Composite Deck

Do I Need To Seal My Composite Deck?

Is composite decking something you need sealed? And how would you seal a composite deck if you did? 

Although we cannot respond for every composite brand available on the market, we can address your question especially with reference to Superdeck.

To Seal or Not to Seal?

Prior to commencing, it is imperative to establish the evidence. A lifespan of routine deck maintenance is required for owners of natural timber decks. They must repair, sand, and reseal their decks every 2 to 5 years to maintain their appearance and preserve it. The “cost” of the inexpensive deck they acquired a decade ago has significantly increased for them and will continue to do so, as the cost of maintaining a deck surface is not inexpensive. 

Certainly, you have the ability to do it independently. Is your backup plan sufficient? And you are still required to purchase the necessary products to maintain it.

Boards that are sealed on all four sides

In comparison to natural wood decking, composite decking is produced from a blend of plastics and wood fibres. Composite decking necessitates significantly less maintenance than its natural timber counterparts. 

This core is subsequently entirely safeguarded by a robust and enduring polymer barrier that envelops the entire board. By employing a co-extrusion process, this shield is heat-pressed onto the core, thereby establishing an impermeable protective barrier against moisture, ultraviolet (UV), insects, and pathogens. 

We undertake all of this in order to offer you a deck that is both durable and can be relished for an extended period of time without requiring any effort from you.

Indeed, composite decking needs only occasional cleaning, which is a common practice regardless of the material of the deck, whether it be timber, paving, or composite. Except in cases where your deck is not completely sealed on all four sides. Therefore, it is imperative to enquire about the composite deck’s sealing on all four sides when purchasing it.

While it is raining, do not water your Lawn

In the event that your composite deck is not sealed on all four sides, it is susceptible to insect infestation and weather exposure, which can result in decaying and deformation, similar to a natural timber deck. 

In addition to being susceptible to these undesirable elements, an unsealed composite or timber is also susceptible to mildew, discoloration, and staining, which can reduce the lifespan of your deck and alter its appearance.

If you have invested in a low-cost composite decking brand in order to reduce expenses, you may find that you are obligated to incur ongoing maintenance expenses that are equivalent to those of a natural timber deck. 

No manufacturer of composite decking that is entirely sealed and of high quality recommends the application of coatings or sealants to their product.
