing its job. The new stain would simply sit on top of the old coating and would not be able to perform to its full potential. Removing any old coatings will reveal bare wood allowing TWP to penetrate and protect, as it should.
To remove old coatings when switching to TWP Stains, use a product like Restore-A-Deck Stain Stripper. Unlike a wood cleaner, a stain stripper will also clean the wood in addition to breaking down any old coatings so they can be removed during the cleaning process as well. It’s crucial to remove all the old coatings so TWP can perform as expected. Once this process is complete, maintenance with TWP is a breeze. The wood can simply be cleaned every few years and recoated with fresh TWP. This will result in a beautiful long lasting wood surface for many years of enjoyment.
