Timber Block Home Owner Application and Maintenance

Please read this Application and Maintenance Guide carefully before you start applying the field coat of WoodPlus’ Timber Block Classic Translucent Collection or Authentic Opaque Collection coating. Keep in mind that preparation is the key to achieving quality results. The Timber Block Classic Translucent and Authentic Opaque Collection coatings are manufactured in Canada by WoodPlus™ Coatings for exclusive use by Timber Block on its engineered homes.

Preparation and application instructions

Your respective WoodPlus Coating warranty only takes effect after the field coat (third coat) of Timber Block Classic Translucent or Authentic Opaque Collection coating has been applied by the original purchaser (property owner) or first transferee1 (application instructions are detailed below) within the first six (6) months following the construction of the engineered home. In order to maintain the validity of this warranty, the homeowner must also meet the following conditions:

Application Procedure:

Inspect all exterior wood surfaces to ensure that they are clean and free of any damage. Any noticeable damage on the wood should be repaired immediately before starting the application.

Clean thoroughly any traces of dirt and/or mildew using a garden hose with a soft bristle brush (similar the type of soft brush you would use on your car) and a non-chemical cleaner such as TSP. Rinse all surfaces carefully and let them dry before applying the coating. WARNING: DO NOT USE A PRESSURE WASHER TO CLEAN SURFACES AS IT WILL DAMAGE COATED SURFACES.

NOTE: The original purchaser (property owner) or first transferee1 color selection for the home, if different from the standard colors already agreed to by Timber Block and WoodPlus, must be pre-approved by WoodPlus to ensure that the type of color chosen by the homeowner will offer sufficient resistance to color fading effects due to UV exposure.

Apply one (1) coat of Timber Block Classic Translucent or Authentic Opaque Collection stain over the two original coats applied by Timber Block at the factory. Coverage per gallon should be a minimum or 300 square feet and a maximum of 400 square feet.

Observe all coating maintenance instructions described below.

NOTE: For included trim materials, if your chosen color differs from the base coat, you will need to apply two (2) base coats and then one (1) coat of your chosen color in order to match the finish on the wall panels. You must coat all six (6) sides of the trim included trim materials.


WoodPlus has approved specific brushes for use with Timber Block products. In order to achieve the finishes represented in the Model Homes and marketing collateral, you should employ one of these options.

WoodPlus Coatings Group recommend the use of nylon/polyester (synthetic) brushes (size 3 ½” or 4”) for decks and siding. Nylon/polyester brushes are durable, maintain their stiffness in humid painting conditions, and clean the easiest. You can’t go wrong with a professional nylon/polyester brush like the ones featured below:


Clean all surfaces on a regular basis using a garden hose and soft bristle brush to eliminate traces of dirt, mildew or pollution. The eastern and northern surfaces of your home are more susceptible to the accumulation of mold and mildew. Pay special attention to these areas when cleaning surfaces.

Inspect surfaces on a regular basis and immediately repair and touch up any visible damaged area to prevent further deterioration of the coating.

We recommend regular inspections and the application of a maintenance coat as needed.

Smooth wood surfaces:

Wood must be clean and dry.

Remove all dirt dust, wax and grease.

Remove all sanding dust with clean rags and acetone prior to application.

Ensure that the environment is free of dust throughout the application and drying stages of the project.

Rough or textured surface:

Wood must be clean and dry.

Remove all dirt, wax, and grease with a soft brush attachment on a garden hose then allow wood to dry before coating.

1The “First Transferee” is the first owner occupant of the home if it was originally purchased and constructed by a developer or constructor.


General – product application:

Once the wood surfaces have been properly prepared, please observe the following DO’S and DON’TS of application:

DO NOT thin. The product is ready to use from the can.

DO NOT apply in direct sunlight or when the surface is warm to the touch.

DO NOT add any adhesion promoters, extenders or additives to the product.

DO NOT apply in wet weather or when inclement weather is imminent.

DO NOT allow the product to freeze. Keep any excess coating indoors until it is used.

DO NOT use chemical strippers/cleaners to clean surfaces before coating.

DO perform a color check to make sure it reflects what you had in mind for your project.

DO use a high quality nylon polyester brush (preferably Purdy or Corona) – minimum 3 inches wide (75mm) and bristle length equal to or greater than the width of the brush.

DO ensure that the product is kept free of all debris and is agitated (stirred) frequently throughout the application.

DO apply liberal coats of the coating on all surfaces of your project.

DO completely saturate all wood end grains as well as nail and screw holes.

DO maintain a wet edge and apply in the direction of the grain.

Best Practices for a Successful Topcoat Stain Application

IMPORTANT:  This document provides best practices for applying the field finish coating to a Timber Block home.  In addition to the manufacturer’s application instructions, we have collected recommendations from experienced professional painters who have applied the field coat to dozens of Timber Block homes in recent years.


The application of the field finish coat that will give the desired color to your home requires a delicate application and dress.  We advise you to use professional labor and read this guide and share it with your chosen painter.

Understanding and avoiding the consequences of overlapping layers when applying coating

The field finish coating is composed of pigments that create the desired color.  Each applied layer adds pigmentation and varies the final color.  For example, two coats of a brown finish applied to the base factory finish will create a darker brown than a single coat.  In addition, the natural characteristic features of the wood will be less visible.  For aesthetic reasons, and in order to get as close as possible to the standard samples colors, we recommend applying only one topcoat in the field.

Overlap is created when a coating layer is applied to a surface that has previously had some material applied.  Beyond the additional pigmentation, any drying of the previously applied material exacerbates the condition. Drying times vary considerably depending on temperature and direct sunlight.  In any case, as a water based stain, drying times are typically fast.  For example, if you start to apply the topcoat on the right side of a panel section and work top to bottom (like one would on a ladder) and then start the left side of the panel section in the same manner, even if applied immediately thereafter, one will almost certainly have an overlap in the middle of the wall section where the surface will have the equivalent of two layers of product because the right side will most likely have had time to dry before the left part is applied, thus creating a darker two coat coloration at that junction.

How then to avoid this overlap that creates a less than uniform appearance? Heat, direct sunlight, and ladder applications other than vertical trim coatings are the primary causes.  Although you must apply the topcoat when the temperature is 7O C (45O F) and rising, the heat is all the more worrying. 

Best practices:

  • In warm to hot weather, start very early in the morning. As soon as the sun reflects on the work surface, solar radiation will heat the surface and the coating you apply can often dry in 5 minutes and will automatically lead to an overlap negatively affecting the aesthetic appearance.  It is essential to coordinate the work so only surfaces in shade are worked during hot weather.
  • Avoid having fixed or unrealistic goals in terms of schedule and execution time because it is a job that requires one to be meticulous and disciplined. For example, a painter who decides to apply a color coating in a specific number of hours or days, such as “we’ll coat the house this weekend and it must be finished by Sunday night” regardless of weather conditions is all but doomed to failure;
  • Only apply the product when the temperature is 7O C (45O F) and rising and below 25O C (77O F)
  • You must apply the product on one or two full boards at the time. Use masking tape to limit the section you are working on in order to avoid overlap on installed mouldings or other sections already coated. 
  • Use a scaffolding, pump jacks, or a hydraulic lift platform for work at heights and not ladders, except for vertical trims, because the finish dries quickly enough that an overlap will be created while the painter moves from one stage of scaffold to another. When repositioning is necessary, use masking tape at the break point.
  • Keep a very wet brush and apply the coating liberally. Ideally, the amount of material used on the field coat will be as much as possible while not allowing the material to run or drip (see Fig. 1).  Using too little material results in an unacceptable finish (see Fig. 2). Finally, take care when approaching panel joints and other vertical seams in order to prevent runs and drips.

Other advice during the application:

  • If possible, according to the schedule of construction, coat the external window and door trims prior to installing them, it will ease the coating work;
  • The lighter the chosen finish coat color is, the easier the application will be.

If the work is unsatisfactory, you can add an additional coat, but be aware that the natural character of the wood will be less noticeable and the finish will be darker with more sheen.  A second topcoat will not have a negative effect on the longevity of the product.



The interior portion of the Timber Block insulated walls are factory clear coated.  Tongue and groove and all other bulk trims are untreated. Clear coating the interior will make the surfaces easy to clean and require little to no maintenance.  We recommend attaining a total of two coats of clear coating on all interior exposed wood surfaces (ie. one additional coat on wall siding, and two in the other bulk items).

  • For the clients wishing to stain the interior of their homes and obtain the best results, use WoodPlus’ Timber Block Classic Acrylic Coating on the factory coated and bulk uncoated materials.
  • Keep in mind that applying a colored stain to wood with tongue and groove joinery should ideally be done prior to its installation in order to ensure a coating of the tongue portion of the joint. If the color is applied after installation the natural process of shrinkage and expansion will expose the uncoated tongue.
