A raíz del cambio, decidimos imprimar el tablero chapado.

Yes. A raíz de is a common fixed expression meaning as a result of, following, or because of something, often with the idea that one event led to another.

So A raíz del cambio means something like following the change or as a result of the change.

A few things to notice:

• It is an idiomatic expression, so learners usually need to memorize it as a chunk: a raíz de + noun
• It is slightly more formal or written-sounding than simply saying por in many cases
• It often introduces a cause or trigger

Examples:

• A raíz del accidente, cambió de trabajo.
• A raíz de la reunión, tomamos otra decisión.

Because de + el contracts to del in Spanish.

So:

• de + el cambio → del cambio

This contraction is required in normal Spanish.

Compare:

• a raíz del problema
• después del partido
• cerca del centro

One important exception:

• If el is part of a proper name, it usually does not contract
  Example: de El Escorial

But in del cambio, it is just the normal masculine singular article, so the contraction is necessary.

The comma is used because A raíz del cambio is an introductory phrase placed at the beginning of the sentence.

It sets the context before the main clause:

• A raíz del cambio,
• decidimos imprimar el tablero chapado.

In Spanish, this comma is very natural and helps readability, especially when the introductory phrase is not very short. You may sometimes see short introductory phrases without a comma, but here the comma is perfectly standard.

Decidimos can be either:

• present: we decide
• preterite: we decided

These two forms are spelled exactly the same for nosotros with decidir.

In this sentence, context strongly suggests the preterite: we decided. The sentence sounds like it is describing a completed decision made after a change.

This is common in Spanish. Some verb forms are identical in the present and preterite for nosotros:

• hablamos
• comemos
• vivimos
• decidimos

So you often have to rely on context.

Because decidir is commonly followed by an infinitive when you say what someone decided to do.

Pattern:

• decidir + infinitive

So:

• decidimos imprimar = we decided to prime

More examples:

• Decidí esperar.
• Decidieron salir temprano.
• Hemos decidido cambiarlo.

This works much like English decide to do something, except that Spanish does not need a separate word like to before the infinitive.

Imprimar means to apply primer or to prime a surface before painting or finishing it.

It is a technical or trade-related verb, especially common in contexts like:

• painting
• construction
• carpentry
• manufacturing

It is not as common in everyday conversation as more general verbs, but it is completely normal in the right context.

In Spain, imprimar is a standard term for applying a primer coat to help paint or another finish adhere properly.

Examples:

• Hay que imprimar la pared antes de pintarla.
• Imprimaron la madera antes del acabado final.

They look similar, but they do not mean the same thing.

• imprimar = to prime / apply primer
• imprimir = to print

This is an easy mistake for learners because the words are visually close.

Examples:

• Voy a imprimir el documento. = print
• Voy a imprimar la superficie. = apply primer

So in your sentence, imprimar is definitely the technical finishing verb, not anything to do with printing.

Grammatically, tablero chapado is a noun phrase:

• tablero = the main noun
• chapado = an adjective describing the noun

So chapado agrees with tablero in gender and number:

• tablero is masculine singular
• therefore chapado is masculine singular too

If the noun changed, the adjective would change too:

• tabla chapada
• tableros chapados
• tablas chapadas

In this kind of context, chapado usually means veneered or covered with a thin layer of another material, especially wood veneer.

Because in Spanish, most descriptive adjectives normally come after the noun.

So:

• tablero chapado not usually
• chapado tablero

This is the standard position for many adjectives that classify or describe material, type, or condition.

Here, chapado is not adding a poetic or emotional quality; it is simply identifying what kind of board it is, so the post-noun position is the natural one.

Sometimes yes, but the nuance is a little different.

• A raíz del cambio = as a result of the change / following the change
• Por el cambio = more directly because of the change

A raíz de often suggests that one event happened in response to or in the wake of another. It can sound slightly more formal and a bit more tied to a sequence of events.

So por el cambio might be understandable, but a raíz del cambio sounds more natural if you want to emphasize that the change triggered the decision.

Yes, it feels quite compatible with Spain Spanish, especially because of the technical verb imprimar, which is widely used in Spain in painting and woodworking contexts.

That does not mean it would be impossible elsewhere, but the overall wording has a fairly technical, European Spanish feel.

Also, the sentence sounds like something from:

• a workshop
• a manufacturing process
• carpentry instructions
• a project report

So a learner should recognize that this is not very casual everyday vocabulary, even though the grammar itself is standard.
